This porduct was developed by our company in 1975 to improve capacity between distribution line and earth by connecting the 2nd winding distribution line of insulation transformer and earth.
It uses polypropylene film which has excellent insulation ability and good quality capacitor paper as dielectric and contains specially produced composite oil to improve electric feature.
