20kV Outdoor High Voltage Pole-mounted Circuit Breaker ZW32-24kV/630A | 24kV Distribution Network Control and Protection Equipment

Overview

ZW32-24kV/630A Outdoor High Voltage Pole-mounted Vacuum Circuit Breaker (hereinafter referred to as circuit breaker) is control and protection equipment in rated voltage 24kV, 50Hz AC three-phase high voltage distribution networks. Mainly used for breaking and making load current, overcurrent and short-circuit current in power lines. Suitable for protection and control in substation and industrial/mining enterprise distribution systems.

This circuit breaker adopts post-type dry structure, reliable insulation, long electrical life, maintenance-free, especially suitable for frequent operation occasions, and more suitable for installation and use in rural power grids with limited maintenance capabilities. It can also serve as a section switch in the power grid, and with a controller installed, distribution automation can be achieved. Complies with GB1984 "AC High-voltage Circuit Breakers", GB1985 "AC High-voltage Disconnecting Switches and Earthing Switches", DL/T402, DL/T4.3 and enterprise standard OHX.520.701.

Service Environment Conditions
