Advance Power Solution

11KV Vaccum Interruptor make ABB, Siemens, Schneider as per customer required. vacuum interrupters feature an evacuated ceramic insulating envelope surrounding two contacts, one fixed and one movable.
The movable contact is operated from the outside through a metallic bellows. Contacts are typically a copper alloy that is developed for use in AC voltage applications. The end plates are made of stainless steel or copper.
Long life, high reliability — Vacuum interrupters can be expected to last the life of the equipment in which they are installed.
Controlled contact erosion results in virtually maintenance-free operation.
Fast interrupting speed — The interruption mechanism is independent of current magnitude, so interruption can normally be anticipated at the first current zero with no restriking.
Rapid dielectric recovery — The dielectric strength of the contact gap recovers more rapidly than the recovery voltage can rise, eliminating restriking.
Robust, compact design — Vacuum dielectric enables contacts to be arranged close together so circuit interruptions can be designed in a smaller envelope
