An overview,
(hereinafter referred to as GCS low-voltage withdrawable switchgear device) is two joint design according to the department in charge of industry, the majority of power users and design units developed in accordance with the requirements of design conditions, with high technical performance indicators, to meet the need of electric power market development and can compete with the introduction of existing product low voltage draw-out switch cabinet. The device has been widely use electricity users.
Device is suitable for the power plant, petroleum, chemical, metallurgical, textile, power distribution system of high-rise building and other industries. In large power plants, petrochemical system, such as high degree of automation, and computer interface, a three-phase ac frequency 50 Hz (60), rated voltage at 380, (660), rated current is 5000 a and below the hair, power supply system of power distribution, centralized control of the motor, reactive power compensation for low-voltage distribution equipment.

Second, the applicable conditions
◆ Ambient air temperature is not higher than 40 ° C +, not less than 5 ° C, and its average temperature is not higher than within 24 h + 35 ° C. Beyond, should be according to the actual situation let run.
◆ Indoor use, use the location of altitude does not exceed 2000 m.
◆ Ambient air relative humidity when the highest temperature is + 40 ° C by more than 50%, at low temperature are allowed a larger relative humidity: such as + 20 to 90%. Should be considered due to the change of temperature condensation of influence may be accidental.
◆ Device installed with a vertical gradient of no more than 5%, and the whole tank column relatively flat (GBJ232-82 standard)
◆ Device should be installed in no violent vibration and impact, and enough to reduce electrical components are not due to corrosion.
◆ Users have special requirements, you can negotiate with factory to solve.
