Technical scheme: a kind of high tensile is cold-resistant curl cable, comprises conductor layer, semi-conductive cloth tape layer, semiconductive internal shield, ethylene propylene rubber insulated layer, insulation screen, braid, stranding belting layer, inner covering, outer jacket and flexible steel cable;
Cable core adopts three insulated wire cores and three ground connection cores, and interval is stranded successively forms, and is tightened by stranding belting layer band; Conductor layer in described insulated wire cores first restraints conjunction in the same way by superfine tinned copper wire, more in the same way again strand form; Be surrounded with semi-conductive cloth tape layer outside described conductor layer, described semi-conductive cloth tape layer adopts three-layer co-extruded mode to be extruded with semiconductive internal shield, ethylene propylene rubber insulated layer and insulation screen successively outward, and described insulation screen is coated with braid; Described wire core is made up of zinc-plated stranded conductor layer, semi-conductive layer and braid.
Be extruded with inner covering outside described stranding belting layer, outside inner covering, be extruded with outer jacket, between described inner covering and outer jacket, lift flexible steel cable.
As optimization: described conductor layer adopt superfine tinned copper wire in the same way synnema cross suitable compressing mold structure and making together again after multiple in the same way strand, twisting pitch again controls at 10 ~ 12 times, presses die size and is less than stranded conductor size 0.3 ~ 0.8mm.
As optimization: described braid adopts tinned copper wire and PBO combined knitting to form.
As optimization: lift four strands of extra flexible wire ropes between described inner covering and outer jacket.
As optimization: it is the semiconductive material of base-material that described semiconductive internal shield and insulation shielding layer material are with ethylene-propylene rubber.
As optimization: the material of described inner covering and outer jacket is TPU elastomeric material, resist cold and reach-55 DEG C.
Beneficial effect: the utility model conductor layer is by first left-hand synnema (synnema pitch is not more than 18 times) of superfine tinned copper wire, left-hand twists again again, twisting pitch again controls at 10 ~ 12 times, and pressed by the mould that presses of line outlet, thus ensure the little and super softness of conductor smooth rounding, external diameter, improve cable electrical insulation property, avoid drawing greatly because of conductive surface gap puncturing, tin layers can prevent cable corrosion, insulation screen adopts tinned copper wire and the composite braided layer of PBO outward, except preventing electromagnetic interference, the tensile property of cable can also be improved, avoid because frequent stretching causes core impaired, cracking phenomena, be arranged on the stone dead wire between interior oversheath, increase tension effect, the mechanical strength of further raising cable, interior oversheath all adopts TPU elastomeric material, cable is made to have excellent softness energy, mechanical performance, cold tolerance (-55 DEG C), ageing properties etc., cable long service life, can for a long time in frequent rolling, longitudinal stretching, direct sunlight, day and night temperature is large and stand the marine harbour of salt air corrosion and other field uses.
