GGD Low Voltage Power Distribution Cabinet

Selection

Operating conditions

1. Ambient air temperature: -15℃ ~+40℃ Daily average temperature: ≤35℃ When the actual temperature exceed the range, it should be used by reducing the capacity accordingly. 2. Transport and store temperature: -25℃ ~+55℃ . do not exceed +70℃ in short time. 3. Altitude: ≤2000m 4. Relative humidity: ≤50%, when temperature is +40℃ When temperature is low, larger relative humidity is allowed. when it is +20℃, relative humidity can be 90%. Since the temperature change will make out condensation. 5. Installation inclination: ≤5% 6. Applicable in the places without corrosive and flammable gas. Note: Customized products are available.

Features

1. The accuracy and quality of the switchgear could be ensured as the framework parts and special parts supplied by CNC. Modular design of the Overall and mounting dimensions(mm) s concering(E=20mm), which has cut production time and enhanced efficiency. 2. The heat dispensation channel at the top and bottom of the switchgear formulate a ventilation loop to dispens the beat. 3. Easy for installation and dismantling. 4. The switchgear with perfect earthing protection system. 5. The cover of the switchgear could be removed for installation and adjustment of the main bus bar. there are also rings for lifting and delivery of switchgear 6. The protection degree is IP30,As per you requirements,switchgearswith protection degree of IP20~IP40 are available. 7. Flexible circuit plans are available.
