1, with the mixer by mixing the inner layer of plastic, the middle layer of plastic and the outer plastic; with extruder inner tubing, coated with a release agent in the soft core or hard core (liquid nitrogen Frozen method can not die) 2, the calender press into the middle layer of plastic film, plus isolation agent winding process requirements and cut into the provisions of the width 3, with the inner core tubing winding machine or weaving machine on the winding or weaving Copper wire or copper wire rope, winding machine or weaving machine at the same time in the middle layer of plastic film will be wrapped in each of the two layers of copper wire or copper wire rope, wound wire at the beginning and end banding (some early winding machine to be pre-plated Copper wire for prestressing stereotypes processing) 4, once again in the extruder coated with the outer layer of plastic, and then wrap the lead or cloth vulcanized protective layer 5, sulfide or salt bath curing

6, the last to remove the curing layer of protection, out of the die, withhold the pipe joints, sampling pressure test.
