Secondary winding in the bottom of tank, product has a low gravity center and good resistance to shock.
Main insulation is the oil-paper insulation structure with capacitance screen so the begriming voltage which voltage will create partial discharge is high and the products has a good resistance to switching impulse voltage.
Insulation can be wrapped mechanically to achieve high technical stability and good insulation stability
Multilayer limited sealing with non-exposed sealing structure to raise ageing resistance of sealing washer and extend product life.
Kerosene vacuum drying technical with capor phase heating is used to shorten drying period, to achieve complete dry, low dieelectric los and good insulation and thermal steady performance
Decrement anti-corrosion technique is used in the metal pants, example for tank and head, all the external fasteners are stainless steel standard pants, those make products no corrosion, and have a good anti-corrosion performance.
Full-automatic vacuum filing oil system with function of auto detecting leaking rate makes sure products sealing.
