High Voltage Circuit Breaker

SanGao High Quality High Voltage Circuit Breaker is an outdoor distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing load current, overload current, and short-circuit current in power systems. It is suitable for distribution control in substations, industrial and mining enterprises, and urban and rural power grids, especially for frequent operation scenarios. This product complies with GB1984-2003, DL/T 402-2007, and IEC60056 technical standards, and supports remote monitoring and automation control.SanGao has gradually become a high quality supplier in China's High Voltage Circuit Breaker industry. They are widely used in urban and rural power grid renovation, transmission and distribution engineering, sewage treatment, hydropower stations, wind power plants, metallurgical industry, petrochemical industry, mining, railways, residential area construction, and power engineering projects. Normal operating environment ◆ Surrounding air temperature: -30 ℃~+60 ℃; ◆ Altitude: not exceeding 3000m; The wind speed does not exceed 34m/s; Vibration or ground motion from outside the switchgear and control equipment can be ignored; Pollution level: Level IV; Storage temperature: -40 ℃~+85 ℃. Characteristics of switch structure 1. The High Voltage Circuit Breaker features a three phase pillar structure that is maintenance free, small in size, lightweight, and has a long lifespan. 2. The circuit breaker adopts a fully enclosed structure with good sealing performance, which helps to improve moisture proof and anti condensation performance, especially suitable for use in cold or humid areas. 3. The three-phase pillars and current transformers adopt imported outdoor epoxy resin solid insulation, or indoor epoxy resin wrapped with organic silicon rubber solid insulation; It has the characteristics of high and low temperature resistance, UV resistance, and aging resistance.
