XGN17-40.5 Box-type Fixed AC Metal Switchgear

Product Overview

It is used for receiving and distributing electric energy in 40.5 three-phase AC 50Hz system, mainly applied to power plants, substations, industrial and mining enterprises and institutions, etc. It is particularly suitable for frequent operation places, and can be derived from single bus with bypass and double bus structures. The circuit breaker can be equipped with domestic ZN12-40.5 or ZN23-40.5 vacuum circuit breaker, and can also be equipped with ZN85 fixed circuit breaker, which is fixed and equipped with CD10 series electromagnetic or CT19 series spring operating mechanism, and the isolating switch adopts GN27 series products.

Product Characteristics

• The cabinet structure is welded with high-quality steel plate and angle steel.
• It has independent circuit breaker chamber, bus chamber and cable chamber.
• It adopts a mechanical disc operating mechanism, with reliable "five antis" performance.
• Good anti-condensation frost and anti-fouling performance.
