Draw-out type Switchgear Low Voltage Switchgear 400V Electrical movable Switchgear Suppliers
Product description
MNS Drawout Low-Voltage Switchgear is assembled with modularized components as combination unit (hereinafter called the device). It is applied to AC 50-60Hz @ rated operating voltage of 660V or below for power receiving and distribution of low voltage distribution system and for power switching, distribution and control of power distribution and motor control center as well as capacitance compensation. The switchgear cabinet complies with GB7251.12-2013.
Structural features:
The product design has fully considered the requirements of the majority of power users and design departments, which can meet the needs of the developing power industry such as the centralized control of capacity increase power, convenient installation and maintenance, and shortened accident treatment time, etc., which is safe, economical, reasonable and reliable.The product has the characteristics of strong connection ability, high breaking ability, good dynamic stability, flexible electrical scheme, convenient combination, strong series and practicability, novel structure and so on.At the same time, it can be combined with drawers and cabinets for mixed use.
Switch cabinet cabinet structure is composed of profiles (module E=25mm) assembly.As a result of using lock since tapping screw and 8.8 class high strength bolt for connection, thus high precision cabinet, good patience.
Conditions of use
1. For indoor use, the elevation of the service point shall not exceed 2000m.
2, the ambient air temperature is not higher than +40 degrees, not lower than negative 5 degrees.The average temperature should not be higher than +35 degrees within 24 hours.When exceeding, the capacity should be reduced according to the actual situation.
3. The relative high temperature of the surrounding air is +40 ° c and does not exceed 50%, and a large relative temperature is allowed at a lower temperature;If +20 degrees is 90%, consideration should be given to the effect of occasional condensation caused by temperature changes.
4. When the device is installed, the tilt with the vertical plane shall not exceed 5°, and the whole set of cabinets shall be relatively flat in line with the standard of gbj232-2.
5. The device shall be installed in a place where there is no severe vibration and impact and no corrosion of electrical components is sufficient to use
