|
|
|
|
Product Feature;
|
1.Low loss,high econnomize on energy effect
2.Low rise temperature,prolong insulation natural life
3.Low noise,fall environment pollute. working noise very small.≤ 50db
4.High dependability,heighten products resist break out short circuit ability
5.Not need suspend core, not need maintenance.Prevent and delay aging,insulation damp of oil.boost up work dependability,general condition working not need maintenance.
6.Not leakage,good quality accessories.Choice fully sealed for aspecial purpose gas relay, Drang release valve etc.shell static spray-paint,endure use natural life long.
