Description
High-voltage and low-voltage switchgear are devices connected to high-voltage or low-voltage cables. General power supply bureaus and substations use high-voltage cabinets, which are then stepped down to low-voltage cabinets through power transformers, and then to each distribution box through low-voltage cabinets. It is an electrical equipment assembled by some switchgear, circuit breakers, protection devices and circuit breakers.
Operating environment
a. Ambient temperature -10℃~+45℃
b. Relative humidity: daily average value should be less than 95%, monthly average value should not be greater than 90%
C. Altitude: no more than 1000m, if it exceeds 1000m, the capacity will be reduced according to the altitude.
d. The earthquake intensity should be less than 8.
e. It should be operated in a place where there is no fire, explosion, serious dirt, chemical corrosion and severe shaking.
If it is planned to operate under conditions outside the above restrictions, the customer should consult with us to determine the allowable operating conditions and technical measures.
Application
High and low voltage switch cabinets are widely used in power stations, substations, residential power distribution places, high-rise buildings, industrial parks, metallurgy, steel mills, chemicals, factories, mines, oilfield enterprises, etc.
