China Manufacturer S9 S11 TM TMH Oil immersed power transformer low price high quality

Products Range

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 oxygenfree copper lines and it adopts multilayered

drum type structure. All fasteners have been processed with special treatment to prevent them from loosening.

Reliable Structure

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.

Excellent Materials

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.
