OEM High Quality Low Voltage Power Distribution Supplier – GCK Low Voltage Withdrawable Switchgear – Changan Group

Product Summary

GCK low Voltage withdrawable switchgear consists of two parts, power distribution center (PC Panel) and motor control center(MCC Panel). It is universally applied in power plant, city substations, industry and mine corporations,etc., with rated voltage 400V,max operating current 4000A and rated frequency 50/60Hz. It can be applied as power conversion distribution control of the powerdistribution equipment like power distribution, electromotor control, lighting, etc.

This switchgear is accordance with international standard IEC439 and national standard GB725 1(low Voltage switchgear andcontrolgear assemblies). The main characteristics are high breaking capacity, good performance of dynamic & thermal stability,advanced and reasonable configuration, realistic electric scheme, and strong seriation and generality. All kinds of scheme units arecombined arbitrarily. A cabinet has more loops to be accommodated, which has many advantages like saving area, beautiful .appearance, high degrees of Protection, safety and reliability, and convenient maintenance, etc.

Environmental Conditions

1.Installation Site: Indoor

2.Altitude: No more than 2000m.

3.Earthquake Intensity: No more than 8 degrees.

4.Ambient Temperature: No more than +40℃ and no less than – 15℃.Average temperature is no more than +35℃ within 24 hours.

5.Relative Humidity: the average daily value is no more than 95%, the average monthly value is no more than 90%.

Product Features

1.The basic frame of this series of products is a combination assembly structure, All the structural components of the rack can beconnected to each other through screws to form a basic frame, Then, a complete switchgear can be assembled according to theneeds of the door, baffle, partition board, drawer, mounting bracket, busbar and electrical components.

2.The frame adopts special-shaped steel and is positioned by three dimensional plates: bolt connection without welding structure, soas to avoid welding deformation and stress, and improve installation accuracy. The installation holes of frames and componentschange according to modulus E=25mm.

3.The internal structure is galvanized, and the surface of the panel, the side plate and the panel are treated by acid washing andphosphating, and the electrostatic epoxy powder is used.

4.In the power center (PC) incoming cabinet, the top is the horizontal busbar area, and the lower part of the horizontal busbar is thecircuit breaker room.
