5. Structure Feature

  • It is organic insulation type product. The external insualtion is silicone rubber petticoat.
  • Electric field evnely distributed, partial discharge small amount and stable, small dielectric loss.
  • The current ratio can be changed easily by changing the connection method in shielding enclosure to facilitate the realization to series or parallel connection.
  • The grading cover which is aluminum alloy casting formed and the cabinet which is stainless steel plate drawing formed, use DACRAL(Zinc/Chromate coatings) for resistance to corrosion, which gives a high degree of corrosion resistance.
  • All parts, such as stainless bolts, nameplate are rust-free all the time.
  • The product has no oil, no ceramic, no gas.
  • Barely need for maintenance. Just need to measure once capacitance and dielectric loss factor every 2~3 years.
