[0022] The specific operation is as follows: the outer wall of the cable inner core 1 is wrapped with a polyethylene insulating sleeve 2, and the material of the polyethylene insulating sleeve 2 is polyethylene, which can ensure good contact between the first filling layer 4 and the cable inner core 1, and eliminate the increase in surface electric field strength caused by the rough surface.
