Load Breaking Switch

Sangao Load Breaking Switch is a powerful, intelligent and advanced switch for modern power distribution. Whether in industrial, utility, or renewable energy applications, it ensures safe switching with minimal maintenance and maximum reliability, as precision is also important when safety is paramount.

Working principle

When the load breaking switch is opened, the contacts are quickly pulled open through mechanical or electromagnetic operating mechanisms, and the arc is extinguished using methods such as air blowing, arc extinguishing grids, and insulating media (SF6, vacuum, or air) to ensure safe breaking of the load current.

Where can this transformation play a key role? The answer is simple - reliability and security cannot be compromised anywhere.

✔  Urban and rural power grids

✔  Industrial facilities (steel, petrochemicals, cement)

✔  Renewable energy sources (wind and solar power plants)

✔  Data centers, commercial buildings

✔  Transportation system (railway, subway, airport substation)

Assuming your project requires stable switching under frequent operations. In this case, this load circuit breaker provides the performance, safety, and lifespan you need.
