Bare Copper Conductor

Feature
The conductors are applied for overhead power transmission purposes.

CONSTRUCTION

Conductor
Seven or more copper wires the same nominal diameter are twisted together in concentric layers. When conductor consists of more than one layer, alternate layers are twisted in opposite directions which is defined as right-hand lay (Z) or left-hand lay (S).

Bare Copper Conductor - Hard (BCC-H)
The conductor has mechanic characteristic minimum 428 N/mm². The maximum resistivity at 20° C is 0.01786 ohm. mm²/m.

Bare Copper Conductor - Half Hard (BCC-1/2H)
The conductor has mechanic characteristic between minimum 340 N/mm². Maximum 410 N/mm². The maximum resistivity at 20° C is 0.01784 ohm.mm²/m.

Annealed Copper Wire (BCC Soft)
The conductor has maximum resistivity at 20° C is 0.017241 ohm.mm²/m.
