The 11kV dry type transformer is made with abroad advanced technology.it includes the following characteristics:

1. Low local discharge
    As the coil is cast in vacuum state, the air bubble produced in coil can be prevented efficiently, the local discharging value fully accords with relative national standard.
2. Strong capability of lightning impact
    The lightning impact voltage that affects the insulation of transformer windings along the initial voltage distribution of windings, the foil type windings initial voltage distribution approaches to linear one,therefore, the transformer manufactured by us has good ability to resist the lightning impact.
3. Strong ability to resist short -circuit
    The width of copper foil of LV windings that is the reactance height, LV current is supplied according to be the requirement for ampere turns balance among windings, HV/LV windings axial force caused by short circuit tends to zero.
4. Good performance of anti-drying crack
    The transformer manufactured by us is made of packing type resin and designed into the structure of full copper oil, the coefficient of insulation material is the similar to the that of thermal expansion of copper conductor, so the coils can be prevented cracking efficiently. The transformer has been done kinds of anti-crack tests, such as cold/hot alternation test, thermal impact test, rapid aging test, etc, and the test result demonstrates that our technology can meet the requirements of service occasions like low temperature, high temperature and large range of variable temperature, as well as anti-crack after the transformer runs for a long time.
5. Strong over-load capability
    If the transformers of same capacity whose load consumption is equal, the sectional area of copper foil will be increased correspondingly, and the volumewill be extended with the sectional area that requires more packing resin, therefore, both the thermal capacitive property of windings and short -time over load capability of  transformer are quite strong.
