Description

technical field [0001] The invention relates to an inner insulating wire tube and a manufacturing method thereof. Background technique [0002] In the cable laying of rail transit vehicles, the difficulty of cable threading and the insulation performance after laying need to be considered to a large extent. The main body of the traditional cable threading pipe is a welded metal pipe. The single-layer metal pipe can shield the electromagnetic waves radiated from the conductor and at the same time shield the electromagnetic waves intruding from the outside, so that the cable transmission signal is not distorted. However, due to the welding of metal pipes, it is impossible to ensure that the welds can face upward during construction, and the cables are easily pulled and worn during threading, which affects the insulation and has serious hidden dangers. [0003] Due to the poor wear resistance and heat resistance of the current inner insulating wire tube, the thickness of the i...
