Product Description

A 35 36 kv medium voltage vacuum circuit breaker is designed for reliable control and protection of electrical equipment in power distribution networks. It is widely used in substations, industrial facilities, and power plants where stable performance and high breaking capacity are required.

The 35 36 kv medium voltage vacuum circuit breaker uses a vacuum interrupter as the arc extinguishing medium. When the contacts separate, the arc is quickly quenched in a vacuum environment, ensuring minimal wear on the interrupter and long mechanical life. This technology allows the 35 36 kv medium voltage vacuum circuit breaker to handle frequent operations and short circuit interruptions with excellent efficiency.

The compact design typically integrates the interrupter, operating mechanism, and insulation components into a sealed housing, which protects the internal parts from dust, humidity, and pollution. It makes the 35 36 kv medium voltage vacuum circuit breaker suitable for a wide range of environmental conditions.

Product FAQ:

Q: What is a 35-36 kV medium voltage vacuum circuit breaker for?

A: It is used in power distribution systems with 35 or 36 kV voltage levels. Examples include power substations, industrial plants and large commercial facilities. It provides short circuit protection for transformers, cables and other equipment.

Q: How do 35-36 kV medium voltage vacuum circuit breakers work?

A: When a fault occurs, the circuit breaker breaker contacts inside its sealed vacuum interrupter. Since the vacuum environment does not support a continuous discharge, the resulting arc is quickly extinguished. This ensures that the fault current is cut off quickly and contact wear is minimized.
