Resin insulated dry-type transformer is safe, flame retardant and pollution-free, and can be directly installed in the load center. It is maintenance-free, easy to install, low in comprehensive operation cost, low in loss, good in moisture-proof performance, and can operate normally under a humidity of 100%, making it able to be put into operation without pre-drying after shutdown. It has low partial discharge, small noise, strong heat dissipation capability, and can run with 120% rated load under forced air cooling condition. It is equipped with perfect temperature protection and control system, providing reliable guarantee for safe operation of transformer with high reliability. According to the research on the operation of more than 10,000 products that have been put into operation, the reliability index of the product has reached the international advanced level.

Core
The iron core is made of high-quality oriented cold rolled silicon steel sheet material, with 45-degree fully inclined seam structure; the core leg is bound with insulating tape, sealed with insulating resin paint on the surface to prevent moisture and rust; clampings and fasteners are surface treated to prevent rust.
Using the environment
Ambient temperature: - 5 ºC ~ + 40 ºC
The most thermidor average temperature + 30 ºC
The hottest year average temperature 20 ºC +
The altitude does not exceed 1000 m
The power supply voltage waveform similar to sine wave
Three-phase power supply voltage should be roughly symmetric
No obvious the filth of the installation environment
Indoor use
