XL-21 Low Voltage Electrical Power Supply and Distribution Switchboard
The new type XL-21 power cabinet is widely used in power plants and industrial and mining enterprises as three phase AC 500V three-phase three wire, three-phase four wire, three-phase five wire power distribution system for power or illumination, indoor wall installation, front panel operation, front panel inspection; Cabinet is fully enclosed structure, by C a section or 8MF profile assembly. Cabinet inside adopts the new type rotary load isolating switch with load operation , front door installed ammeter ,voltmeter and the signal lamp, button, selector switch and other components. The main distribution box adopts self-design of new components, compact structure, beautiful appearance, easy maintenance, a variety of wiring options for users to choose, it is an ideal alternative to the old XL-21 power cabinet.
The switchgear meet the requirements of standard IEC60439 etc.
Ambient temperature: -5 ℃ ~ + 40 ℃, and the average temperature within 24h not exceed + 35 ℃.
Altitude: not exceed 2000m.
The ambient air temperature of + 40 ℃ not more than 50%; at lower temperaturescan have a higher relative humidity on (eg: + 20 ℃ at 90%), taking into account the change in temperature allows the generation of a moderate condensation.
Equipment installation and the vertical gradient should not exceed 5 °
Equipment should be installed in the absence of severe vibration, shock-free and corrosion-freeplace.
