Product Introduction

SUMMARY

 

GGD model AC LV Withdrawable applies to power plant, substation industrial enterprise, as motive force in AC 50/60Hz, rat ed working voltage 380/415V, rated current 3150A and below distribution system. For transferring power energy, distributing and controlling of lightning and distribution. High breaking capacity, rated short time current will reach 50kA. Flexible circuit scheme, convenient combination, novel structure.

 

This product conforms to IEC60439 LV Switchgear and controlgear, GB7251 LV Switchgear and controlgear etc.

 

 

OPERATING CONDITIONS

 

1. Ambient temperature: -5 ~+40 , daily average temperature +35;

2. Altitude: 2000m, indoor type;

3. Ambient relative humidity at highest temperature +40 not exceed 50%;

4. Allowed max relative humidity at low temperature, example for +20 is 90%, it will occur moderate moist due to temperature change;

5. Vertical installation, gradient: 5%;

6. Occasions without flammable and explosive matter, without corrosive chemical and frequent severe vibration.

 

 

MODEL

 

 

 

Product feature

 

1. GGD AC LV distribution panel adopts commonly type, the frame are welded or assembled by 8MF cold bend steel, the components and special fitting of frame are supplied by our company. To keep perfect precision and quality.

 

2. Commonly panel components are designed reference to module principle, 20 modular, high commonly factor, shorten production cycle and improve production efficiency.

 

3. We have taken account of heat radiation during operating when got ready to design. There are many heat radiation slotted eye from top to bottom on the body. Heat quantity will displace to direction of upper slotted eye, then the cold wind will be compensated from bottom slotted eye, when the components is heating and increase heat quantity, then form to a natural air channel.

 

4. GGD panel adopts modern industrial style design, adopts golden section method to design panel outline and section dimension of every parts.

 

5. The panel door are connected by transfer axle type moving link chain and frame, convenient to install and disassemble.

 

6.There is a rubber plastic bar in the place of edge and a compress travel between door and frame in closing.
