Structure

Iron core

The iron core is made of high-quality grain-oriented cold-rolled silicon steel sheet with high magnetic permeability, 45" full-inclined stepping seam, the iron core adopts a special square tube pulling plate structure, the core column is bound with insulating tape, and the iron core surface is coated with special resin. Moisture-proof and rust-proof, effectively reducing no-load loss, no-load current and iron core noise.

Safe, flame retardant and fireproof, no pollution, can be directly installed in the load center.

Maintenance-free, easy to install, and low overall operating cost.

Good moisture-proof performance, can operate normally at 100% temperature, and can be put into operation without pre-drying after shutdown.

Low loss, low partial discharge, low noise, strong thermal capacity, equipped with a complete temperature protection control system, providing reliable guarantee for the safe operation of the transformer.

High reliability. According to the operation research of the products that have been put into operation, the reliability index of the products has reached the international level.

Temperature control device

The transformer adopts BWDK series signal thermometer, and the temperature measuring element is embedded in the upper half of the low-voltage coil, which can automatically detect and display the working humidity of the three-phase coils. And has over temperature alarm and trip function.

Foil coil

The low-voltage winding adopts a whole section of copper foil, and is wound on a special low-voltage foil winding machine together with the F-class turn insulation. Foil coils can better solve the problems of low voltage and high current coil winding products with large short-circuit stress, unbalanced ampere-turns, poor heat dissipation effect, winding helix angle and unstable manual welding quality. At the same time, the winding ends of our company are potted with resin, cured and formed to prevent moisture and fouling.
