product brief introduction

AC hipot tester series Testing Transformer is power plants power supply bureau and research institutions and other users to do the AC voltage test basic test equipment by the standards of the State Bureau of Quality Supervision for a variety of electrical products electrical components insulation material dielectric strength test etc. the insulation level assessment of products under the provisions of the voltage insulation defects were found in the sample and measure the ability of over-voltage.

AC HV Testing Transformer Classification:
There are four kinds of high voltage testing transformer according to the medium points:
1. Oil-immersed high voltage transformer test: large capacity cheap convenient maintenance mainstream products.
2. Inflatable high voltage test transformer : interrupter resistance and light weight.
3. Dry type high voltage testing transformer: light weight light volume can run backward price expensive.
4. Series type high voltage testing transformer: small volume low voltage light weight easy to transport and install.

product features

1.HV bushing was first time made

2.Between the bushing and the oil tank is completely isolated and all connection parts adopted

imported “O” type sealing ring seal so we completely solve the common problems of

transformer leakage.

3.Sleeping core type design effectively improve seismic resistance.

4.Before delivery 24 hours upside down testing and no leakage.

5.All products’re passed through 1.1 times induction withstand voltage testing.

6.Pure famous oil-immersed insulating medium.

7. HV & LV cables are made by high strength polyester oxygen free copper enameled wires.

8.The core was adopted with new WISCOtwo silicon cold rolled silicon steel strip
