Product Description:

Product model: GCS
Product features: has two type GCS low-voltage withdrawable switchgear joint design according to the department in charge of industry, the general electric power users, and the requirement of design unit design conforms to the national conditions, with high technical performance indicators, can adapt to power market development needs and can compete with the introduction of existing product select switch equipment.
Cardiac switchgear is suitable for the power plant, petroleum, chemical, metallurgy.Textiles.Distribution system of high-rise building and other industries and the large power plants, petrochemical system, such as high degree of automation, requirements and computer connection, as the frequency of the three-phase ac 50 Hz (60), the rated working voltage of 380 v, 660 v), rated current is 4000 a and below the power distribution, centralized control of the motor, reactive power compensation using low-voltage power distribution equipment.
Product standards: cardiac GB7251 low-voltage complete switch equipment and control equipment.
Cardiac JB/T9661 low-voltage withdrawable switchgear
Has it - 1 low-voltage complete switch equipment and control equipment
Product structure: cardiac switchgear 8 mf steel is used in the main frame.The architecture using both assembly and parts of welding structure.Are installed on the main frame modulus E = 20 mm holes. 
Cardiac switch equipment strictly separate each function room, the main compartment is divided into functional unit rooms, bus room, cable room, the function of each unit are relatively independent.
Cardiac feeder tank and motor control cabinet is equipped with a dedicated cable compartment, functional unit room and indoor cable connected by connecting pieces, can not only improve the using reliability of cable, and made great user for cable installation and maintenance.Cable compartment has two width size and 40 mm to 240 mm is chosen, depending on the number of cable, cross section and the requirements of the users for installation and maintenance is convenient.
Has given the dry type transformer using regular sex, security and economy of oil-immersed transformer, device can be easily arranged and composed of a dry type transformer, can also convenient and oil-immersed transformer low-voltage busbar connection.
Is left to the drawer as the main body, the switch can also be fixed installation, hybrid combinations, arbitrary selection.
Cardiac switch equipment according to the three phase five wire system and three phase four wire system design, the design department and the user can easily choose PE + N or PEN. 
His cabinet put oneself in another's position of the degree of protection for IP40, also can be made with customers' special needs.
Bus: left to improve the bus move the rise of temperature of the thermal stability of ability and improvement of the interface, device adopt hard copper platoon TMY - T2 series, copper platoon connection post points must be tin plating, also can choose 2 tin plated copper bus bar. 
Bus filled level in tank at the back of the bus interior insulation, more than 2500 a for layout, up and down double 2500 a for single layer under the arrangement, each phase is composed of article 4 or article 2 bus, bus short-circuit strength was improved greatly. 
The vertical busbar is left for the drawer with "L" shape hard copper tin plating.L (mm) : (50 + 30 bus specification) x 5 rated current 1000 a
Has completed the entire cabinet arrangement level of neutral grounding line (PEN) or + neutral wire (PE + N) using hard copper platoon.
