12KV SERIES INDOOR HIGH-VOLTAGE AC VACUUM CIRCUIT BREAKERS

The YFGZGS2 series indoor high-voltage AC vacuum circuit breakers have been successfully developed independently by our company. They feature excellent electrical and mechanical properties, with a reliable and stable mechanism, safe and reliable breaking performance, a long electrical life, the ability to be frequently operated, a large short-circuit current breaking capacity, being basically maintenance-free, and having obvious isolation breaks.
The outstanding insulation and mechanical properties of the products ensure that the switches can operate reliably even in severely polluted environments. They also have a complete set of dedicated mechanical and electrical interlocking functions to ensure the safety of operators and equipment.

40.5KV SERIES INDOOR (SOLID-INSULATED POLE WITH THROUGH-CORE TYPE) INDOOR AC HIGH-VOLTAGE VACUUM LOAD SWITCHES.

It is specially designed for the 35kV series used in wind power generation and solar power generation, and can be applied as an independent electrical unit in 40.5kV power systems or in box-type substations. This product has a reasonable structure and adopts the CTE3 two-stage transmission spring operating mechanism independently developed by our company and which has obtained the national invention patent. Its operation is simple and reliable.

40.5KV SERIES INDOOR HIGH-VOLTAGE AC VACUUM CIRCUIT BREAKERS WITH ISOLATION AND SOLID INSULATION.

This product is a new generation of 40.5kV combined vacuum circuit breakers that are independently designed and developed and possess a domestic leading level. It has complete functions and its mechanical properties are stable and reliable. It is applicable to relatively harsh environments such as high-altitude areas and seaside areas with dense salt fog, and can be widely used in projects like wind power generation, photovoltaic power generation, energy storage power stations and urban distribution networks. It has a complete set of mechanical and electrical interlocking devices, and when cooperating with corresponding switch cabinets, it can achieve safe power distribution functions and ensure the safety of operators and equipment.
