Product Introduction

Overview:

This product incorporates advanced foreign technology, featuring a compact size—only 50% of the volume of conventional switchgear. The circuit breaker is highly reliable with excellent performance. The "five-proof" interlock mechanism is reliable and simple. The switchgear is a complete indoor unit for 3.6, 7.2, and 12kV three-phase AC power systems with 50Hz frequency, designed for single busbar sectioning. It is used for receiving and distributing electrical energy, as well as for controlling, protecting, and monitoring circuits. It can be used in various power plants, substations, industrial and mining enterprises, and high-rise buildings. It can also be combined with ring main units for use in switching stations.

Operating Conditions:

  • Altitude not exceeding 1000 meters;
  • Ambient temperature: -25°C to +40°C, with a 24-hour average temperature not exceeding +35°C;
  • Horizontal tilt: Not greater than 3°;
  • Seismic intensity: Not exceeding 8 degrees;
  • Suitable for locations without severe vibration, shock, or explosion hazards.
