1.Universal Cabinet Design:The GGD cabinet uses a modular universal cabinetdesign with an 8MF cold-formed steel frame.This ensures precision and quality,shortens production cycles,and improves efficiency.The surface is coated with HV electrostatic spray (2.60μ)and the color can be customized.


2.Efective Heat Dissipation:The design incorporates heat disipationholes at both ends.Heat rises and exits through upper slots, while cold air enters through lower slots,creating natural ventilation from bottom totop.


3.Aesthetic Design:Using the golden ratio,the cabinet has a beautiful and modern appearance.


4.Convenient Door Design:The cabinet door is connected with a rotary movable hinge for easy installation and removal.The door edges have foam rubber strips to prevent collision and improve protection.


5.Grounding System:Instrument doors are grounded with soft copper wire to the grounding busbar,forminga completeprot- ection system.


6.Durable Surface Treatment:HV electrostatic spray powder technology ensures strong adhesion and a matte finish to avoid glare,creating a comfortable visual environment.


7.Removable Top Cover:The top cover can be removed for easy assembly and adjustment of the main busbar.Lfting rings at the corners facilitate transport.


8.Auxiliary Circuit Design:The design includes powersupply/consumption schemes and power plant schemes.


9.Main Busbar Options:Uses single aluminum busbars for currents ≤1600A and double copper busbars for currents >1600A. Users can opt for copper busbars with the same capacity.Busbar surfaces are tin-coated.


10.Electrical Component Selection:The cabinets use advanced,mass-producible domestic &international electrical components These include various types of circuit breakers &knife switches designed for GGD cabinets,ensuring flexibility &easeof instlltion.


11.BusbarSupport:FeaturesdedicatedZMJ type combined busbar clamps &insulation support components,made from high- strength,fame-retardant PPO alloy.This design improves dynamic stability &insulation performance.


12.Protection Level:The cabinet offers protection levels of IP30/P40,with options for IP20 to IP40 based on usage requirements.

1. The ambient air temperature shall not exceed 40 ºC. And the average value measured within 24h shall not exceed 35 ˚ C. Minimum ambient air temperature - 5˚C.
2. The altitude of the installation site shall not exceed 2000 meters.
3. The surrounding air is not appreciably polluted by dust, smoke, corrosive and/or flammable gases, vapors, or salt mist.
4. Atmospheric conditions: the air is clean. When the maximum temperature is + 40 ºC, the relative humidity shall not exceed 50%. The higher relative humidity is allowed at lower temperatures. For example, the relative humidity is 90% at + 20 ºC. However, it should be considered that due to the change in temperature, moderate condensation may occur occasionally.
5. When the equipment is installed, the inclination from the vertical plane should not exceed 5˚C.
6. The equipment should be installed in a place free from severe pulling and impact.
7. Note: Users can negotiate with our company for special requirements.
