BS7870 Triplex Copper Power Cable 11kV - 11kV, XLPE, MDPE - 300mm²

Description

Copper MDPE Triplex 6.35/11 (12)kV cable is a medium voltage utility power cable constructed with Class 2 rigid stranded circular compacted plain copper conductors, cross-linked polyethylene (XLPE) insulation, a metal screen of concentric copper wires with helical tape, and a robust red medium density polyethylene (MDPE) outer sheath twisted together in a triplex formation. This highly durable cable is designed for use in utility power distribution, substation connections, renewable energy infrastructure, and underground direct burial or ducting systems.

The cables are manufactured to BS 7870-4.10 for distribution network operator polymeric insulated cables, alongside material quality benchmarks BS EN/IEC 60228 for rigid conductor properties. Featuring a standard rated voltage of 6.35/11kV, this cable provides dependable and safe power distribution for medium voltage electrical networks and utility infrastructure.

The cable should be installed with a minimum bending radius of 15 times the overall cable diameter during handling and routing. It is designed to operate within a core temperature range of 0°C to +90°C.
