Product features:

1, compact structure, small volume, convenient installation, flexible

2, fully insulated, fully sealed structure, safe and reliable, maintenance-free, reliable protection of personal safety;

3, the high voltage side adopts double fuse protection, wherein the fuse of plug-in fuse is double sensitive fuse (temperature, current), and the backup fuse is current limiting fuse, which reduces the operation cost

4, high voltage incoming line adopts cable connector structure, fully insulated; It can be used for both ring network and terminal, which is very convenient for conversion and improves the reliability of power supply

5, transformer for three-phase three column or three-phase five column structure, iron core using ladder joint process or coil core process, low noise, low loss, short circuit resistance and overload capacity

6. Adopting the special process of vacuum drying and vacuum oiling, our company extended this process which was used for 110kV products to 10K ∨ products to provide strong guarantee for improving product quality.

7. The box body can adopt anti-corrosion design and special spray painting treatment according to the requirements of the operation environment, with "three anti-condensation" function, anti-salt fog, anti-mold function, and can meet the anticorrosion requirements of high temperature and high humidity environment.
