General Notes
Clearances of conductors from ground, other structures and other conductors shall be undertaken in accordance with AS/NZS 7000:2010, Standard for Overhead Line Design – Detailed Procedures, and the following Western Power references:
Distribution Overhead Line Design Manual
High Voltage Aerial Bundled Cable Manual
High Voltage Hendrix Manual
HV Insulated Taps are to be used where wildlife protection against contact with earth or another phase is required, using either –
1) LVABC may be used for connection to for mounted transformers and cable heads supplying ground mounted transformers,
2) For all other applications, use a conductor to match the conductors being joined, and fit this conductor with grey flexible hose with drain holes cut at the bottom of the drip loops to drain moisture.
