Mining explosion-proof dry-type transformer

Product performance

This product adopts advanced German technology, combines the advantages of domestic and foreign isolation transformers, adopts full corrugated simple isolation, one-time formed special-shaped corrugated tube, and the shell is equipped with a guide heat dissipation plate, which has a unique and efficient heat dissipation effect. The insulation system of the body is H-level American Shebang NOMEX insulation material, non-encapsulated long-line wire, flat steel wire vertical winding structure, and adopts international advanced level special technology: VPI vacuum pressure impregnation, multiple impregnations of solvent-free insulating paint certified by UL in the United States, and then after baking and assimilation, the product has the characteristics of high electrical strength and good impact resistance.

The core is made of foreign high magnetic permeability material, oblong cross-section, non-punching H200 shrinkage and tensioning method, with a tight structure, firm and reliable.

 

Product features

The appearance is cylindrical, small in size, beautiful in appearance, light in weight, reliable in isolation performance, and the electrical performance indicators (compared with GB8286-1996 national standard: the average air loss is reduced by 1496, and the average negative tax loss is reduced by 10X) are ahead of similar domestic products, reaching the advanced level of similar international products, filling the domestic gap.
