Series SC(B)9,grade 33KV Three-phase,50~2500KVA dry-type distribution transformer
Product Details
9.It is strong ability of flame retardant and automatic flameout.It can install in load center.
8.The computer temperature controller automatic monitoring and protection provides reliable safeguard for transformer's safety operation.
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
6.Good insulation performance,high tolerance for lighting impulse level,and strong ability to bear sudden short circuit.
5.It can increase 40~50% of rated capacity shortly in forced air cooling.
4.Low value of partial discharge,can guarantee long term safety operation in working voltage.
3.Good moisture proof performance,it can run with 95% relative Humidity.
2.Low noise and loss,good heat dissipation performance,strong loading ability.
(1).Advanced and reasonable structure,small volume,light weight,convenient installation,maintenance-free and good economy.
