Part 36 Mining

Section 567 Overhead power lines

Cables between overhead power lines and moveable switch houses, or between an overhead power line and a substation, must be continuous, without couplers or junction boxes. In addition, the supply cable must not exceed a length of 25 metres unless the noted conditions are met.

At the overhead line end of the cable, a separate means of disconnection must be located on the power pole. Such a disconnect system can use “cut-outs” on a pole or be of some other design, subject to approval by the Director.

To minimize the risk of injury to workers, cable connections to moveable switch houses or substations must be directly through suitable cable glands.
