Product Description

Low Loss Hv Oil-Immersed 11kv 33kv Electrical Power Transformer;11kv Distribution Transformer Pole Mounted Transformer and Pad Mounted Transformer


Product introduction

This product conforms to the national standard gb1094.1-2013 power transformer and GB / t6451-2015 three phase oil immersed power transformer technical parameters and requirements. This product has adopted a series of major reforms in material, technology and structure, so that the electrical performance of the product can reach the advanced level of similar products. With the characteristics of high efficiency and low consumption, it can save a lot of power consumption and operation costs, and has remarkable social benefits. It is a new product promoted by the state. It is also one of the more popular products for users.









 

Main Functions And Features

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 heat proof 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.
