This product is suitable for use in 63kV-132kV power systems, providing protection and control for high-voltage transmission and distribution systems. It fully utilizes the arc-quenching effect to increase the pressure of SF6 gas in the pressure cylinder, significantly reducing the diameter of the pressure chamber and lowering the operating power required by the circuit breaker. This enables the use of a spring-operated mechanism with no oil leakage and higher reliability. Additionally, operating noise is greatly reduced, making it ideal for urban grid renovation projects.
This product is suitable for three-phase 50Hz AC power systems and is used to switch load currents, overload currents, and short-circuit currents. It is particularly suitable for applications requiring frequent operation.
This product is suitable for outdoor distribution equipment with three-phase AC 50–60 Hz. It has a rated voltage of 12 kV or 15 kV and is used for protection and control in substations and industrial and mining enterprise distribution systems, as well as in rural grids where frequent operations are required. It can also be used as a ring network power supply unit and terminal equipment for power distribution, control, and protection of electrical equipment. This circuit breaker can be paired with a controller to form a recloser, enabling remote control, remote measurement, remote signaling, and remote adjustment (“four remote” functions).
This product is suitable for power systems with rated voltages of 12kV, 24kV, and 40.5kV, rated currents of 400/630A, and frequencies of 50/60Hz. It is a high-performance, long-life switch capable of closing and interrupting load currents and carrying fault currents during transfers, compliant with standards such as IEC 60265 and GB 3804. The product features a stainless steel housing, extremely short arc duration (within half a cycle), and contacts made from arc-quenching materials, ensuring a long service life and enhanced capability to interrupt short-circuit currents. It can be operated manually or by a DC motor located in the motor compartment beneath the housing.
