XL-21 low-voltage power distribution cabinet is suitable for power distribution in power plants and industrial and mining enterprises, in the AC voltage of 500 volts and below the three-phase four-wire or three-phase wireless system for power distribution. XL-21 low-voltage power distribution box is an indoor device installed against the wall and overhauled in front of the screen.
1.The ambient air temperature is not higher than +40°C and not lower than -5°C. The average temperature within 24 hours must not be higher than +35°C.
2.For indoor installation and use, the altitude of the place of use shall not exceed 2000m.
3.The relative humidity of the surrounding air does not exceed 50% at the maximum temperature of +40°C, and a large relative humidity is allowed at lower temperatures. (e.g. 90% at +20°C) is concerned about the effects of occasional condensation due to temperature changes.
4.The inclination between the equipment and the vertical plane when installed is not more than 5%.
5.The equipment should be installed in a place where there is no violent vibration and impact, and a place where the electrical components are not enough to be corroded.
6.When the user has special requirements, negotiate w2ith the manufacturer to solve the problem.
When placing an order, the User shall provide:
1. Main circuit distribution system diagram phase layout diagram. Rated working voltage, rated working current, protection device walking current and necessary technical parameters.
2. Indicate the specifications of incoming and outgoing cables.
3. The model, specification and quantity of the main electrical components in the differential cabinet.
4. If the bus extrusion or bus duct is required between the switch cabinets or the incoming cabinets, the specific required data such as span and height from the ground shall be indicated.
5. When the switch cabinet is used under special environmental conditions, it should be detailed when ordering.
6. Surface color of the switch cabinet and other specific requirements.
