General Notes
Clearances of conductors from ground, other structures and other conductors shall be undertaken in accordance with the current ESAA C(b)1 Guidelines for design and maintenance of overhead distribution and transmission lines, and Western Power reference, Distribution Design Manual Vol 5 Overhead Bare Conductor.
The low voltage neutral shall be continuous at all times, including where low voltage isolation is provided as indicated in drawing L6 and terminations as shown in L3.
All aerial connections shall be undertaken by mechanical means, hand splicing is not acceptable. Any in-line service extensions shall match the existing conductor size unless otherwise rated for connected load.
All poles supporting transposed open aerial conductors must be identified. Two approved ‘LV Transposed’ signs must be attached on the roadside of the pole; one at approximately two metres above ground level and the other just below the crossarm. The approved sign displays four horizontal bands of black, white, black, white from top to bottom with the words ‘LV Transposed’ in red lettering.
Note: A transposed sign may also indicate incorrect phase positions.
Low Voltage Spreaders
All LV spreader requirements shall be as detailed in the construction design. Even separation along the conductor bay shall be maintained for LV spreaders. A three by 2-wire spreader arrangement is deemed as one spreader
All LV spreaders are to be installed with the relevant Works Practice Instruction.
