Steel-Clad Removable-Type Metal-Enclosed High Voltage Switchgear
Product Overview :
KYN series metal-clad removable enclosed switch cabinet (called switch cabinet for short). It is applicable for power receiving and distribution in the 3.6-12Kv three-phase AC 50Hz single bus bar and single bus bar sectioning system. It has the functions of controlling, protecting and monitoring the circuit.
Working Conditions:
a. The Ambient temperature upper limit and lower limit are respectively +40°C and -40°C; (allowing storage and transportation at -30°C);
b. Altitude is not more than 1000m;
c. Relative humidity: daily average value should not be more than 95%, while monthly average value should not be more than 90% (+25°C);
d. Seismic intensity should be not more than 8°;
e. Places without fire, explosion risk, serious pollution, chemical corrosion and violent vibration.
