The core of the dry-type power transformer adopts high-magnetic conductivity, high-quality grain-oriented cold-rolled silicon steel sheets with 45° full-slant step-in joints. The core adopts a special square tube pull plate structure, the core column is tied with insulating tape, and the core surface is coated with special resin to prevent moisture and rust, which effectively reduces no-load loss, no-load current and core noise. It is a dry-type transformer with strong electrical strength and mechanical strength. It is an excellent product for urban power grid transformation, especially suitable for important places such as high-rise buildings, airports, power stations, and commercial centers that require fire prevention, explosion prevention, and moisture prevention.
