Product description
GCS-type low-voltage withdrawable switchgear is the two joint design group according to industry authorities, the majority of power users and design units designed and developed, in line with national conditions, with high technical performance indicators, to adapt to the development of the electricity market and with the There is the introduction of product competition low-voltage withdrawable switchgear. Ministry of Electric Industry and Ministry of Machinery Industry jointly issued the Notice on the Relevant Issues Concerning the Promotion and Application of GCS Type Low Voltage Extraction Switchgear with the use of [1997] No. 01 and No. [1997] 01. At present, GCS low voltage withdrawable switchgear has been widely used by electric power users.
Use environmental conditions
A) ambient air temperature is not higher than 40 ℃, not less than -10 ℃. the average temperature within 24 hours shall not exceed 35 ° C,
Need to run according to the actual situation.
B) Indoor use, the use of the location of the elevation of not more than 2000m.
C) Ambient air relative humidity, no more than 50% at maximum temperature of 40 ° C, allow for larger phase at lower temperatures
for humidity, such as 90% at 20 ° C, should be taken into account due to changes in temperature may cause occasional condensation. D) switchgear installation and the vertical surface of the tilt of not more than 5%, and the entire cabinet column is relatively flat (in line with GBJ232-82 standard
Quasi).
E) the switchgear shall be installed in places where there is no severe vibration and shock and is insufficient to cause electrical components to be protected from corrosion
F) When the user has special requirements, it can be negotiated with the manufacturer.

Features
1, the entire cabinet with assembled modular structure, modular hole installation, parts versatility, good applicability, 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 into the outlet room, the room between the steel plate or insulation board for isolation to ensure safety.
3, MCC cabinet drawer compartment door and circuit breaker or disconnector of the operating handle with a mechanical interlock, only the handle in the broken position when the door can be opened.
4, power switch, contact switch and MCC cabinet drawer has three positions: connected position, test position, open position.
5, the top of the switchgear according to the power needs can be installed bus bridge.
6, and has a high breaking capacity, dynamic and thermal stability, advanced structure and reasonable, flexible electrical program, series, versatility, all kinds of units of any combination, a cabinet. The number of loops to accommodate more, save the area, high degree of protection, safe and reliable, eAsy maintenance and so on.
