Primary/Secondary Equipment Prefabricated Cabinets: 

Primary equipment cabins are indispensable key components of power systems. Their core functions lie in isolating, connecting, disconnecting, switching, and protecting circuits. They integrate electrical components such as circuit breakers, disconnecting switches, load switches, instrument transformers, surge arresters, grounding switches, control equipment, and measuring instruments to jointly monitor, regulate, and ensure the safe operation of the power system. Secondary equipment cabins integrate secondary equipment, cabin structure, HVAC, lighting, fire protection, security, and imaging equipment into one unit. Adhering to the principles of "safety, applicability, versatility, and economy," they utilize containerized secondary modular equipment, achieving "standardized design, factory processing, and prefabricated construction," effectively shortening the construction cycle, improving construction efficiency and quality, and achieving energy conservation, land conservation, and environmental protection.
