Description
YBW modular box-type electrical transformer substation is a self-designed power distribution equipment according to the power market needs, composed of high-voltage switchgear, power transformer and low-voltage switchgear, with the advantages of flexible design scheme, compact structure, easy installation, short commissioning period, easy removal ,artistic, practical and so on.
Application
YBW modular box-type electrical transformer substation can be used not only in the ringed network distribution system ,but also in the emanant network terminal power supply. It is widely used in urban network recondition, high buildings, residential quarters, hotel, schools, hospitals, airports, wharves, city public power distribution, industry zone, industrial and mining enterprises, tourism spots, expressways, temporary facilities and etc.
Normal operating conditions
- Ambient air temperature : -25°C ~ +40°C;
- Daily average temperature(Within 24h): ≤+35℃
- Altitude:≤1000m;
- Relative humidity: winthin 24h, daily average value ≤ 95% , daily average vapor pressure≤ 2.2KPa; monthly average value≤ 90%, monthly average vapor pressure ≤ 1.8KPa
- Installation places :without fire, explosion risk, serious pollution, frequent violent vibration, corrosive gas and conductive dust.
Special operation conditions
If the switchgear will be used in conditions that exceed the normal environmental conditions, users should consult with the manufacturer.
