Capacitor vacuum switches PS

Vacuum switch solution for switching medium-voltage capacitors

The PS vacuum switch is a solid dielectric vacuum switch suitable for use in distribution systems up to 38 kV ungrounded. The switch has been specifically designed and tested in accordance with ANSI C37.66 for heavy-duty operation in capacitor-switching applications for the harshest climatic conditions.

The PS15, PS17and PS25 make up the single phase switch range, while the PS36 is a complete three phase switch.

The PS capacitor vacuum switch is designed to reduce lifecycle costs and offer customers true value.

Applications

The PS range of capacitor switches are designed for use in capacitor switching applications. They may be used in metal enclosed capacitor banks, outdoor rack banks, or pole top banks (e.g., QPole).

Why Hitachi Energy?
