Features

+Safe, flame retarant, pollution-free, and available to be installed directly in the load center;
+ Maintenance-free, easy to install and low integrated operation cost;
+ It has good moisture-proof performance and can operate normally under 100%humidity;
+ Low loss, low partial discharge, low noise, strong cooling ability, and 150%rated load operation under forced air cooling conditions;
+ It is equipped with perfect temperature protection control system to provide reliable guarantee for transformer safe operation;
+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 advanced level;
+The transformer adopts BWDK series signal thermometer. The temperature measuring element is embedded in the upper part of the low-voltage coil. It can automatically detect and display the working temperature of the phase coil, and has the functions of over-temperature alarm and trip.
+Low voltage winding is made of pure cooper (or aluminum)foil and manufactured on special low voltage foil winding machine, with turn insulation of class F. Foil coil can solve the problems of low voltage, high short-circuit stress of high current coil winding products, ampere turn imbalance, poor heat dissipation effect, large spiral angle of winding, unstable quality of manual welding and so on. At the same time, the winding end of our company adopts resin for sealing, solidification, moisture-proof and anti-fouling. Copper bars are welded automatically by argon arc welding.
