British Standard Highway Cables

Traffic Signal Cable to BS 6346

Application and Description :

Traffic signal cable is used for the interconnection of traffic signal equipment or other applications
requiring high core configurations with mechanical robustness.

Standard and Approval:

BS 6346, BS 6360, BS 7655

Cable Construction:

- Conductor: Solid plain annealed copper, comply with BS 6360, Class 1
- Insulation: Polyvinyl chloride (PVC), TI1, comply with BS 7655
- Bedding(for Armoured Cable Only): Polyvinyl chloride (PVC) compound
- Armor(for Armoured Cable Only): Galvanized steel wire armor
- Sheath: Polyvinyl chloride (PVC), TM1, comply with BS7655
- Sheath color: Orange

Core Identification :

4 core - Red, Blue, Yellow, Green
8 core - Brown, Yellow, Green, Red, White, Blue, Black, Orange
12 core - Brown, Yellow, Green, Red, White, Blue, Black, Orange, Red/White, Grey, Red/Blue, Violet
16 core - Brown, Yellow, Green, Red, White, Blue, Black, Orange, Red/White, Grey, Red/Blue, Violet,
