1.    Purpose

GCT Series Low Voltage Drawable Switchgear, a developed product of our company by absorbing the advanced technology of the same type of products in domestic and abroad and improving them, is a newly one which technology has reached to an international leading rank in the world in the 1990s.

This kind of switchgear, with frequency of 50 Hz (AC), rated voltage 660V max, rated current up to 4000A, is widely used in power transmission, distribution and controlling net for power distribution, lighting, motor protection and power supply in power plants, substation, works, mining, building, hotel, airport, seaport, etc.

GCT switchgear complying to standard of IEC439 Low-voltage switchgear and Control-gear assemblies and the GB7251 Low-voltage and Control-gear assemblies, had advantage of excellent breaking capacity, good dynamic stability, newly structure, a reasonable and complete electrical scheme, a serial and applicable design and higher protection degree and is a kind of ideal and renew product.

2.    Service condition

2.1    Ambient temperature shall be not more than 40℃ and not less than -5℃, daily average temperature shall be not higher than 35℃.

2.2    Air condition: clean air, relative humidity under highest temperature shall don't exceed 50%. If under low temperature , allow to has higher relative humidity ( for example +20℃ is 90%). It shall consider the condensation influence because of temperature difference.

2.3    Lean of vertical shall don't exceed 5 degree. Elevation shall don't exceed 2000m.

2.4    Medium has no explosion danger and in the medium has no air and conduct dust which may rust metal or damage insulation. If you have some special requirement, please negotiate with our company.

3.    Product characteristics

3.1    Compact, space saving design.

3.2    High structure generality and flexible assembly: C type material which take 25mm as modular can meet all of the needs of varied kind of structures, protection grade and service condition.

3.3    Adoption of standard module design: respectively make up a variety of standard units for protection, operation, transferring, control, regulation, test and indication. The user can choose any relevant standard units for assembly according to requirements. Up to more than 200 of assembly parts can make up a variety of frame structure and drawer unit for different scheme.

3.4    Safe and reliable: adopt high strength flame-resisting engineering plastic component to effectively strengthen the protection safety performance.

3.5    High technical performance: main technical data reach to international advanced level on the present day.

3.6    Easy installation and disassembly without any special tools.
