1. Low partial discharge


1)Reducing the electric field distortion, to ensure that the most concentrated part of its electric field strength is always lower than the initial field intensity discharge.


2)Increase angle ring at the presence of a strong centralized location.


3)Electrostatic panels turns to be new structure,strictly control the quality of their dressing and welding.



2. Strengthen anti-short circuit capability


1)Strict control high and low voltage winding ampere-turns balance.


2)Increase the winding shift winding, improve the efficiency and reduce harmonic.


3)All Winding cardboard pads use Weidmann, pre-unhair, dry, and dense processing, to keep the winding axis height.



3. Strong overload capacity and long service life

1). We strictly control the design of the top oil temperature and winding temperature rise, 5-7K under the normal standard of IEC.

2). Using the principle of twists and turns driven oil, set oil block circle within the winding.


4. Anti-leaking measures

1). Transformer tank has got flat roof, we purchase wide steel plate, to ensure that no patchwork).


2). Take 0.1Mpa plus pressure leak testing and 133Pa vacuum test on the fuel tank to check for fuel tank

leakage and strength assessment, to ensure adequate strength and non-leaking tank.

3). Vacuum valve, the valve body flange pre-installed on the transformer and without force.

Features & Advantages
1. Low loss, low noise and high reliability.
2. Excellent dynamic thermal stability and high over-load capacity.
3. Simulation analysis was carried out for the core mould design, thus to greatly reduce noise level. Simulated lightning impulse wave process was carried out for HV winding mould design, thus to greatly improve product's anti-lightning impulse capability.
