Panel Wire
What is Panel Wiring?
Panel Wire is a general term that can be applied to a number of different cables. When people talk about this high temperature, flame retardant and flexible single core cable they may, for example, be referring to Tri-rated Cable – also commonly known as BS6231 Cable – or 2491B/6701B Cable (a LS0H single core cable). By meeting the requirements of three national standards, Tri-rated Cable reduces inventory costs and makes purchasing simple. The LS0H equivalent 2491B/6701B Panel Wire is also a suitable cable for those working with control equipment in public buildings.
Flexible (Class 5) copper cables – with either PVC or LS0H 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, building and construction to marine and defence, and transmission, 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 three different standards: BS6231 Type CK, UL (or Underwriters Laboratories) Subject 758 Appliance Wiring Materials (AWM) for styles 1015, 1028, 1283, and 1284 as applicable and CSA (Canadian Standards Association) Standard C22.2, No.127, Type TEW. The flexible 2491B/6701B Cable, on the other hand, meets the requirements of BS7211, HD22.9 and IEC60332-3-24 standards.
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).
