China Manufacturers Price Of 660v/220v Draw-Out Type Switch Cabinet
Low Voltage Switchgear
Product description
GGD AC low voltage power distributing cabinet is applicable to
power distribution system of AC 50HZ, and with a rated operational
voltage of 380V,rated operation current to 3150A in power users
like generators,transformer substation,and mining enterprises,and
it is used in power transformation,distribution and control of
driving motor,illumination and power distribution equipments.
Conditions for use
Ambient air temperature shall be neither above+40°C nor below-50°C.
Indoor installation and use,the altitude of the use venue shall not
exceed 2000M
Environment relative humidity shall not exceed 50% at the maximum
temperature of 40°C,high relative humidity is allowed when the
temperature is comparatively low.(for example,it can be90% at
+20°C).Also,the impact brought about by occasional condensation due
to temperature change shall be taken into consideration.
The gradient to vertical plane shall not be more than 5 degrees
when equipments installation.
Equipments shall be installed at places free from excessive
vibration and impaction,and where no erosion shall be caused to the
electric appliance components.
IF users have any special requirement,please negotiate with the
manufacturer for settlement..
Structural features
1. The shell is locally welded and assembled with 8MF cold-formed
steel.Mounting holes arranged by E=20mm and E=100mm modules are
arranged on the frame to improve the universality of product
assembly.The panels and baffles are made of imported cold rolled
sheet and adopt pickling, phosphating, electrostatic spraying,
anticorrosive process.Cabinet internal treatment using hot dip
galvanizing process.In order to strengthen ventilation and heat
dissipation, the bottom and upper part of the cabinet have
ventilation and heat dissipation holes, and steel wire mesh sealing
cover, to prevent small animals to enter.For the convenience of
lifting, the cabinet top four corners are equipped with
rings.Considering the use of cable outlet, in the bottom of the
cabinet set knock hole, and prepare to meet the construction
drawing size requirements of the leather line sleeve.
2. When designing the GGD cabinet, the heat dissipation problem in
the operation of the cabinet is fully considered.There are
different Numbers of heat sink holes at both ends of the cabinet,
when the electrical components in the cabinet heating, heat rise,
through the upper end of the tank hole discharge, and the cold wind
constantly by the bottom end of the tank hole supplement into the
cabinet, make the sealed cabinet body from the bottom up to form a
natural ventilation channel, to achieve the purpose of heat.
3, GGD ark according to the requirements of modern industrial
product modelling design, the method that USES golden section ratio
to design cabinet body appearance and the segmentation size of each
part, beautiful and easy, face is new.Cabinet door USES turn axle
activity hinge and frame to be linked together, installation,
disassemble is convenient, the folding place of the door is
embedded a hill model rubber model strip, the inlaid strip between
door and frame when close the door has certain compression stroke,
can prevent the door and cabinet body to collide directly, also
raised the protection class of the door.The instrument door
equipped with electrical components is connected to the frame with
multiple strands of soft copper.Knurled screws are used to connect
the installation parts and the frame in the cabinet. The whole
cabinet constitutes a complete grounding protection circuit.
