Product details
Product Overview
LW36-40.5 type self powered outdoor high-voltage AC sulfur hexafluoride circuit breaker (equipped with SRCT36A spring mechanism) is suitable for control and protection equipment in AC 50Hz, 40.5kV power systems. This product can be operated frequently and can be used as a contact circuit breaker. Simultaneously applicable to the working conditions of switching capacitor banks and cables. In addition, this product can be equipped with an internal or external current transformer for measurement and protection purposes.
The circuit breaker complies with the requirements of GB1984 "High Voltage AC Circuit Breakers", IEC62271-100 "High Voltage AC Circuit Breakers", and 0SR.520.002 "Technical Specifications".
The circuit breaker uses SF6 gas as the insulation and arc extinguishing medium, adopts the self energy arc extinguishing principle, and is equipped with a new spring operating mechanism. It has the characteristics of strong breaking ability, low operating power, and high reliability.
