Three phase 6.3kv 800kva Oil immersed OLTC Distribution Transformer
The three-phase oil-immersed distribution transformer applies new type insulating structure and makes short-circuit resistance strong. The iron core is made of high-quality cold-rolled silicon-steel plate. High-voltage winding group is made up of high-quality oxygen-free copper lines and it adopts multilayered drum type structure. All fasteners have been processed with special treatment to prevent them from loosening.
Spiral loops with longitudinal oil path to produce a better interior cooling effect; Improve the effectual support of the loop’s terminal face to strengthen the anti-short circuit electricity capability; New suspending structure and instrument-positioning frames to guarantee that the long distance transport and movement will be more reliable.
Oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
High-quality wooden laminating insulation pieces, which won’t split or move even under the influence of short circuit.
Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.
High-quality rubber sealing material, which can prevent the transformers form aging or leakage.

Main Function and features
It adopts radiator oil tank of corrugated sheet type or expansion type. As it doesn’t need oil conservator, the height of transformer is reduced, and as the transformer oil doesn’t contract with air, the oil ageing is retarded, thus prolonging the service life of transformer. The no-load loss of Model S10 M is 20% lower than that of Model S9-M, and S11-M is 30% lower than S9-M. The transformer are high in reliability, advanced in performances and rational in economical indexes. The oil tank is diversified in types and looks artistic and elegant.
