Overview

Heavy wetting flashover may occur during live-line washing or torrential rain.  A large volume of polluted water flowing down one side of an insulator can bridge much of the leakage distance. It occurs predominantly on large bushings and post insulators where the sheds are closely spaced and are all the same diameter.

Icing flashover occurs when there is heavy snow or ice build up on the insulator skirts. When the temperature starts to rise above freezing, the melting droplets start a stream of water that can induce a flashover.

The booster shed breaks up long cascades of lightly contaminated water. HVBS cools, compresses and extinguishes discharges which run between it and the porcelain insulator. It also acts as an arc-chute or expulsion tube to eject heavy current arcs from its underside.

Superior high-voltage outdoor materials are used in the Booster Shed design. The rugged, non-tracking, UV-resistant, high temperature polymer ensures long-term performance even in the most extreme environmental conditions.
