Introduction:
Our transformers had exported to more than 50 countries in the world up to 200mva 230kv, we offers a complete range of power and distribution transformers designed to grant the reliability, durability, and efficiency required in utility, industrial, and commercial applications. QingZhong is a major transformer manufacturer throughout China offers both liquid-filled and dry-type transformers as well as services for complete life-cycle support, including replacement parts and components.
1. The low-voltage winding is of cylindrical or spiral structure, with high mechanical strength and good short-circuit resistance.
2. The corrugated oil tank is adopted to replace� the oil conservator. The oil tank cover and the oil tank are all-welded along the edge or fastened with bolts, thus prolonging the service life of the transformer oil.
3. After oil removal, embroidery removal, and phosphating treatment, the product is sprayed with three times of primer and one time of finish paint inside and outside. The product is salt fog proof, damp heatproof, and fungus� proof, which can meet the special requirements of metallurgy, petrochemical system, and wet and polluted areas. It is beautiful� and reliable.
4. The transformer oil tank is� fully sealed, and� equipped with� pressure reducing valve, signal thermometer, gas relay, etc according to the standard requirements to ensure the safe operation of the transformer.
5. This series of products are beautiful in appearance, small in size, and can reduce the installation area. It is an ideal maintenance-free distribution product.
