220KV Oil Immersed Power Transformer

Henan GNEE Electric Co., Ltd. is one of the most reliable manufacturers and suppliers of 220kv oil immersed power transformer in China. If you're going to buy customized 220kv oil immersed power transformer made in China, welcome to get quotation from our factory. Quality products and reasonable price are available.

The 220kV oil immersed power transformer produced by our company is self-developed based on the digestion and absorption of advanced technology at home and abroad, and is tailored to the characteristics of China's urban and rural power grids. This series of products has outstanding characteristics of low loss, low noise, and no need for hanging cores. Its safety, economy, and other aspects have extraordinary innovation, making it a first-class technology product in China.

Specification

1. With the quality grain-oriented cold-rolled electrical steel, the iron core adopts whole-titled nonporous structure. Using the low magnetic steel sheets as drawing board, the core is connected with the upper and lower clamping fixtures tightly form a steel framed structure so as to obtain the smaller on-load loss and lower noise.
2. Based on the transformer capacity, the windings adopt cylinder,spiral orcontinous structure, and 110KV or higher grade windings,entangled or internal shielded structure so as to improve effectively the distribution of impulse voltage. For the purpose of reducing the additional loss of windings,the conductors are of position-changing or composite type. To use a computer to simulate and calculate the impulse characteristics of electric filed and windings shall gurantee electic features and impluse strength of windings. To take effective measures technologically will make sure their safe and reliable operations.
3. Entirely round insulating pressing plates are used for the holding down of transformer body. As far as the complete set of technique is concerned, the windings are assembled in a intergrating manner to improve the reliabilty of products.

4. The oil tanks are of bell-jar structure,with the tank walls to be welded with folded plate stiffening angles, thus improving the mechanical strength of tank. In order to lower the stray loss of trasformer, large sized transformer are equipped with magnetic shield on the inner walls of tanks.

5. In order to prevent the body of transformer from displacing in the course of transportation, the transformer body and oil tank are provided with positioning device. The oil storage tank is of termatically sealed tyoe to separate the oil from atmospphere so as avoid aging and dampening of the oil. The ends are installed on the top of tank so as to guarantee safety operation of products.

1.High pressure transformer, use Japanese Toshiba analysis software and our company special calculation andvalidation procedures to the transformer core, winding. implement body, lead, fuel tanks, etc, Parts of the optimal design and carry on the omni - directional validation, ensure product performance. Superior process equipment.

elaborate material selecting and efficient manufacturing.making the transformer has small volume, light weight,low loss, low partial discharge, low noise characteristics, the product quality is superior, energy conservation and environmental protection, easy installation and maintenance, reliable operation and effectively reduced products running costs.

2.The company product through national transformer quality supervision and inspection center short-circuit withstand ability and all type test routine.

3. This product is stable, reliadle, economic, environmental protection, applicable to the characteristics of generator, transformer substation, large mining petrochemical enterprise etc.
