Product Description

Henan New Electric Power Co., Ltd deals in the R&D, manufacturing and sales of various medium, high and Low Voltage Transformers and Transformer Accessories. The transformer accessories mainly include Buchholz Relay , Tap Changer , oil level gauge, butterfly valve, Moisture Absorber, pressure reducing valve, Cross Flow Cooling Fan, Bimetal Thermometer, Epoxy Resin Insulator, etc. New and old customers are welcome to purchase and customize.

Three phase Oil Immersed Transformer adopts fully filled sealed corrugated oil tank shell, which is a permanently sealed oil tank with its own elasticity to adapt to oil expansion. Oil immersed transformer has been widely used in various power distribution equipment.

Compared with the ordinary oil immersed transformer, the fully sealed transformer eliminates the oil conservator. The change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheets of the corrugated oil tank. The transformer is isolated from the air to prevent and slow down the oil deterioration and insulation aging, enhance the operation reliability, and is maintenance free during normal operation.
The transformer core is made of high-quality cold-rolled silicon steel sheets, which greatly reduces the no-load loss and no-load current, and the core is bound to ensure the tightness of the core and reduce noise.
The transformer is mainly composed of iron core, winding, oil tank, insulating sleeve, tap changer, etc.
a. Low voltage winding of oil immersed transformer adopts cylindrical structure; High voltage winding adopts multi-layer cylindrical structure to balance the ampere turn distribution of the winding, with small magnetic leakage, high mechanical strength and strong short-circuit resistance.
b. The iron core and winding adopt fastening measures respectively, and the fastening parts such as the height and low-voltage lead are equipped with locknuts, which can withstand the shock of transportation.
c. The coil and iron core are vacuum dried, and the transformer oil is vacuum filtered and injected to minimize the moisture inside the transformer.
d. The oil tank adopts corrugated sheet, which has breathing function to compensate the volume change of oil caused by temperature change. Therefore, the product has no oil conservator, obviously reducing the height of the transformer.

e. As corrugated sheets replace oil conservator, transformer oil is isolated from the outside world, which effectively prevents oxygen and water from entering and leading to the decline of insulation performance.
