Connection symbol:Dyn11,Yyn0

insulation level:LI125AC50/LI0AC3

Product feature:

1.        Advanced and reasonable structure,small volume,light weight,convenient instllstion,maintenance-free and good economy.

2.        Low noise and loss,good heat dissipation performance,strong loading ability.

3.        good moisture proof performance,it can run with 95% relative Humidity.

4.        Low value of partial discharge,can guarantee long term safety operation in working voltage

5.        It can increase 40~50% of rated capacity shortly in forced air cooling.

6.        Good insulation performance,high tolerance for lighting impulse level,and strong ability to bear sudden short circuit. 

7.        It is high mechanical strength and good thermal stability.Because of rational combination for Insulation material,it can obtain the same temperature expansion coefficient with copper conductor.

8.        The computer temperature controller automatic monitoring and protection provides reliable safeguard for transformer's safety operation

9.        It is strong ability of flame retardant and automatic flameout.It can install in load center.

Product application scope:High-Rise Building,Commercial center,City  square,Hospital,School,Airport,Station,Seaport,Underground,Power station,Oilfield,Chemical Industry,Tunnel and so on.
