Product Description
GGD type AC low voltage fixed switchgear is our mature mainstream low-voltage complete equipment, manufactured in strict accordance with GB 7251 and IEC 60439 international standards. The cabinet adopts 8MF standardized cold-formed steel frame with integrated welded and assembled structure, featuring high rigidity and low deformation. Its busbar system boasts outstanding short-circuit resistance, with rated current ranging from 1000A to 3150A and short-time withstand current up to 50kA. The interior is divided into physically isolated busbar compartment, cable compartment and component compartment, with standard IP40 protection grade to resist dust and foreign matter intrusion. All internal components are sourced from top-tier brands, equipped with comprehensive multi-protection against overload, short circuit and electric leakage, delivering low failure rate and long service life. Multiple cable entry ways (top/bottom/rear) are available, and custom modules including double busbar, reactive power compensation and energy metering are optional.
Application Introduction
It is widely used in 380V low-voltage power distribution scenarios such as industrial plants, commercial complexes, residential communities, hospitals, schools, data centers, municipal power distribution rooms, photovoltaic and wind energy energy storage supporting projects, serving main incoming power, bus tie, power distribution, lighting control and reactive power compensation. Supported by our full high & low voltage industrial chain layout, it can be fully matched with KYN28 high voltage switchgear, GCS withdrawable switchgear, XL-21 power cabinet and JP integrated distribution box. We provide one-stop overall power distribution solutions covering high-voltage incoming, transformation, low-voltage main distribution and terminal metering. With thousands of medium & large project cases, we deliver full-chain services including scheme design, customized production, full factory inspection, on-site installation guidance and lifelong after-sales maintenance, to fully satisfy power distribution demands of industrial & commercial, new energy and municipal projects.
Complete climate control, automated feeding/egg collection, and manure drying systems. (Exported to 30+ countries)
Water treatment plants must operate reliably around the clock, often in remote locations. Unplanned downtime, high energy consumption, and inefficient manual processes are common pain points.
Mining operations demand rugged, reliable electrical equipment capable of performing in harsh conditions—extreme temperatures, dust, moisture, and vibration.
Food processing facilities require strict hygiene standards, precise temperature control, and reliable production line uptime.
Non-ferrous metal processing—including aluminum, copper, and rare earth refining—involves high-temperature operations, large electrical loads, and complex process control.
Residential and commercial communities need reliable, safe, and efficient power distribution.
