H CLASS Oil-immersed Dry Type Transformer
PRODUCT OVERVIEW
It has long life expectancy and strong overloading ability. it can operate continuously at 120% of rated capacity, and it could also operate at rated capacity without forced cooling.
PRODUCT OVERVIEW
It has long life expectancy and strong overloading ability. it can operate continuously at 120% of rated capacity, and it could also operate at rated capacity without forced cooling.
It has very high safety and fire-prevention properties, without smoke generated when long-burning at 800℃.
It has excellent thermal shock resistance(with immediate full loading at-50℃).
100% waterproof sealing, excellent hydrophobicity, and moisture resistance.
After service life, the insulation materials and copper wire can be easily detached and recycled with no pollution to the environment.
