Pole Mounted Outdoor SF6 Load Break Switch 15kV

Features

• The Load Break Switch tank is fabricated with high-quality 3 mm stainless steel.
• The Load Break Switch adopts minimized welding lines to reduce corrosion risk and fully ensure operational safety for field personnel.
• Even under internal arc faults at maximum fault capacity, the Load Break Switch tank can withstand internal faults without venting hot gas, greatly improving system safety.
• The Load Break Switch is equipped with an independent spring operating mechanism, adopting ROCKWILL® patented spiral spring. It maintains stable opening and closing speed, ensuring excellent load breaking and fault making capability of the Load Break Switch.
• The Load Break Switch is fitted with a light-reflecting position indicator directly linked to the operating shaft, delivering clear and accurate status indication for the Load Break Switch.
• Made of high-visibility reflective material, the indicator of the Load Break Switch is clearly visible from ground level, even at night and in heavy rain conditions.

 What is a tank circuit breaker compressed air interrupter？

Working Principle：

• Working Principle: During the opening operation of the circuit breaker, the moving contact compresses the SF₆ gas within the arc quenching chamber, increasing the gas pressure and causing it to flow rapidly toward the arc region. The high-speed gas flow blows and cools the arc, effectively extinguishing it. During the closing operation, the gas returns to its original state as the moving contact moves in the opposite direction.

Features：

• Excellent Interrupting Performance: The pressurized arc quenching chamber offers excellent interrupting performance, with a short arcing time and long electrical life.

• Multiple Interruptions: It can continuously interrupt large short-circuit currents at rated voltage multiple times without frequent maintenance.

• High Mechanical Reliability: The design ensures high mechanical reliability.

• Suitable for High Voltage Systems: It is suitable for transmission and distribution systems operating at 40.5 kV and above. For example, the LW8-40.5 type SF₆ circuit breaker uses a pressurized arc quenching chamber.
