Smart Medium Voltage Complete Switchgear
VGW-40.5 Indoor Medium-Voltage Vacuum Circuit Breaker (Spring-Operated)
Suitable for national power distribution networks, metallurgy, electrified railways, municipal construction, port construction, and other locations and supporting intelligent terminals, enabling power distribution automation applications.
Product Highlights
Internal partitioning can be flexibly adjusted according to specific requirements.
A busbar bridge can be installed on the top of the switchgear according to power receiving needs.
Uses vacuum arc extinguishing and epoxy resin encapsulated insulation, with excellent electrical performance.
Can be operated electrically/manually; integrated spring operating mechanism, convenient for operation and maintenance. Electrically and manually operable, with an integrated spring operating mechanism for convenient operation and maintenance.
Corrosion-resistant, fully sealed aviation connector design ensures high reliability of the power distribution automation interface, requiring long-term maintenance-free or minimal maintenance.
Integrated secondary control module with functions such as anti-burning of switching coils, anti-tripping, and undervoltage tripping.
