What is Panel Wiring?
Panel wiring refers to a number of different cables that are used within control panel applications. Panel wire variations include:
Tri-rated Cable – a high temperature, flame retardant, single core PVC flexible cable, also commonly known as BS6231 Cable or H07V2-K. Tri-rated Cable meets three national quality standards: UL, BSI and CSA, which in turn meets an internationally recognised requirement.
2491B/6701B– LSZH single core flexible cable which produces no corrosive gases under fire conditions, making it ideal for electronic equipment installations and public buildings.
2491X PVC Flexible Cables– also known as H05V-K H07V-K cable which is made to quality standards BS6004 and CENELEC HD21.3
Coil End Lead – cable with EPR-HOFR insulation for resistance against oil and heat. Made to quality standard BS6195 Type 4.
Flexible (Class 5) copper cables with either PVC or LSZH insulation work well as internal connectors in controllers, motor starters and rectifier equipment, and are suitable for use in switch control, relay and instrumentation panels.
Which industries use Panel Wire?
Panel wire can be used in everything from control panel manufacturing, automation and process control, and building and construction, to marine and defence, distribution and power networks.
Panel Wire meets the requirements of which standards?
The most common panel wire is Tri-rated Cable, which is manufactured to the following three standards: BS6231 Type CK, UL Subject 758 Appliance Wiring Materials (AWM) and Canadian Standards Association (CSA). 2491B/6701B meets the requirements of BS7211 Table 3 & 4b, CENELEC HD22.9, BS EN 50525-3-41, IEC 60332-3-24, IEC 60754-1 & 2 BS EN 50267-2-1 & 2, andBS EN / IEC 61034-1. 2491X meets the requirements of BS6004 and CENELEC HD21.3. Coil End Lead meets the requirements of BS6195 Type 4 Gasses.
What is the maximum conductor operating temperature of Panel Wire?
Extensive physical testing of the insulation at high temperatures means Panel Wire can stand the heat. Both BS6231 (Tri-rated) and BS7211 state that the cable should have a maximum operating temperature of 90°C for continuous use. In the case of Tri-rated Cable, UL and CSA standards identify the maximum operating temperature of Panel Wire as 105°C, but this refers to its operating temperature over a period of 15,000 hours.
Is Panel Wire easily identifiable by the colour of its sheath, insulation or outer surface?
Panel Wire comes in a whole variety of different colours from black, red, blue, yellow, green/yellow, grey, brown, orange and white to violet, green, pink, light blue and dark blue. This offers some flexibility to equipment manufacturers and panel builders. In certain circumstances, however, the cables will be subject to core colour requirements set down in other standards such as BS7671.
Is Panel Wire the only cable used in panels?
Those working on panels will come into contact with a range of different cables – both in the panel (such as the flexible Coil End Lead Cable and 0361TQ Welding Cable) and connected to it (such as SWA and Control Cables – SY Cable, CY Cable and YY Cable).
