Using bird-resistant insulators on high-voltage transmission lines

Ararat Wind Farm, Australia’s third largest wind farm, uses enhanced silicone polymer (ESP) insulators on the 132 kV powerline to reduce weight, improve speed of installation and increase span lengths. These insulators are also bird resistant which is critical because the powerline is located in a high bird strike zone. The Ararat wind farm, which […]

Protecting insulators from lightning damage

  Insulating joints (IJ) are used to electrically isolate pipeline systems or to isolate high-voltage-interference on pipelines into sections. Cathodically protected systems are electrically isolated until the dielectric strength of the insulating joint is breached. Surges caused by a lightning strike, into exposed parts of a pipeline system, may lead to the dielectric strength of […]
