(5) total stranding: the combination of strengthening core is placed at center, and surrounding places multiple groups line to combination, according to a constant pitch and Direction is twisted to form cable core;
(6) outer wrapping layer is formed using polyester belt outside cable core, the neoprene rubber of irradiation crosslinking type is used outside outer wrapping layer Glue extrudes to form inner sheath, is woven outside inner sheath using aramid fiber yarn, forms braiding enhancement layer, outside aramid fiber yarn braiding enhancement layer It extrudes to form oversheath using irradiation type neoprene;The disposable irradiation after the completion of extruding of interior oversheath.
Tensile wear-resistant tow chain communication cable in harbour provided by the utility model, products obtained therefrom have tension, wear-resisting, resistance to smelly The performances such as oxygen, ultraviolet resistance, flexibility and the performances such as good information transfer capability are remained in use, use It is long-term to can satisfy Large-scale Mobile equipment under the environment such as harbour, harbour, oil platform for the convenient, excellent characteristics such as the service life is long Frequent drag chain stretches the particular/special requirement of friction, to greatly extend the service life of mobile device.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The technical solution of the utility model is described with reference to the drawings.
As shown in Figure 1, harbour tensile wear-resistant tow chain communication cable, the conductor 1 including being equipped with insulating layer 2, two conductors 1 Pair twist forms one group of line pair, and line opposite side gap fills a packing 3;Line is externally successively arranged wrapping layer 4, foil shielding layer 5, plating Tin proof copper-wire braided shielded layer 6;A drainage thread 7 is placed between foil shielding layer 5 and tinned copper wire woven shield 6, is formed Line is to combination;It further include using aramid fiber thread reinforcement core 8, the aramid fiber thread reinforcement core 8 extrudes protective layer 9 outside, forms strengthening core Combination;Strengthening core combination is located at center, and the symmetrical more lines of surrounding are twisted to combination to form cable core;Cable core be successively arranged it is outer around Covering 10, inner sheath 11, braiding enhancement layer 12, oversheath 13.
