50-1800 KV non-partial power-frequency testing transformer:

1)Packaged equipment can be easy combined.There are adequate series of voltage capacity,and the capability of them is powerful. 

2)Non-partial discharge epoxy insulation pail is successfully invented.It could reduce the partial discharge ,and it can keep ahead inland.

3)High quality DQ130-30 magnetic partial-directing silicon sheet and 45' completely mitered sheet are used.Change rate of the wave of products and non-load current is the smallest inland.

4)Impedance voltage is lower than the determination of the national standard.

5)Auto-control technique and computer (optical fibre) controlling technique make the strong anti-interference ability.

6)The reliable fast-electron protecting installation is used.
