High and low voltage switchgear is a kind of electrical equipment used for power distribution, power transmission and power conversion. It is mainly composed of isolators, disconnecting switches, operating mechanisms, mutual transformers and other various protection devices. For the installation of high and low voltage switchgear cabinet, certain installation standards should be observed.

1, the distribution cabinet should be installed in a dry, safe and easy to operate place. Its bottom should be 1.5 meters from the ground, and the lighting distribution board should be more than 1.8 meters from the ground.

2, high and low voltage switchgear distribution box panels installed on the knife gate automatic switch light, in the circuit breakers, blade Kedong part of all should not take point.

3, wire handling prohibit damage to the wire core, wire crimp should also be firm and reliable. In general, are added to the crimp terminals together with tin shabu, and then pressed on the terminal row. If connected with the crimp hole, the multi-stranded wire should be shabu-shabu after perforation with the top wire crimp, but be careful not to reduce the number of strands of wire.

4, high and low voltage switchgear terminal box should be installed firmly, well sealed, the location of the installation should also be easy to check.

5, distribution box on the electrical appliances, instrumentation should be firm and neat, evenly spaced, no loose copper terminals, open and close the flexible, complete parts.

In addition, in the installation of high and low voltage switchgear cabinet, should be checked in advance whether the road is smooth, if necessary, need to connect the installation point and transportation channel. And check the state of construction machinery, can work normally. Also pay attention to the layout of the construction site, should meet the requirements of civilized construction.
