Part Ⅱ: Product Features

1. Low Noise

① Normal operation noise is less than 58 decibels

② Selecting high quality core material, choosing suitable magnetic flux density and self-vibration frequency of core.

2. Low Loss

① Adopt magnetic leakage calculation and take effective measures to reduce stray losses, while effectively preventing local overheating and reducing the temperature rise of winding hot spots.

② Reasonable selection of coil wires to reduce winding eddy current loss, stray loss and other additional losses.

3. Low Partial discharge

The solid insulation made of high quality resin and glass fiber has high electrical strength and the partial discharge is very small and can be controlled within ≤5pC

4. Flame retardant

① Under the burning of high temperature open flame, transformer almost no smoke generated

② Burning grade F1

5. High overload capacity

Can be operated for long-term cyclic load or temporary emergency type load.

6. Strong short circuit resistance

① The high voltage coil adopts resin casting structure, with good mechanical strength.

② Adopting pulling plate and gasket pressing structure, which makes the whole body stable and firm.

Part Ⅲ: Structure Feature

1. Iron Core

The iron core is made of high quality, cold-rolled, granule-oriented silicon-steel sheets and machined with completely automatic cutting line, superposed with 45° six-level bias seams. Core column adopts special banding technique, the surface of iron core is painted with the special rustproof coating to resist humidity and rust, which can effectively reduce the no-load losses, no-load current and iron-core noise. Facilitated with six sets of cutting lines for iron core such as, Soenen from Belgium.

2. Winding

F-class insulation HV winding: it is made of lacquered wire. With hardness ranges from 120 to 210 Mpa. The insulation material is a composite of silicon micro-powder and epoxy resin, featuring high performances of good thermal shock resistance, fire resistance, no emission of hazardous gases, good heat dispersion and low winding temperature rise.

H-class insulation HV winding: it adopts NOMEX paper wrapped flat copper wire and continuous winding process. The winding made after dry treatment by VPI vacuum pressure device, several times impregnated in special H class insulating paint.and baking features high mechanical strength, good heat dispersion.

LV winding: LV winding is mainly made of foils. It adopts interior argon gas protection welding,with high precision and reliability as no external welding joint. It solves the winding turns imbalance , effectively improves thermal performance and enhance short circuit withstanding capability.
