15 - 38 kV HV Capacitor Bank - Power factor switching

VersaVac switch

The VersaVac (VSV) is a long life vacuum switch used for pole top Capacitor switching.

The VSV was specifically designed to replace oil switches to eliminate costly maintenance.

The VSV can be used as a direct replacement on existing banks or supplied by manufacturers on new banks. Joslyn's unique design incorporates Joslyteš , the field proven solid dielectric foam that has been successfully used over 35 years.
