Switchgear Product Features
1. switchgear Compact design, with a smaller space can accommodate more functional units;
2. The mechanism is versatile, flexible assembly, to E = 25mm for the modulus C-profile to meet a variety of structural types, protection class, the use of environmental requirements.
3. switchgear uses standard modular design to more than 200 kinds of components can be composed of different programs of the cabinet structure and drawer units. Respectively, can be assembled into protection, operation, conversion, control, regulation, measurement, instrumentation and other standard units, the user can choose according to the need for assembly.
4. Operation and maintenance of switchgear is safe and reliable. Cabinet divided into three areas: electrical area, cable area, bus zone.
5. Compress the site. High degree of three, can be greatly compressed storage and transport prefabricated sites.
6. switchgear is easy assembly, no special complicated tools are needed.
7. Drawer unit with a small, powerful, easy to replace and other characteristics, contact with the close, high reliability.
Conditions of Use of switchgear
1. The ambient air temperature is not higher than +40 ℃, the lower limit of -5 ℃, and 24h the average temperature is not higher than +35 ℃.
2. Air clean, relative humidity at the maximum temperature +40 ℃ not more than 50%, at lower temperatures allow a higher relative humidity, such as +20 ℃ when it is 90%.
3. Altitude not exceeding 2000m.
4. There is no fire, explosion hazard, serious pollution, chemical corrosion and severe vibration of the place, installation gradient ≤ 5%.
5. The switchgear to adapt to the following temperature transport and storage: -25 ℃ ~ +35 ℃. In a short time (not more than 24h) does not exceed +70 ℃.
6. If the use can not be met, the user and the manufacturer should be resolved through consultation.
