GCK low voltage draw-out switchgear is a new developed product of our company by absorbing theadvanced technology of the same type of products abroad and improving them. This kind of switchgear, 3-phases 4-wire or 3-phases 5-wire system, 50 (60) Hz(AC), rated voltage 660V, rated current up to 4000A, is widely used in power transmission and distribution net for power distribution, lighting, motor protection and power supply in power plants, substations, works, mining, buildings, hotels, airports, seaports, etc.
Products feature :
a. Compact, space saving design: more functional units in less space.
b. High generalization in structure design and flexibility in make up. The type FA steel with 20mm modular interval can meet all needs of varied kinds of structure, protection degree and environmental condition.
c. Standard module design: They can make up a variety of standard units for protection, operating, switching, controlling, regulating, measuring and indication. The users may choose the relevant standard units for making up different structure frames and drawers units according to requirements.
d. All frame structure and its parts are zinc galvanized, so the reliability and safety protection capacity of the product has been strengthened. The front and rear doors and side plates are sprayed with static electricity plastic powder treated with high temperature technology to assure the coat is firm and color is beautiful.
e. High technical characteristics and main technical data reach a high advanced level.
f. Easy installation and disassembly without any special tools.
