[0011] Specifically, the insulating filler is made of polypropylene.

[0012] Specifically, the elastic adhesive filler layer is made of thermoplastic polyester elastomer material.

[0013] By adopting the above technical solution, the adhesive filler layer is specifically made of thermoplastic polyester elastomer material, which has high elasticity and good adhesion, making it easy to quickly shape the anti-bending metal wire mesh layer A and the anti-bending metal wire mesh layer B.

[0014] The beneficial effects of this utility model are:

It utilizes a PU shaping layer to wrap the inner wire body, achieving good shaping and ensuring the roundness of the wire cross-section. The insulating filler provides good insulation and evenly distributes the inner wire body. Dividing the wire into multiple bundles of metal cores improves stability during power transmission.

[0034] In use, the elastic filler layer 3 is made of thermoplastic polyester elastomer material, which has high elasticity and good adhesion, making it easy to quickly shape the anti-bending metal wire mesh layer A2 and the anti-bending metal wire mesh layer B4.

In addition, it has high tensile strength and will not break the wire during mechanical traction.
