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 onfigurations 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
