Using of the enviroment:
Ambient temperature:-40ºC~+40ºC, the daily average temperature:25ºC;
Altitude:≤ 3000m(in excess of the value of technical discussions with the divisionI);
Wind speed:35m/s;
Earthquake intensity: not more than 8 degrees;
Degree of ambient air contamination level not greater than:III level;
Daily average ambient air relative humidity≤95%, on average≤90%;
Saturated vapor pressure of daily mean values≤ 2.2*10^(-3)MPa, on average≤1.8*10^(-3)MPa;
More about the use of environment conditions, please consult with the manufacturer.
Main technical specifications:
Note: For short circuit breaking current & rated current is optional by clients.
ATTENTION:
1.The payment term: We accept TT,30% deposit and 70% balance against copy of BL.
2.The delivery time: Usually it will take about 15-20 days.
3.The standard of package: Usually use strong plywood case for protection.
4.The material of transformer: We have two types, one is with copper and another one is with aluminum. It depends on your requirement. In fact, those two have difference if normal work well. Only except the long life. Copper is better and also higher price.
