China Heavy-duty outdoor HV isolating switch Manufacturer, Supplier, Factory

The 35kv European type Outdoor prefabricated Substation is widely used in urban power grid renovation, residential communities, high-rise buildings, industrial and mining, hotels, shopping malls, airports, railways, oil fields, docks, highways, and temporary electrical facilities, both indoors and outdoors.

In recent years, engineering construction has become increasingly complex as society, the economy, and technology have advanced. There is a growing demand for compact switch equipment that requires minimal maintenance and is intelligent. Domestic and international switch manufacturing companies are actively developing the 35KV 3150A Medium Voltage Gas Insulated Electrical Switchgear, also known as gas-insulated switchgear (C-GIS), which encases high-voltage components like busbars, circuit breakers, isolating switches, and power cables within a pressure-reduced shell.

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 KYN28-12(Z) AC metal armored switchgear 3.6KV 3150A Medium Voltage High Current Electrical Switchgear is designed for three-phase AC power systems with a rated voltage of 12kV and a rated frequency of 50Hz. It serves as a reliable and efficient solution for receiving, distributing, controlling, protecting, and monitoring electrical energy in various applications.

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.
