GCS low - voltage out of the cabinet
GCS-type low-voltage withdrawable switchgear is two joint design group based on industry authorities, the majority of power users and design requirements of the design and development units, in line with national conditions, with high technical performance indicators, to adapt to the development needs of the electricity market and with the present There is the introduction of competitive products out of low-voltage switchgear. The Ministry of Industry and the Ministry of Machine-Building Industry jointly issued the Circular on Issues Related to the Popularization and Application of GCS Low-voltage Draw-out Switchgear by An Sheng  No. 01 and Machine Weight  At present, GCS-type low-voltage switchgear has been widely used by power users.
Use of environmental conditions
A) Ambient air temperature not higher than 40 ℃, not lower than -10 ℃. 24 hours, the average temperature shall not exceed 35 ℃ over,
According to the actual situation derating operation.
B) indoor use, the use of the location of the elevation of not more than 2000m.
C) Ambient air relative humidity not exceeding 50% at a maximum temperature of 40 ° C and a larger phase at lower temperatures
For humidity, such as 20 ° C for 90%, should be taken into account as a result of temperature changes may occur by accident the impact of condensation. D) switch cabinet installed with the vertical gradient of not more than 5%, and the whole group of columns relatively flat (in line with GBJ232-82 standard
E) switchgear should be installed in the absence of severe vibration and shock and not enough to make electrical components should not be subject to corrosion of the place
F) The user has special requirements, can be resolved in consultation with the manufacturer.

1, the entire cabinet with assembled modular structure, modular hole installation, parts and general versatility, applicability, and a high degree of standardization
2, the upper part of the cabinet for the bus room, the front of the electrical room, the rear of the cable room into and out of room between the steel plate or insulation board for isolation to ensure safety.
3, MCC cabinet drawer cabinet doors and circuit breakers or disconnector operating handle with mechanical interlocking, only the handle in the breaking position when the door can open.
4, power switch, contact switch and MCC cabinet drawer has three positions: connected position, test position, disconnected position.
5, the top of the switchgear according to power needs can be installed bus bridge.
6, and has a high breaking capacity, dynamic thermal stability, advanced structure and reasonable, flexible electrical program, series, versatility, all kinds of program units any combination of a cabinet. The number of the circuit to accommodate more, saving floor space, high degree of protection, safe, reliable, easy maintenance and so on.
