【Summary】
GGD low-voltage switch board is suitable for such electric
users as transformer substation , power plant , industrial
enterprise ,etc.. Exchange 50Hz, amount working voltage
660V and following, specified job electric current heavy
distribution in 3150A system light as power and whom electric
energy , distribution of equipment change , assign use
most.
【Normal service condition】
1、Ambient air temperature is not higher than +40 degrees
Centigrade , it is not low- 5 degrees Centigrade, and
its average temperature is not higher than +35 degrees
Centigrade in 24 hours.
2、The air cleans, the relative humidity does not exceed
50% when the maximum temperature is +40 degrees Centigrade;
Is it have higher humidity to allow at low temperature,
for example +20 degrees Centigrade 90%; Allow because
temperature may produce and congeal to reveal while
changing.
3、The height above sea level does not exceed 2000m .

【Structure
characteristic】
1、The
cupboard shelf of GGD low-voltage switch board adopts
8MF cold curved section steel part to weld and assemble
. The spare part of the switch board is designed according
to the principle of the module , external dimension and
turning on the size of hole to press the basic modulus
E =20mm change.
2、The cupboard door is connected with cupboard body with
the pivot type activity hinge, install , dismantle it
conveniently. Hem place of door inlay have one mountain
rubber piece , can prevent door and direct collision ,
cupboard of body from, have improved the grade of shelter
of the door too.
3、Switch
board at the body, lay both ends have trough holes of
heat dissipation , after the electric apparatus component
generates heat in the cupboard, temperature rises, the
hot air is discharged through the top trough hole, and
the cold air is being supplemented by the underpart trough
hole constantly, make sealed cupboard body from bottom
to top , form one natural ventilation dish , achieve the
goal of dispelling the heat.
4、The grade of shelter of the cupboard body is IP30.
