China SF6 Gas HV CB Manufacturer, Supplier, Factory

This product is designed for 50Hz AC power distribution networks with a rated operational voltage of 380V and a rated current up to 630A. It provides reliable indirect contact protection for personnel and effectively prevents fire hazards caused by ground fault currents resulting from equipment insulation failures. The device incorporates multiple protection mechanisms to deliver precise overload and short-circuit protection for power distribution lines and supply equipment, while featuring circuit status monitoring capabilities. Under normal operating conditions, it can serve as an infrequent switching device for distribution circuits and provide occasional motor starting control functionality. The integrated design combines electrical safety protection with equipment management requirements, significantly enhancing the operational reliability of power distribution systems and fire prevention capabilities.

The KYN28-12(Z) 3.6KV 1600A MV medium voltage electrica lswitchgear is designed for 12kV rated voltage and 50Hz rated frequency in three-phase AC power systems. It is utilized for receiving and dispersing electric power, as well as managing, safeguarding, and overseeing circuits.

In recent years, the field of engineering construction has faced increasing complexity due to advancements in technology and the growth of society and the economy. There is a rising demand for compact switch equipment that is smart and requires minimal maintenance. Both local and global manufacturers of switches are currently focusing on the development of 12KV 2500A Sf6 Sulfur Hexafluoride Infiilled Electrical Switchgear, also referred to as gas-insulated switchgear (C-GIS). These C-GIS systems encase high-voltage components like busbars, circuit breakers, isolating switches, and power cables in a housing with reduced gas pressure.

The SC(B) series epoxy resin dry-type transformer has been carefully designed,Due to the most important thing is safety,and the epoxy resin dry-type transformenr is flame-retardant, fire-proof, and explosion-proof to ensure the highest level of safety. The encapsulated winding allows for direct installation in the load center, providing a maintenance-free and pollution-free solution. The scientific and rational design, combined with the casting process, results in a product with lower partial discharge, reduced noise, and superior heat dissipation capacity. When equipped with forced air cooling, it can operate for extended periods under a 125% rated load.
