Technical characteristics of dry - type transformers

1. Anti-short-circuit ability, low-voltage winding copper foil is the height of the high-reactance, low-voltage current according to the winding between the ampere-turn balance requirements match, high and low voltage winding short circuit caused by the axial force is almost zero.
2. Overload capacity, if the same capacity of the transformer load loss is equal, then the corresponding copper cross-sectional area will be larger, the volume increases, the amount of filler resin, so the thermal capacity of the winding large, farady transformer short- Overload capacity.
3. Good anti-cracking performance, dry-type transformers using filler-type resin and copper foil structure, insulation and copper conductor thermal expansion coefficient of the most similar to effectively prevent the coil cracking. In the arc under high temperature combustion, does not produce any toxic gases.
4. Low noise, the transformer to take some special structure and design, making the noise greatly reduced, the overall noise level than the national professional standard noise value of 10-13dB (A) or more.
5. Lightning impulse withstand ability, lightning impulse voltage along the winding of the initial distribution of dry-type transformer winding insulation damage.
6. Flame-retardant characteristics, the use of filler-type resin casting process is conducive to environmental protection, Amorphous Metal Distribution Transformer with maintenance-free, moisture protection, anti-heat, flame retardant and self-extinguishing characteristics.
