The 72.5KV 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 40.5KV 1600A Outdoor high-voltage combination electrical appliances, an outdoor high-voltage electrical appliance, is an efficient solution that combines air insulation with SF6 gas for arc extinguishing. This unit is designed for controlling and protecting three-phase AC 40.5kV transmission and distribution systems, as well as for connecting circuit breakers and operating capacitor banks. Its efficiency makes it ideal for use in urban substations, enterprise substations, and mountain substations with limited land availability, promising to improve your operations.

The 40.5KV 1600A Outdoor high-voltage SF6 tank circuit breaker is a customized electrical switchgear designed to disconnect high-voltage electrical paths in emergency situations or for scheduled maintenance. It employs sulfur hexafluoride (SF6) gas as the medium to extinguish electrical arcs and provide insulation, which is safely confined within a sealed enclosure. This particular type of circuit breaker is purposely designed for exterior deployment in electrical substations and power transmission systems.

12KV Indoor Medium Voltage Vacuum Circuit Breaker is a high-voltage solution for indoor applications, featuring a rated voltage of 12KV and a frequency of 50Hz for three-phase AC systems. This product, known for its reliability, complies with the GB1984-89 standard. The design of this product is available in two configurations: the switch body and operating mechanism are integrated, and a modular version where the switch body and operating mechanism are separate. The integrated design is denoted as the ZN28-12 type, while the modular design is referred to as the-12 type, suitable for use in fixed switches such as GG-1A(Z) and XGN2A10(Z). This product can be paired with DC electromagnetic types CD17 and CD10A, as well as spring energy storage types CT17 and CT19.

In recent years, the engineering construction landscape has evolved in response to societal, economic, and technological advancements. There is an increasing demand for compact, intelligent, and low-maintenance switch equipment. Domestic and international manufacturers are actively developing 40.5KV 3150A Medium Voltage Gis Gas Insulated Switchgear (C-GIS), which enclose high-voltage components like busbars, circuit breakers, isolating switches, and power cables within a pressure-reduced shell.

The ZW32 series 12kv ourdoor mv vcb vacuum circuit breaker, a versatile and reliable piece of equipment, is designed with the user's convenience in mind. With a rated voltage of 12kV and a three-phase alternating current of 50Hz, it efficiently opens and closes load current, overload current, and short circuit current in power systems. Its suitability extends to power distribution systems in substations, industrial and mining enterprises, and rural areas where the power grid is frequently operated. This circuit breaker's unique selling points include a compact design, lightweight construction, and anti-condensation properties. However, its most appealing feature is its low maintenance requirements, making it a cost-effective solution for your power distribution needs.
