Product Description
GCK Low-voltage Withdrawable Switchgear
GCK (L) series low-voltage withdrawable power distribution cabinet meets the standards of IEC 60439-1, GB7251.1-2013, GB7251.12-2013 and JB/T9661-1999. The installation and connection of the system are performed according to the standard IEC364.
This series of low-voltage withdrawable switchgear is suitable for power plants, substations, petrochemicals, metallurgical rolling steel, transportation energy, Light industrial textiles and other factories and mines, residential quarters, high-rise buildings and other places, for the exchange, distribution and control of power distribution equipment of 50-60Hz, rated working voltage AC 660V and below.
The frame structure of the GCK (L) series low-voltage withdrawable switch cabinet is flexible in assembly, and different standard components can be installed in the cabinet to meet various application requirements. The withdrawable unit adopts the aluminum alloy sliding guide rail and screw propulsion mechanism, which has obvious working positions and is light and reliable to operate.
The ambient air temperature is not higher than +40 ° C, not lower than -5 ° C, and its average temperature is not higher than +35 ° C within 24 h. Atmospheric conditions: The air is clean, the relative humidity is not more than 50% at a maximum temperature of 40 ° C, and a higher relative humidity is allowed at a lower temperature, for example, 90% at 20 ° C. However, due to temperature changes, condensation may occur by chance. Altitude does not exceed 2000M The device is suitable for transport and storage at temperatures between -25 ° C and +55 ° C, up to +70 ° C in a short time (not exceeding 24 h), at which the device should not be subjected to any Unrecoverable damage and should work properly under normal conditions. If the above conditions of use are not met, it should be resolved by the user and the manufacturer. When the device is used in oil drilling platforms and nuclear power plants, a technical agreement shall be signed separately
Note:
1.Indoor altitude above sea level: Maximum installation altitude: 2000m
2.Ambient air temperature: -5ºC~+40ºC and the average temperature should not exceed +35ºC in 24h
3.Relative humidity should not exceed 50% at max temperature +40ºC. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20ºC. But in view of the temperature change, it is possible that moderate dews will produce casually.
4.No fire, explosion danger, serious pollution, chemical corrosion and severe vibration
5.Installation gradient not exceed 5°
6.This product is suitable for the following temperature transportation storage: -25ºC ~+55ºC 24h, in a short period of time (no more than 24hours) not more than+70ºC.
7.Any specific requirement, consult with manufacture Characteristics This series of products with high breaking capacity, good dynamic stability, advanced and reasonable structure, electrical program of practical, series, strong versatility, various schemes of unit combination, a cabinet contained many circuits, save the area , beautiful appearance, high level protection, safe and reliable, convenient maintenance etc. It accords with the standards IEC439 NEMA ICS2-322 as well as the GB7251-87 "Low voltage complete switch device " national standards and ZBK36001-89 "low voltage withdraw type complete switch device" professional standards" Technical data
