High Voltage Air Circuit Breaker

Our High Voltage Air Circuit Breaker serves a specific market need. This product is designed for substation retrofit projects. Many older installations still use air circuit breakers in their original form. These stations may need spare parts or replacement units during phased upgrades. We maintain the capability to produce this technology. Our engineers have deep knowledge of compressed air arc-extinction methods. They understand the safety and reliability requirements for air breakers. This product covers 110kV and 252kV voltage levels. It uses compressed air as both the arc-quenching and insulating medium. When the breaker opens, high-pressure air from storage tanks flows out at high speed. This strong airflow cools and extinguishes the arc quickly. This opening method provides high breaking capacity and fast operation. Air breakers were the mainstream high-voltage equipment in their era. They still hold value in certain retrofit scenarios today.

Our High Voltage Air Circuit Breaker comes with complete technical documentation. We provide operation manuals and maintenance guides with each unit. Our technical team has deep experience with this product type. They can answer questions about installation and operation. The HK series is our standard air breaker product line.
