C low-voltage draw-out switch cabinet is widely used in power distribution centers C and motor control centers of power plants, substations, factories and mines, and high-rise buildings. As AC, the rated working voltage is and below, a low-voltage complete power distribution device used for centralized control of power distribution and motors and reactive power compensation in power generation and power supply systems with rated currents of and below.
C low-voltage drawer cabinet
Structural features:
The basic cabinet frame of this series of products is a modular assembly structure. All structural parts of the cabinet frame are connected to each other through screws to form a basic frame. Doors, baffles, partitions, drawers, mounting brackets, busbars and electrical components need to be added to assemble a complete switch cabinet. This cabinet has the following features:
The frame is made of shaped steel and is positioned using three-dimensional angle plates. , Bolted connection without welding structure avoids welding deformation and stress and improves installation accuracy.
The mounting holes of the frame and components vary according to the module =.
The internal structural parts are galvanized, and the exterior is pickled and phosphated before being sprayed with electrostatic epoxy powder.
C Low-voltage drawer cabinet usage environment:
The ambient air temperature shall not be higher than +℃ and not lower than +℃. The average temperature inside shall not be higher than +℃. When it exceeds, the capacity must be reduced according to the actual situation.
. Indoor use: the altitude of the place of use shall not exceed
. When the relative temperature of the surrounding air is +℃, it shall not exceed %. At lower temperatures, a larger relative temperature is allowed, such as when +℃ %, it should be considered that the influence of condensation may occur occasionally due to temperature changes
The slope of the device when installing with the vertical surface does not exceed ℃, and the entire group of cabinets is relatively flat (in line with B standards)
. The device should be installed in a place without severe vibration and impact, and where the electrical components are not subject to undue corrosion
If the user has special requirements, they can negotiate with the manufacturer
