SF6 Column Circuit Breaker VGP-110

The VGP-110 SF6 column circuit breakers have been produced since 2006. These breakers consist of three poles (columns) with arc-quenching chambers in porcelain insulators, mounted on a galvanized frame with a spring-operated mechanism. The breakers are simple and reliable in operation. Additional features include a maintenance platform, control cabinet, and a digital control and monitoring system (IEC 61850).

The arc-quenching device is located in the upper insulating column filled with SF6 gas. The mechanism connects via high-strength fiberglass rods by Tyco. The poles are mounted on a galvanized steel frame. The spring mechanism is housed within protected cavities, providing additional resistance to environmental and mechanical impacts. The drive motors can operate on both AC and DC power and are equipped with necessary interlocks. The breaker includes gas density monitors from leading European manufacturers like WIKA and Trafag.
