Bare Copper Conductor

Product Description

Bare Copper Conductor

Basic design to BS 6360 and BS EN 60228 / IEC 60228

Features And Benefits

Stranded bare soft or annealed copper conductors are suitable for direct burial and do not suffer from the inherent corrosion problems that an aluminum conductor would. Copper is almost twice as conductive as aluminum. Copper is easier than aluminum to terminate and join at splices and joints.

Construction

Bare copper conductors are compressed concentric-lay-stranded consisting of one or more layers of wire wrapped helically around a straight round central wire. Each successive layer has six wires more than the layer immediately beneath. Greater flexibility is afforded by using Class 2 stranding. The direction of lay for the outer layer is left hand lay. In 7,19 and 37 wire constructions, the direction of lay of each successive layer is reversed.
