3.4. GB/R1094-1996 power transformer

3.5. GB4208-1993 outer shell protect grade(IP code)

4/ performance characteristics

4.1 Safety, fireproofin, non- polluter, directly used in loadcenter.

4.2 High mechanical intension.

4.3 Low loss, low noise, the obviously save energy,free from themaintenance

4.4 Strong ability of spreading hot and loading, and which theywill be raised the capacity while forcing the breeze.

4.5 Good function of defending moisture which make they suitablefor in high degree of humidity and other bad environments.

4.6 Providing with the perfect temperature examination and theprotection systems and adopting the intelligence signal temperaturecontrol system, can monitor and cruise back to show automaticallythe each work temperature of three-phase winding series;furthermore, can start automatically, stop the breeze machine, andreport to the police to jump.

4.7 Small size, light weight, little covering space, lowexpenses.
