Main Feature
1. The body of GGD AC LV fixed type switchgear adopts universal cabinet type. Framework is assembled with 8MF cold bending bar steel through part welding. Framework components and special mating elements are matched by bar steel pointed manufactory for ensuring the precision and quality of cabinet. Components of universal cabinet is designed according to module principle,and with20 modulus mounting hole and high universal coefficient.
2. Completely in view of the heat rejection during cabinet running. Heat rejection slots of different quantities are installed in upper and underside both ends of cabinet.
3. According to the requirements on mold design for modern industry products, adopting the method of golden mean ratio to design cabinet outline and parting dimensions of each part, to make the whole cabinet beautiful and decent.
4. Cabinet gate is connected with framework with rotation axis type movable hinge. With convenient installation and disassembly. One mount type rubber strip is set in edge fold of gate. Filler rod between gate and framework has certain compression stroke when closing the gate. It can prevent gate from impacting cabinet directly and also advance the protection grade for gate.
5. Connect the meter gate set with electrical components with framework by multistrand soft copper wire.Connect the mounting pieces inside the cabinet with framework by knurled screws.The whole cabinet constructs complete earthing protective circuit.
6. Top cover of cabinet can be disassembled if necessary for convenience to the assembly and adjustment for main bus bar at site. Four squares of cabinet are set with slinger for hoisting and shipping.
7. Protection grade of cabinet: IP30. User can choose within IP20~IP40 according to environmental requirements.

1. Commercial Complexes & High-Rise Residential
Modern commercial complexes and high-rise residential buildings require reliable, compact, and fire-safe power distribution equipment.
2. Industrial Parks & Heavy Manufacturing
Industrial parks and heavy manufacturing facilities, including steel mills, cement plants, chemical factories, and automotive assembly lines, consume large volumes of medium-voltage power and require robust, outdoor-rated distribution equipment.
3. PV & Energy Storage Grid Connection
Solar photovoltaic farms and battery energy storage systems (BESS) require dedicated step-up transformer solutions to interface with the medium-voltage grid.
4. Infrastructure — Rail Transit, Healthcare & Data Centers
Critical infrastructure applications, including metro and railway systems, hospitals, and data centers, demand the highest levels of power reliability and redundancy.
5. Municipal & Environmental — Water Treatment & Pumping Stations
Municipal water supply, wastewater treatment plants, and flood control pumping stations present challenging operating conditions for electrical distribution equipment.
Use Environmental Conditions
1. Ambient air temperature: -5℃ ~+40℃ and the average temperature should not exceed +35℃ in 24h.
2. Relative humidity should not exceed 50% at max temperature. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20℃ . But in view of the temperature change, it is possible that moderate dews will produce casually.
3. Altitude above sea level should not exceed 2000M.
4. Installation gradient not exceed 5° .
5. Indoor without dust, corrosive gas and rain water attack.
