630KVA-11-0.4 Three Phase Low Loss Oil Immersed Power Distribution Transformer

Product Overview

The three-phase oil-immersed distributing transformer applies new type insulatingstructure and makesshort-circuit resistance strong The iron core is made of high-qualitycold-rolled silicon-steel plate. High-voltagewinding group is made up of high-qualityoxygen-free copper lines and it adopts multilayered drum typet sructure. All fastenershave been processed with special treatment to prevent them from loosening.As high-tech product that promoted bv the county, the product has many advantagessuch as high efficiency, low loss. lts social benefits are remarkable that it will save muchof electricity consumption and operating cost.

Excellent Materials

Because we use oxygen-free copper lines of lower resistivity, which will becomesmoother and burr-free after series of additional sudace treatment so the load loss ofour transformer is lower and the electric performance 1S better.
We use high-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
We use high quality wooden laminating Insulation pieces which won. tsplit or moveeven under the Influence of short circuit.
We use thoroughly filtrated transformer oil containing less water gas and lmpuritieswhich makes our transformers work better.
We use high quality rubber sealing material which can prevent the transformers fromaging or leakage.
All raw materials has passed the quality testing and all the raw material factoties haspass through the national standard IS09000inspection
