T&D distribute Ellis Patents cable cleats providing safety critical support to vital cable circuits. Cable cleats must withstand peak short circuit forces generated by the actual cable installation - Ellis Patents 3rd party certified cable cleats provide peace of mind containment of low and high voltage cables.
Ellis Patents are global leaders in the innovation and manufacture of nylon, aluminium and stainless steel cable cleats - EP satisfy the operational requirements of the construction, oil, gas, rail, utilities, wind energy and power generation industries.
Holding Power is Ellis Patents guarantee that EP Cable Cleats will contain dangerous short circuit forces - protecting your people, power and plant. Without fail - specify Ellis Patents Cable Cleats.
Alpha cable cleats contain single core power cables in trefoil formation - lightweight, fast to install, strong and robust with unique design providing labour savings. Short circuit withstand test : 31.4kA RMS (72.4kA peak).
Vulcan cable cleats for single, trefoil, quadrafoil and bundled cable installations - suits LV, 11kV-33kV BS6622 and BS7870 Triplex high voltage cables.
Made from stainless steel for non corrosive, high strength and permanent utility cable cleating with compact design.
Ellis Patents are a leading voice in the campaign to have cable cleats reclassified as short-circuit protection devices. A move that would mean cable cleats would be placed on a parallel with fuses and circuit breakers. "This reclassification makes absolute sense. In the event of a cable fault, the forces between cables reach their peak in the first quarter cycle, which is the point that cable cleats earn their crust. In contrast, circuit breakers typically interrupt the fault after 3 or even 5 cycles by which time, if the cable cleats are underspecified, the cables will no longer be secure, but will be putting vital electrical installations and lives at unnecessary risk," says Paul Nolan UK Sales Manager, EP.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

3M Cold Shrink QT-III 7600-3W and 7600 Series Cable Terminations - Specification
1. 1 of 13 3M
3M™ Cold Shrink QT-III Silicone
Rubber Three-Conductor Cable
Termination Kit, 7600-3W Series
5, 8, 15, 25/28 and 35kV
Product Description 3M™ Cold Shrink QT-III Silicone Rubber Three-Conductor Cable Termination Kit, 7600-
3W Series, are designed to accommodate medium voltage 3/C shielded power cables
without ground wires, and are available for indoor or outdoor application.
Each termination kit is supplied with the materials required for terminating one three
conductor cable. (Terminal or lug is not included in the kit and must be ordered
separately. Consult the 3M Electrical Products Catalog.)
All main termination components are produced from color-matched dark gray silicone
rubber. These components are:
Breakout Boot – an open-ended molded rubber sealing assembly that is factory
expanded and mounted on removable inner supporting plastic cores. Breakout boots
are supplied for field installation in a pre-stretched condition. The supporting cores are
removed after the boot has been positioned for installation around the breakout area of
a 3/C cable. Core removal allows the silicone rubber boot to shrink down to a pre-
determined diameter, creating an environmental enclosure for individual cable phase
legs and the overall cable jacket.
Re-jacketing Sleeve Assembly – a tubular silicone rubber insulating sleeve that
incorporates an inner-expandable polyester braid designed to reduce sliding friction,
and deliver the silicone tubing onto the cable phase metallic shielding. Re-jacketing
sleeves are designed to protect the shielded cable phase legs from exposure to
moisture, corrosion, ozone, ultraviolet radiation, physical contact and other hazards
associated with termination operating environments.
QT-III Termination – a one-piece cold shrink assembly that consists of skirted or
tubular insulator, high dielectric constant (Hi-K) stress control mastic and a built-in
environmental top sealing compound. The complete assembly is pre-stretched and
loaded onto a removable plastic core. Core removal allows the termination assembly to
shrink down and seal onto prepared cable phase insulation and lug barrel surfaces.

These terminations can be field tested using normal cable testing procedures
(reference: ANSI/IEEE Standard 400 “Guide for Field Testing and Evaluation of the
Insulation of Shielded Power Cable Systems”. Refer to most recent version).
The amount of airborne contamination determines the operating environment.
Operating environments are described as areas having varying degrees of airborne
contaminant or pollution severity that may, or may not, affect the long term performance
of terminations. These operating environments are defined as light, medium, heavy
and extremely heavy variations according to pollution severity. The appropriate
termination selection depends on the system voltage and operating environment.

Environmental
Performance
Material Characteristics
Hydrophobicity
When airborne contaminants are deposited on a termination surface, destructive
leakage currents can initiate when the surface becomes wet. Fog and drizzle are
normally considered to be worse than rain as these two forms of precipitation can
combine with accumulated surface contaminants to reduce surface resistivity
making the surface conductive to varying degrees, promoting leakage current
formation. Rain tends to wash the pollutants off the termination surface.
The inherent hydrophobic nature of the silicone rubber compound used to make
3M™ Cold Shrink QT-III Silicone Rubber Three-Conductor Cable Termination Kit
7600-3W Series, components tends to reject moisture accumulation, and thereby,
reduces the probability for discharge-initiated material erosion and tracking.
On occasion, severe environmental conditions that are sustained for long time
periods can cause any polymeric surface to lose its hydrophobicity. Because of
this, EPD polymers and others tend to lose their hydrophobic nature over time.
Porcelain surfaces become increasingly hydrophilic with time, which can result in
premature failure or flashover. Silicone surfaces can regenerate their hydrophobic
character. The silicone insulator surface will re-establish its hydrophobic surface
within 24 hours. This unique ability is a major factor for ensuring a long service life.
Ozone, Heat and UV Resistance
One of the most outstanding physical characteristics of silicone rubber is its
retention of desirable properties over the very wide temperature range of -150°F
(-100°C) to 600°F (315°C). While there are applications that take advantage of
these temperature extremes, a more attractive feature might be that of its extremely
long life expectancy at moderate operating temperatures.
The silicone polymer molecular backbone, silicone-oxygen linkage, provides the
same strong –Si-O-Si- type bond occurring in quartz, sand and glass, which
accounts for the outstanding temperature properties of silicones and their
resistance to oxidation by ozone, corona and weathering. Polymer chains from
organic rubber materials often have double carbon bond molecular backbones,
which are quickly cleaved by ozone, ultraviolet light, heat or other influences found
in the operating environment.

Critical performance characteristics for 3M™ Cold Shrink QT-III Silicone Rubber Three-Conductor Cable
Termination Kit, 7600-3W Series, includes resistance to damage from impulse flashover and from tracking during
long-term exposure to severe environmental conditions.
Impulse Flashover 3M Test Method – Maximum Impulse
The purpose of this test method is to establish both the maximum impulse withstand level
and the 100% impulse flashover level (on both positive and negative polarity) for high
voltage terminations.
A 1.2 x 50 microsecond voltage wave is applied to the termination lugs as per IEEE
Standard 48. Additional test standard references and procedures include those of IEEE
Standard 4, IEEE Standard Test Procedures and Requirements for Alternating Current
Cable Terminations 2.5 kV Through 765 kV and IEEE Standard 82, IEEE Standard Test
Procedure for Impulse Voltage Tests on Insulated Conductors.
To establish the insulating performance suitability of 3M™ Cold Shrink QT-III Silicone
Rubber Three-Conductor Cable Termination Kits, 7600-3W Series, phase re-jacketing
sleeve components, 15 kV Class termination samples were built in two configurations:
those with an exposed grounding ring at the termination base (control) and those without.
All specimens exceeded the IEEE Standard 48 BIL requirement by 50% during this test.
Increasing the impulse voltage to termination flashover level resulted in no damage to the
termination phase insulating re-jacketing components.

Dielectric Test
Performance
7600-3W Series termination kits are designed to conform to applicable international
standards (IEEE-48, CENELEC HD 629.1 S1 and VDE 0278). From extensive
performance testing in single phase configuration, it has been established that these
terminations meet, or exceed, the test requirements defined in these standards.
QT-III terminations pass pressure leak tests as described in Standard IEEE-48 in the single
conductor configuration and all 7600-3W Series termination components have
demonstrated the ability to provide a good moisture seal. Termination top and bottom seals
are tested by applying 7psi (0,05MPa) to the cable conductor strands with the termination
submerged in water. Both seals withstand this internal air pressure for 6 hours without
leaking.
Alternating Current
(AC) Flashover Test
3M Test Method – AC Step Test
The purpose of this test method is to establish the highest AC voltage that a termination
can withstand, and is used to determine if a termination will meet the minimum
performance requirements outlined in IEEE Standard 48.
Terminations are exposed to a stepped AC voltage rise to failure or flashover. The voltage
magnitude required to arc across the termination surface in air (from terminal lug to ground
point) is determined.
Individual 3/C 15 kV Class Termination phases that were tested with and without exposed
termination body grounding rings achieved test levels associated with 25 kV Class
products during this evaluation. Termination phase re-jacketing sleeves were not damaged
at flashover level.
Contamination
Chamber
3M Test Methods TM-402/ASTM 2132 Contaminant
Terminations are coated with a slurry consisting of flint, clay, paper pulp, salt and water and
allowed to dry. They are then placed in the test chamber where they are energized at 1.5
times rated voltage and exposed to a continuous water mist spray from a rotating nozzle.
Individual terminations are re-coated every 300 hours.
Because of the salt content and other solid particulate, this procedure is thought to be
representative of industrial-seacoast location exposures.
To determine the tracking performance capability of 7600-3W Series termination re-
jacketing sleeves, 15 kV Class termination specimens were built with grounding rings
located over the re-jacketing sleeves; eight and sixteen inches below the termination
bodies respectively.
Specimens exceeded 2500 hours under these test conditions. This duration equals, or
exceeds, the typical performance of 1/C conventionally grounded terminations. There
were no signs of re-jacketing sleeve material degradation, or tracking, at the conclusion of
the test.

Shelf Life &
Storage
As provided, in the expanded state, the 3M™ Cold Shrink QT-III Silicone Rubber
Termination Kits 7600-3W Series have a 3-year shelf life from date of manufacture when
stored in a humidity controlled storage (50°F/10°C to 80°F/27°C and <75% relative
humidity).
Maintenance It is good practice to incorporate a general inspection/cleaning of 3M™ Cold Shrink
QT-III Silicone Rubber terminations during normal scheduled shutdowns or maintenance
inspections. Once the area has been de-energized, the terminations can be inspected,
and if need be, cleaned. Some recommendations for surface cleaning 3M™ Cold
Shrink QT-III Silicone Rubber terminations are as follows;
Use a can of compressed ‘air’ in order to blast off dust and miscellaneous
airborne contaminants on the surface of the termination body. If needed, wipe the
surface of the termination with a cable cleaning solvent, such as 3M™ CC Series
Cable Cleaning Solvent (CC-2 Cable Cleaning Preparation Kit or CC-3 Cable
Cleaning Pad Kits), and allow it to dry before re-energizing the installation.
Mix a mild soap and water solution (deionized water is recommended, if available)
in a hand sprayer, or spray bottle, and spray down the surface of the termination.
Wipe dry, or allow to air dry, before re-energizing.
If tan discoloration between skirts is observed on the surface of the termination,
wipe with a cable cleaning solvent. The discoloration itself does not pose any
detrimental effect to the installation, and may not disappear entirely, but it will
lighten up to some degree. This discoloration a typical result of the outgassing
effect of EPR cable and does not interfere with the performance of the termination
in any capacity.
Do not abrade the surface of the termination in any way. Do not use high
pressure cleaning (this can tear, or split, the termination), high pressure water
with corn cobs, sandpaper or other abrasive products. This will damage the
termination surface and reduce tracking and arcing resistance.
