1. Operating Conditions
Ambient temperature: max. to 40 centigrade, min. to -10 centigrade
Altitude: not exceeding 1000m
Relative humidity: daily average less than 95%, monthly less than 90%
Earthquake intensity: less than 8 magnitudes
Installation site: without fire risk, explosion hazard, heavy pollution, chemical corrosion and violent vibration
Note: Special condition and requirements, consult with the manufacturer
2. Characteristic
Metal-clad and partition completely, effectively prevent faults spreading
The low voltage section is completely separated from the high voltage sections
Enclosure protection degree is IP4X, protect against electric shock and ingress of solid foreign bodies
Simple but effective interlocking prevents mal-operation
Space is provided for multiple cable connections. Installation and maintenance is convenient
Withdrawble part of the same design are mutually interchangeable, an exchange of VCB is very simple.

5. Construction
The basic structure of the switchgear panel comprises the panel itself and withdrawable part.
The panel is constructed by bolting together. Enclosure and internal partition are of anticorrosive steel sheets. The panel consists of four separate compartments, that is truck compartment, busbar compartment, cable compartment, low-voltage maintenance type, double-face maintenance type. Withdrawable part can be classified by function to:
VCB truck
PT truck
Disconnect truck
Metering truck
HV fuse truck etc.
