What is BS6346 Traffic Signal Cable?
BS6346 Traffic Signal Cable is a 0.6/1kV multi-core Class 1 solid copper conductor PVC insulated steel wire armoured control cable manufactured in accordance with BS 6346 and BS 50363 standards. Designed specifically for municipal traffic management systems, it provides multi-core signal interconnection with high mechanical endurance.
The cable features Class 1 solid annealed copper conductors, PVC insulation, a polymeric bedding layer with minimum 4N/mm² tensile strength, a single layer of galvanized steel wire armour (SWA), and a high-visibility orange PVC outer sheath. Its multi-core configuration (ranging from 8 to 20 cores) enables complex signaling and control interconnectivity in demanding outdoor and underground operating environments.
BS6346 Traffic Signal Cable Construction
- Conductor: Class 1 solid annealed copper conductor
- Insulation: PVC (Polyvinyl Chloride)
- Bedding: Polymeric compound with tensile strength ≥ 4N/mm² and elongation at break ≥ 50%
- Armour: Single layer of galvanized steel wires laid in a right direction (SWA)
- Outer Sheath: PVC (Polyvinyl Chloride)
- Core Identification: Distinctive multi-layer color scheme (8, 12, 16, and 20 cores featuring solid and bi-color combinations including Brown, Yellow, Green/Blue, Red, White, Blue, Black, Orange, Grey, Violet, etc.)
- Sheath Colour: Orange
Applications
Traffic Signal Cable BS 6346 SWA PVC is engineered for interconnecting traffic control equipment, road junction signaling, and industrial control systems requiring high core-count configurations with physical protection. Key application environments include:
- Interconnection of municipal traffic signal equipment and road junction controllers
- Direct underground burial in municipal roadways, sidewalks, and traffic trenches
- Installation in cable ducting, subterranean conduits, and roadside enclosures
- High-density auxiliary control and signaling networks in industrial sites

Frequently Asked Questions
Q: Why does BS 6346 Traffic Signal Cable use an orange outer sheath?
A: The high-visibility orange PVC outer sheath is standard for traffic signal infrastructure, allowing clear identification in underground cable ducts and utility trenches to prevent accidental damage during roadwork.
Q: Can BS 6346 Traffic Signal Cable be directly buried underground?
A: Yes, the galvanized steel wire armour (SWA) layer provides strong mechanical resistance against crushing, impact, and physical strain, making it fully suitable for direct burial in soil.
Q: What conductor sizes and core counts are available for this cable?
A: BS 6346 traffic signal cable is available in 1mm² and 1.5mm² Class 1 solid copper conductors, with standard core configurations of 8, 12, 16, and 20 cores.
Q: What is the standard production lead time?
A: Our standard production lead time ranges from 15 to 25 working days, depending on core count, total volume, and drum packaging specifications.
