Hda Conductor 100mm2
The Aluminum conductor shall be manufactured to BS 215. Shall be concentrically stranded,with successive layers in opposite lay, but such that the outermost layer shall be in the right hand spiral(Z).
The wires in each layer shall be evenly and closely stranded. the complete conductor and its layers shall be firm and solid. the lay ratio shall not exceed 13.
In conductor having multiple layers of wires. the lay ratio of any layer shall be not greater than the lay ratio of the layer immediately beneath it. No grease shall be applied to the conductor.
PVC covered conductor according to BS6485
The material ,construction and physical properties of the conductor shall,after covering, conform to BS215
