Necessary test equipment for power equipment inspection and preventive test
Inflatable test transformer is a necessary test equipment for power equipment test and preventive test.With the development of China's power industry，The requirement of voltage grade of test transformer is higher and higher，And the traditional oil-immersed test transformer，No matter in the volume and weight or in the performance are increasingly unable to meet the requirements of field work.
With the progress of basic science research in China，advanced material，Application of new process，The new medium sulfur hexafluoride gas is introduced into the application field of power equipment.Because of the excellent insulation and arc extinguishing performance of sulfur hexafluoride gas，And incombustibility，It is widely used as a new insulating medium.
Our company has been working hard for many years，Inflatable ac test transformer is studied successfully，This series of inflatable test transformer is compared with traditional oil-immersed lightweight test transformer，You lose weight20%－60%(It depends on voltage and capacity level)，And no oil pollution，The voltage grade of single inflatable test transformer can be reached300kV.Due to the inflatable test transformer with a new production process，The technical performance of the product has been greatly improved，Especially suitable for field work and frequently moving working conditions.

1.The appearance of the product shall be subject to the actual product，If there are any changes in technical parameters and models，without prior notice.If there is theft or copying，Legal responsibility will be pursued.
1、The inflatable test transformer is small in size，in light weight(It is 40%-65 lighter than the same grade oil-immersed transformer)
2、spotless，greaseless，There is no need to maintain
3、Free from adverse weather and environment，The field transport should be stationary and can be tested
4、The insulation strength is obviously higher than that of oil-immersed transformer，Minimal corona
