The 126KV Outdoor high-voltage SF6 open type combination electrical appliances stands out as an integrated electrical device specifically designed for high-voltage power transmission and distribution systems. Its unique composition includes circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, and surge arresters, all enclosed in a metal housing filled with sulfur hexafluoride (SF6) gas, a highly effective insulating medium.

The 126KV 1600A Outdoor high-voltage SF6 tank circuit breaker is a sophisticated electrical switching solution designed to safely disconnect high-voltage electrical paths in emergency situations or for regular maintenance. It employs sulfur hexafluoride (SF6) gas as a fire-suppressing and insulating agent, housed within a hermetically sealed container. This particular type of circuit breaker is purpose-built for exterior installation in electrical substations and power distribution systems.

126KV Outdoor high-voltage SF6 ceramic column circuit breaker is a high-voltage sulfur hexafluoride device used in outdoor electrical systems operating at 126kV. It is designed to manage and safeguard power transmission and transformation networks. This breaker can serve as a switch and disconnection unit when needed. The breaker's innovative arc extinguishing technique involves thermal expansion and auxiliary blowing, and it incorporates a CTB-1 operating mechanism. It complies with the GB1984-2003 standard for AC High Voltage Circuit Breakers and ful specifications of the IEC62271-100:2001 standard for High Voltage Switchgear and Control Equipment Part 100: High Voltage AC Circuit Breakers established by the International Electrotechnical Commission.

LW8-35 36KV 3150A Outdoor HV SF6 Circuit Breaker is applicable for outdoor 50Hz three-phase HV electric equipment and control & protection of 36kV power distribution & transmission system, as well as measurement and protection via the breaker enclosed current transformer. Breaker is also used for interconnected circuit breakers and switching capacitor banks.

The 145KV Outdoor high-voltage SF6 open type combination electrical appliances stands out as an integrated electrical device specifically designed for high-voltage power transmission and distribution systems. Its unique composition includes circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, and surge arresters, all enclosed in a metal housing filled with sulfur hexafluoride (SF6) gas, a highly effective insulating medium.

Negli ultimi anni, poiché la società e l’economia hanno continuato ad evolversi, il settore dell’ingegneria delle costruzioni è diventato più complesso a causa dei progressi tecnologici. Vi è una crescente preferenza per apparecchiature di commutazione compatte, che richiedono una manutenzione minima e sono intelligenti. Sia i produttori di interruttori locali che quelli internazionali stanno lavorando attivamente su quadri elettrici per armadi gonfiabili a media tensione da 12 KV 250 A (C-GIS) o quadri isolati in gas. Questa tecnologia prevede la chiusura di componenti ad alta tensione come sbarre collettrici, interruttori automatici, sezionatori e cavi di alimentazione all'interno di un involucro con pressione del gas ridotta.
