COMPANY PROFILE<\/span><\/p>\n

High Voltage Sf6 Circuit Breaker<\/h1>\n

Subian Electric manufactures high voltage equipment including SF6 circuit breakers at our factory in Xuzhou, Jiangsu, China. SF6 circuit breakers are the standard protection device for outdoor HV substations from the 40.5kV class up to 126kV, using sulphur hexafluoride gas for insulation and arc extinction.
\nAssembled and tested in our 50,000-square-metre facility, each breaker is delivered with type-test evidence, drawings and commissioning support from our 350+ staff, who have supplied projects in more than 50 countries since 2019.
\nSend your system voltage, short-circuit level and substation layout, and our engineers will confirm the breaker specification and factory quotation.<\/p>\n
