The conductor Semi-Conductive Layer, XLPE insulation and the insulation Semi-Conductive Layer are extruded simultaneously in one process using triple extrusion method (Continuous Vulcanization Line). Triple extrusion method not only assures clean interfaces between the insulation and stress control layers, but also assures a construction free of Partial Discharge with high operational reliability.
导体半导电层、XLPE绝缘和绝缘半导电层在一个过程中使用三重挤出法(连续硫化线)同时挤出。三重挤压法不仅确保了绝缘层和应力控制层之间的清洁界面，还确保了结构不会发生局部放电，具有较高的运行可靠性。
