VGK400-12 Miniaturized digital switchgear

Summary

VGK400-12 is a removable vertical spinning intelligent cabinet made of green and low-carbon materials. The core vacuum circuit breaker and double disconnectors are arranged longitudinally on a handcart-style frame. The disconnectors' operating mechanism allows for both electric and manual operation. This product is recommended by the State Grid and China Southern Grid as a new generation of green and low-carbon products. The product incorporates multiple sensing units to meet real-time monitoring of its current-carrying, mechanical, insulation, environmental, and other states. It also uses edge technology to achieve self-inspection of the device's health status and provide timely warning of faults.
