Variable voltage 33KV ,36KV, 40.5KV plug-in type air filled / SF6 gas Vacuum Circuit Breaker 2000A,1600A, 1250A. Baoding Zhongyi Electrical Material Manufacturing Co., Ltd. US $299.00-$899.00 / Set

C. It is filled by buffer gasification during air filling (it can be heated). (3) operating environment temperature: -10℃(-30 optional)--- +40℃ (4) Main performance and technical parameters. 1,The ultimate vacuum of the device. 2,Vacuum pumping rate of the device is 55m3/h (vacuum pump limit is less than 0.06Pa)

2018-3-13The equipment is safe, maintenance-free, compact, light-weighted and long life expectation on mechanical operation. The circuit breaker is enclosed in SF6 filled or N2 filled mental enclosure which is condensation and humidity resistance, suitable for high temperature and humidity application.

2019-6-5• Vacuum interruption in an SF6 filled, controlled environment (0.5 bar gauge) • Dead tank construction suitable for live or dead tank applications • Internal arc containment • Generous accommodation for current transformers • The lightweight aluminium tank makes the Horizon easier to transport and install

2018-8-29Today, the SF6 and vacuum circuit-breakers made use of the same operating mechanisms, so in this regard they can be considered identical. However, in relation to their interrupters the two circuit breakers exhibit a marked difference. The number of moving parts is higher for the SF6 circuit-breaker than that for the vacuum

2020-3-31CBGS-0 SF6 circuit breaker switchgear Ratings/features • Up to 38 kV, 2,000 A, 31.5 kA, and 150 kV BIL • Compact design 24” W for mains/feeders and 48” W for tie • Fixed vacuum or SF6 circuit breaker • Solid insulated and shielded bus bar system • Internal arc tested 31.5 kA/1 s per IEC 62271-200

2020-11-30Vacuum technology. Although SF6 is non-toxic and non-flammable on its own, when used as a circuit-interrupting medium it can produce a number of dangerous and toxic decomposition products. This calls for special precautions when working on any SF6-filled equipment. Even more serious is the issue of disposal at
