Description

Technical Parameters

Henan Gnee New Material Co., ltd. is one of the leading manufacturers and suppliers of three phase oil immersed transformers in China, also supports customized service with low price. Welcome to buy discount three phase oil immersed transformers for sale here from our factory. If you have any enquiry about pricelist, please feel free to email us.

 

GNEE New Material three-phase transformers

The S -M series three-phase oil immersed transformer adopts full oil filled and sealed corrugated oil tank. The oil tank shell adapts to the oil expansion performance with its own elasticity and meets the heat dissipation requirements. The body adopts a new insulation structure to improve the short-circuit resistance; the core is made of high-quality cold-rolled silicon steel sheets; the high-voltage and low-voltage windings are made of oxygen free copper wires and adopt multi-layer cylindrical structure; all fasteners adopt special anti-loosening treatment.

Dry Type Oil immersed Transformer Product Characteristic

  1. The iron core is made of silicon steel sheets with high quality, high performance and high magnetic conductivity, with low no-load loss.
  2. High voltage winding adopts layer structure. Low voltage winding 500KVA and below is layer type, 630kVA and above products adopt new spiral type. High mechanical strength, balanced ampere turn distribution, strong short circuit resistance.
  3. The positioning structure is added to the body to avoid displacement during transportation. At the same time, all fasteners are equipped with fastening nuts to ensure that the fasteners are not loose during long-term operation.
