SYHF is a professional supplier of gas insulated switchgears. Our SF6 insulated ring main unit switchgears are consist of circuit breakers, isolating switches, grounding switches, and busbars, all enclosed in airtight compartments filled with SF6 gas. This design aims to optimize space utilization while making high levels of electrical insulation and current carrying capacity. The design purpose of a circuit breaker is to interrupt current during faults or normal switching operations. They use SF6 gas with excellent dielectric properties. Gas is stored at a certain pressure inside the switchgear, and the components are designed to withstand high voltage and current.

SYHF's high qualified 11kV SF6 GIS gas insulated Switchgear is designed for underground transmission lines with voltage levels of 17.5kV and 24kV. It consists of a load circuit breaker (LBS) and a circuit breaker (CB) or fuse switch module, which varies according to customer requirements. The operating mechanism is CB spring charging with vacuum circuit breaker, and the SW and fuse switches are spring operated. The minimum number of parts in the organization can achieve long-lasting service, thereby improving cost-effectiveness.
