GCK (L) 1 low-voltage withdrawable switchgear
GCK (L) 1 Low voltage withdrawable switchgear is used for AC 50Hz, rated voltage 380V and below three-phase four wire or three-phase five wire systems as load center or control center distribution or control devices. The device is used for power distribution and control in power plants, substations, industrial and mining enterprises, large buildings and other places. The usage conditions are: environmental humidity not higher than+40 ℃, not lower than -5 ℃, average temperature not higher than+35 ℃ within 24 hours, altitude not exceeding 2000m, relative humidity not exceeding 85%, no significant vibration and bumps, and installation inclination not exceeding 5 ° C.
Structural features of GCK (L) 1 low-voltage withdrawable switchgear: The basic cabinet body of the device is made of high-quality cold-rolled steel plate that has been galvanized or imported aluminum coated zinc plate that has been stamped and formed. It is assembled using standardized C-shaped profiles with an E=25mm template. The structural components are highly versatile, and the overall cabinet is divided into a top horizontal busbar room and a control busbar room. The right side of the rear cabinet is sealed with flame-retardant transparent polycarbonate and separated by steel plates to ensure the safety of the GCK (L) 1 low-voltage withdrawable switchgear. Each functional unit has a door and is mechanically interlocked with the main switch to prevent the main switch from being pulled out of the operating position with load or inserted when the main switch is in the closed state.

The insertion or extraction of functional units is operated by the lever of the GCK (L) 1 low-voltage withdrawable switchgear. The height of the functional unit is ≥ 16E, and there are levers above and below for easy and flexible operation. The functional unit has three obvious positions, namely the connection position, the experimental position, and the separation position. The indicator instruments, buttons, indicator lights, and other components are mounted on a movable control panel, which is installed on the front of each functional unit and can be inserted or removed together with the unit, making maintenance extremely convenient. The GCK (L) 1 low-voltage withdrawable switchgear cabinet frame is a combination assembly structure. The entire structure of the cabinet frame has been treated with zinc and connected to each other through self tapping screws or 8.8 grade hex screws to form a basic cabinet frame. Then, according to the requirements of the scheme, corresponding doors, sealing plates, partitions, installation brackets, busbars, functional units and other components are added to assemble into a complete device. The internal component dimensions and compartment dimensions of the device are digitized using templates (module unit E=25mm). http://www.shhjzdh.com.cn/news/company/113.html
