XL-21 Series Power Control-gear
Ⅰ.Overview
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 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 has flexible distribution scheme, convenient combination, good practical performance, new structure and etc. it is an ideal alternative to the old XL-21 power cabinet.
The switchgear meet the requirements of standard IEC60439 etc.
Ⅱ.Environmental conditions
1.Ambient air temperature: -5℃~+40℃ and the average temperature should not exceed +35℃ in 24h
2.Indoor altitude above sea level: Maximum installation altitude: 2000m
3.Relative humidity should not exceed 50% at max temperature +40℃. Higher relative humidity is allowed at lower temperature. (Ex. 90% at +20℃). But in view of the temperature change, it is possible that moderate dews will produce casually.
4.Installation gradient not exceed 5°
5.The equipment shall be installed in a place where there is no violent vibration and impact, and the place where the electrical components are not corroded.
6.Any specific requirement, consult with manufacture.
