1.Overview GCS(II) low voltage switchgear cubicle is suitable for system with AC50 Hz,rated working voltage up to 660v,current up to 4000A,and applicable for power generation,transmission,distribution,charge-over and consumption equipment control.It conforms of relevent standards such as IEC60439-1,GB7251.1 and JB/T9661 and are widely used in power plant,metallurgical factory,petroleum industry,chemical industry,textile industry and high-rise buldings. Designed with advcance manufacturing technique and a modularized and flexible structure,GCS(II) can replace all traditional GCS solutions in the market. 2.Dimension
3.Main characteristics 1.The frame is adopted with C profiles.The mounting holes in φ5.3mm with module E=25mm on the main framework enables its assembly fixible and convenient; 2.The]switchgear is divided into function unit compartment,busbar compartment and cable compartment with each compartment isolated and function relatively independent. 3.The horizontal busbar is placed flat at the back as to strengthen its capability against electromative power,which is a basic measure to make the main circuit have strong short circuit capability; 4.The design of cable compartment facilitates easy access of cable; 5.The drawer height is 150mm,200mm,300mm,400mm,500mm,600mm,same in width and depth.The drawers of same function units have great interchangeability.The rated current of unit loop is up to 400A; 6.The drawer panel is marked with obvious signs for positions as breaking,making,testing and drawing out.The drawer unit is provided with mechanical interlock device.Usually,drawer units are the main options,but they can be mountd together with fixed units in one cubicle for random use; 7.The degree of protection of the enclousre is IP30-IP40; 8.Material optional with cold rolled steel,galvanized steel or Aluminum-zinc coated steel.
