PVC, PE or HFFR sheathed cables for BUS and Interface Systems
1. Application
RS-232, RS-422, RS-485, KNX (EIB or Instabus), LonWorks, ModBus, M-Bus, CAN-bus, BACnet, BMS (Building Management
Systems) or general interface systems.
2. Basic Construction of the cables
Wire = conductor without or with insulation. With insulation sometimes also indicated as core.
Conductor: may be solid = one single rod or flexible = twisted bare or tinned copper strands, ranging from 12 to 24AWG.

14 19 x 27 19 x 0.36 ≤ 9.36
12 19 x 25 19 x 0.45 ≤ 5.61
Insulation: Polyethylene (PE) or Foam PE (FPE) for PVC (Polyvinyl Chloride) or Halogen-Free (HFFR) sheathed cables. And
Halogen-Free (HFFR) for HFFR sheathed cables. All insulations are in accordance with BS EN 50290-2, good strippable and
coloured. The colours are not interchangeable.
Pair = two twisted – colour coded – wires.
Individually screened pair (if applicable): one pair wrapped with an Aluminium/Polyester foil under which a drain wire.
Cable core: two or more (individually screened) pairs stranded.
Good twisting (lay-length < 30 ~ 40D) is necessary otherwise the cable can hardly be bending and will break after a few bends.
Drain wire (only in combination with a screen): stranded tinned copper wires. In order to avoid corrosion, it is recommended that
drain wires are tinned.
Screen (if applicable): Helically applied (= as a spiral) Aluminium/Polyester (Alpet) foil. For the flexibility of a cable a helically
applied foil is to be preferred. A longitudinally applied foil act more as a stiff tube = more difficult to bend.
Braiding (if applicable): tinned copper wires.
Sheath: grey PVC , black PE or purple HFFR, all in accordance with BS EN 50290-2.

KNX is a standardised (EN 50090, ISO/IEC 14543), OSI-based network communications protocol for intelligent buildings. KNX is
the successor to, and convergence of, three previous standards: the European Home Systems Protocol (EHS), BatiBUS, and the
European Installation Bus (EIB or Instabus).
BT Cables main part numbers for KNX cables: C1217 (quad – PVC) – C1218 (quad – HFFR) – C1219 (1 pair – PVC) – C1220 (1
pair – HFFR).
LonWorks is a networking platform specifically created to address the needs of control applications. The platform is built on a
protocol created by Echelon Corporation for networking devices over media such as twisted pair, power lines, fibre optics, and
RF. It is used for the automation of various functions within buildings such as lighting and HVAC.
BT Cables main part numbers for LonWorks: C1198 (PVC) - C1203 (PVC) – C1307 (HFFR) – C1271 (HFFR) –

Application and Construction
1. Application
All PVC and HFFR sheathed multi-conductor cables are suitable for Building Management Systems (BMS), Sound, Audio,
Security, Safety, Control and Instrumentation.
Wire = Conductor without or with insulation. With insulation sometimes also indicated as core.
Conductor: flexible = twisted bare or tinned copper strands, ranging from 12 to 22AWG.

14 19 x 27 19 x 0.36 ≤ 9.36
12 19 x 25 19 x 0.45 ≤ 5.61
Insulation: Polypropylene (PP) for PVC (Polyvinyl Chloride) sheathed cables and Halogen-Free (HFFR) for HFFR sheathed cables.
Both insulations are in accordance with BS EN 50290-2. Good strippable and coloured insulation. The colours are not
interchangeable.
Colour scheme of wires with 12 or 14 AWG conductors: black-white-red-green-brown-blue-orange-yellow-purlpe-grey-pink-
tan.
Colour scheme of wires with ≥ 16AWG conductors: black-red-white-green-brown-blue-orange-yellow-purlpe-grey-pink-tan.
Cable core: two or more wires, twisted.
Good twisting (lay-length < 30 – 40D) is necessary otherwise the cable can hardly be bending and will break after a few bends.
Drain wire (only in combination with a screen): stranded tinned copper wires. In order to avoid corrosion, it is recommended that
drain wires are tinned.
Sheath: grey PVC or purple HFFR or black UV-resistant HFFR, all in accordance with BS EN 50290-2.

Section 5 - BT Security-Tec ™– Coaxial Cables
Application and Construction of Coax Cables for 75 Ohm Video Systems
Applications.
CCTV: Closed Circuit Television is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors
SMATV: Satellite Master Antenna Television used to deliver signals to multiple dwelling units (e.g., apartment buildings and
trailer parks).
CATV: Central Antenna Television = Cable television is a system of providing television to consumers via radio frequency signals
transmitted to televisions. Nowadays also used for internet and telephone.
HDTV: High-definition television refers to video having resolution substantially higher than traditional television systems.
Telecom and networking: a number of special cable constructions.
Basic Cable Design.
Coaxial cables are designed to carry radio frequency current of a much higher frequency than the 50 or 60 Hz used in
low voltage cables. And this requires special construction to prevent power losses. If an ordinary wire is used to carry
high frequency currents, the wire acts as an antenna, and the high frequency currents radiate off the wire as radio
waves, causing power losses. To prevent this, in coaxial cable one of the conductors is formed into a tube and encloses
the other conductor. This confines the radio waves from the central conductor to the space inside the tube. To prevent
the outer conductor, or shield, from radiating, it is connected to electrical ground, keeping it at a constant potential.
The dimensions and spacing of the conductors must be uniform throughout the length of the cable. Any abrupt change
in the spacing of the two conductors along the cable tends to reflect radio frequency power back toward the source.
This acts as a bottleneck, reducing the amount of power reaching the destination end of the cable.
Choosing the correct 75 ohm coax cable.
Most coaxial cables for video applications have a nominal impedance of 75 ohms. Their differing electrical and physical
characteristics make it important to select the correct type of cable to suit the application.

All conductors in BT Cables are in accordance with above tables unless otherwise stated in the respective section of this
publication or datasheets.


Pairs: all pairs consist of two twisted wires with a lay-length < 40 D.
Cable Cores: all cable cores consist of stranded wires or pairs
Foil screens for multi-core and multi-pair cables, screens or shields mostly consist of an aluminium foil laminated to polyester, broadly
known as Alpet. These foils are helically (as a spiral) applied with sufficient overlap to guarantee 115 % or more coverage. . For the
flexibility of a cable a helically applied foil is to be preferred. A longitudinally applied foil act more as a stiff tube = more difficult to bend.
A drain wire or continuity wire, contacting the aluminium side of the foil, is used for the termination of the screen and also to ground
electrostatic discharges.
In case the screen of a coaxial cable where the screen may be a foil, this foil will be applied longitudinally and will also be bonded to the
dielectric around the conductor.
Braided screens consist of 16 or 24 groups of strands. One set of 8 or 12 strands is woven clockwise and the other set of 8 or 12 strands
anti-clockwise. Strands can consist of tinned or bare copper or aluminium wires.
Braided screens provide good screening efficiency and flexibility. Higher coverage provides better screening.
Sheaths: grey PVC, purple HFFR or black for PE, all in accordance with BS EN 50290-2.

CE Marking
The CE marking certifies that a product has met EU
consumer safety, health or environmental
requirements. By affixing the CE marking to a
product, the manufacturer – on his sole responsibility
– declares that it meets EU safety, health and
environmental requirements or, if stipulated in the
directive(s), it had to be examined by a notified
conformity assessment body.
Quality assurance
UL Approval / Listing
UL does not approve products. Rather it evaluates
products for compliance to specific requirements, and
permits acceptable products to carry a UL certification
mark, as long as they remain compliant with the
standards.
Products under its listing service are said to be “UL
Listed,” identified by the distinctive UL mark.
