This document provides information on low voltage armoured underground cable and XLPE power cable. It describes the cable structures which include conductors, insulation, fillers, binders, sheaths and armour. It lists rated voltages, operating temperatures, conductor materials and shapes. Application details are provided for different cable types used for underground, indoor, and water/seabed laying. Key features of MV and LV XLPE cables are also summarized such as watertight construction, lead sheath option, and corrosion resistance.
Cables are often the last component considered during system design even if in many situations cables are the true system’s lifeline: if a cable fails, the entire system may stop. Cable reliability is therefore extremely important, then a cable system should be engineered to last the life of the system in the installation environment for the required application. Environments in which cable systems are being used are often challenging, as extreme temperatures, chemicals, abrasion, and extensive flexing. These variables have a direct impact on the materials used for cable insulation and jacketing as well as the construction of the cable. Using a systematic approach will help ensure that designer select the best cable for the required application in the installation environment. This lessons will provide students main guidelines for perform this approach.
The document discusses power cable technology, including:
1) The importance of cables for reliable power distribution and aesthetic reasons with growing load density.
2) The construction of different voltage cables, from LV to EHV, using materials like XLPE, PILC, and gas insulation.
3) Factors that determine cable ratings like soil conditions, depth of laying, and allowable operating temperature.
4) Best practices for cable laying including fixing routes, trenching, laying procedures, and post-laying inspections.
Underground cables have multiple components to safely transmit electricity over long distances. They consist of stranded copper or aluminum conductors for flexibility, insulation to isolate the conductors, and protective layers like a metallic sheath, bedding, armor, and serving. Cables are classified based on their voltage rating and can have single or multiple cores. Common cable types for 3-phase power distribution include belted cables, screened H-type and S.L. type cables, and high voltage pressure cables that use oil or gas to eliminate insulating voids. Proper cable construction and materials are needed to withstand mechanical stresses while safely conducting electricity underground.
Europacable is an association of European cable manufacturers that promotes the use of XLPE cables for electricity transmission. They believe XLPE cables are a reliable and innovative technology that have manageable environmental impacts and comparable life-cycle costs to overhead lines. Partial undergrounding using XLPE cables can facilitate grid extension by addressing local concerns and enable the integration of renewable energy sources into Europe's future energy mix.

Underground cable components include copper core cables approximately 150mm in diameter, made up of various insulating layers, housed in groups of three in trenches approximately 1.1m deep. Joints are required every 500-800m and sealing end compounds are needed at each end. Access and preparation requires a 65m working area cleared of vegetation with temporary fencing and trackways. Cables are laid by excavators in trenches reinforced with timber and surrounded by cement bound sand, then covered after jointing. Reinstatement returns the area to its original condition and inspection every 3 years monitors the cables.
DC testing has been accepted for many years as the standard field method for performing high-voltage tests on cable insulation systems. Whenever DC testing is performed, full consideration should be given to the fact that steady-state direct voltage creates within the insulation systems an electrical field determined by the geometry and conductance of the insulation, whereas under service conditions, alternating voltage creates an electric field determined chiefly by the geometry and dielectric constant (or capacitance) of the insulation.
Under ideal, homogeneously uniform insulation conditions, the mathematical formulas governing the steady-state stress distribution within the cable insulation are of the same form for DC and for AC, resulting incomparable relative values; however, should the cable insulation contain defects in which either the conductivity or the dielectric constant assume values significantly different from those in the bulk of the insulation,the electric stress distribution obtained with direct voltage will no longer correspond to that obtained with alternating voltage.

A Comparative Evaluation of Copper and Aluminium Wires and Cables in Building...Leonardo ENERGY
This document provides a comparative evaluation of copper and aluminium wires and cables used in building installations. It examines the physical properties of each material and compares their conductivity, current carrying capacity, weight, strength, installation characteristics, reliability of connections, susceptibility to corrosion, and relative costs. Copper is found to outperform aluminium in each category due to its higher conductivity, strength, resistance to creep and cold flow, smaller size for equivalent ampacity, and more reliable connections. While aluminium cables impose similar loads on buildings as copper, they require larger containment sizes due to their larger diameter and bending radii for an equivalent current capacity. The document concludes that copper remains the superior conductor material for wires and cables used in building power systems.
Copper and aluminum are common materials used for electrical conductors. Copper is a better conductor but aluminum is lighter weight and cheaper. Different types of wires include PVC-coated wires, which are durable, long-lasting, and resistant to water, heat, oil and UV light. Conductors with higher resistance, like tungsten and nichrome, are sometimes used to convert electrical energy into heat, light, and sound. The size and type of wire or cable must match the power rating required for safe use, as supplying too much current can cause overheating and damage insulation, potentially resulting in a short circuit.

Understanding User Needs and Satisfying ThemAggregage
https://www.productmanagementtoday.com/frs/26903918/understanding-user-needs-and-satisfying-them
We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
• Highlight the crucial benchmarks, observable changes, in ensuring fulfillment of customer needs
