This kind of transformer is made with overseas advanced technology. Its characteristics:
1) Good flame retardancy
The transformer has visible features such as free maintenance, moisture-proof, anti-damp and hot, flame-retardance, self-extinguishing, etc. , besides its stuffing type resin casting technology is good for environmental protection. The product has good ability to adapt to environment, on the basis of European HD464 standard, it reaches the environment class E2, weather-resistant class FC2, flame-retardance class F1. It can be widely used in fields or locations where service conditions are rather atrocious such as commercial area, under ground, power plant, steamship, offshore drilling platform, etc.
2) Low local discharge.
As the coil is cast in vacuum state, the air bubble produced in coil can be prevented efficiently, the local discharge value fully accords with relatively international standard
3) Strong capability of lightning impact.
The lighting 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
4) 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 the requirement for ampere turns balance among windings, HV/LV windings axial force caused by short circuit tends to zero
5) Good performance of anti-drying crack.
The transformer is made of packing type resin and designed into the structure of full copper foil, 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.
6) 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 volume will 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
7) Low noise
8) Low consumption
