10(15)KV Full-Sealed Oil-Immersed Power Transformers

S13-M Series

Summary

S13-M-type full-sealed oil-immersed power transformers performance indicators optimal energy-saving products, I produced the S13 product quality silicon steel, the new structure of the design and production process, hermetically sealed corrugated sheet tank structural design manufacture, beautiful appearance, small footprint, and significant economic benefits. S13-M-type transformers than the GB/T6451 standard no-load loss average 45% reduction in the average load loss reduced by 35%, operating costs decreased by 30% on average.

Features of products

S13 oil-immersed transformer low-voltage windings except small capacity using wire, generally cylindrical structure foil around the pumping of the high voltage winding multilayr cylindrical structure make the ampere-turns of the winding distribution balance, magnetic flux leakage small high mechanical strength, the ability of anti-short circuit.Each of the core and windings tightening measures, is height, low pressure leads fastening part with locknut, not hanging heart structure can withstand transportation of Britain earthquake.The core and the coil using a vacuum dry transformer oil filtering and oiling process, so that the transformer internal moisture and transformer oil moisture greatly reduced.The fuel tank using corrugated sheets, it has a respiratory function to compensate for temperature changes caused by the change in the volume of the oil, so the product does not have a conservator, also reduces the height of the transformer.Since the corrugated sheet substituted conservator, also reduces the height of the transformer.S13 oil-immersed transformer in normal operation does not require oil changes, greatly reduce the maintenance costs of the S13 oil-immersed transformer, while extending the life of the S13 oil-immersed transformer.
