Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

as shown in the figure, the drag chain cable comprises a cable core, a total shielding layer 2, a middle layer 3, a woven layer 4 and a sheath 5 which are sequentially arranged from inside to outside.

The cable core is formed by 4 signal lines 1 through mutual twisting, and each signal line 1 comprises a conductor 11, an insulating layer 12 coated outside the conductor 11 and a single shielding layer 13 coated outside the insulating layer 12.

The conductor 11 adopts silver-plated stranded copper wire to cladding ETFE high temperature fluoroplastics insulating material is as insulating layer 12, and transmission speed is superstrong, and the conductivity is high, single shielding layer 13 adopts PTFE membrane band, and the cladding is in the insulating layer 12 outside, not only has superior insulating properties, and toughness is good moreover, and coefficient of friction is low, and in the high frequency transmission process, to each signal line 1 self formation monomeric shielding effect, play the effect of shielding and keeping apart electromagnetic wave and radio wave interference.

The total shielding layer 2 adopts an aluminum foil mylar wrapping tape and is wrapped on the outer side of the cable core to form an overall shielding effect, and electromagnetic wave and radio wave interference can be fully isolated.

The middle layer 3 is made of LDPE materials, covers the outer side of the total shielding layer 2, and has super-strong impermeability, good waterproof performance, high and low temperature resistance, aging resistance, tensile strength and expansion rate.

The braided layer 4 is formed by combining and braiding bulletproof wires, tinned copper wires and flat silver-plated copper foil wires and is wrapped outside the middle tegument 3, the softness and bending and swinging performance of braiding are greatly improved by the combined braided layer, and meanwhile, interference of external electromagnetic waves, radiation sources of electrical equipment and radio waves is effectively isolated.

The sheath 5 is made of a modified PUR material, covers the outer side of the woven layer 4, and is made of a special wear-resistant tear-resistant modified PUR material, so that the tensile and wear-resistant effects are further improved.

The towline cable of the scheme has better flexibility, is wear-resistant in tensile strength, can better satisfy the frequently-bent working occasion of the towline cable, and is provided with multilayer shielding, so that the electromagnetic interference is reduced, the anti-interference performance is improved, and the stability and reliability of signal transmission are ensured.
