Advantages

 

  • Lower operating cost over Liquid-filled
  • No additional fireproofing or venting
  • Long life expectancy
  • Smaller, lighter easy to maintain

 

The transformer has following characteristic:


1,Grade C insulation (higher than grade H) , has good heat emissionbig overload capacity, which can work without wind machine for longtime under 130% overoad, and be full load with out compulsive windcool withoutcapacity descending (descendance) under lP45 condition.
2,Prefect safe and resistance to fire operating can be combustingfor long period under 800℃ and without smoke.
3,Strong resistance to thermal shock, (can be full load immediatelyat-50℃).
4,Complete waterproof and airproof.
5,No partial discharge.
6,Good hydrophobility and good resistance to alkalinecauterization and fundal influence.
7,Environmental protection: low noise, no deleterious gas, easytodecomposition.
