GCK Indoor Low Voltage Withdrawable Swithgear
Production description :
GCK type switchgear is suitable for three-phase AC 50 /60HZ, max
voltage 660V, rated current to 3150A system and three-phase
four-wire and three-phase five-wire, it is widely used in power
plants, substations, industrial and mining enterprises, hotels,
airports, docks and the building of broadcasting and communication
center, transmission & distribution and the electric energy
conversion, power distribution and power consumption in PC and
motor control center MCC.
Compared with the GCS cabinet, which has a maximum of 11 module
small drawers and a minimum unit of 1/2, and the MNS cabinet, which
has a maximum of 9 module small drawers and a minimum unit of 1/4,
the GCK can achieve a maximum of 9 modules and a minimum unit of
1.However, no matter GCS,MNS or GCK, there are three station
states: separation, test, and connection
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"
