Product Introduction
The three-phase oil-immersed distribution transformer produced by our company adopts a new insulation structure to improve the short-circuit resistance. The iron core is made of high-quality cold-rolled silicon steel sheet;
High-voltage windings are made of high-quality oxygen-free copper wire, and adopt multi-layer cylindrical structure; all fasteners are treated with special anti-loose treatment.
The product has the characteristics of high efficiency and low loss, which can save a lot of power consumption and operating costs, and has significant social benefits.
