It is further characterized in that:
All heart yearns are by the stranded formation stranding of the cage winch of synchronous back twist, and limit stranding limit back twist, eliminates the twisted wire stress that in twisted wire process, wire rod produces;
Described lapping layer is specially polytetrafluoroethylene band structure;
The insulating barrier of described heart yearn is specially semihard flame-retardant PVC material and makes;
The conductor of described heart yearn is specially the multiple twisted wire of soft copper;
Preferably, described conductor by filament diameter be 0.08mm naked copper in the same way again twist material press stranded making;
Stranded cotton thread described in every root is specifically made by multiply cotton thread is stranded, increases the pliability of wire rod;
The material of described sheath is specially semihard flame-retardant elastomer wearable PVC;
Preferably, described heart yearn has eight, and it is according to the stranded formation stranding of the layout of 1+7, and seven heart yearns being positioned at outside are surrounded on a heart yearn at center, are furnished with stranded cotton thread in the gap between the described heart yearn in outside and central core.
After adopting structure of the present invention, stranded cotton thread is furnished with in the gap of the stranding formed due to heart yearn, which raises overall pliability, make entirety can adapt to various environment fast, the existence of braid improves the anti-electromagnetic interference capability of cable, and because the skin of stranding is coated with lapping layer, braid, sheath successively, it is durable in use, do not ftracture, continuous core, long service life, guarantees that the long-term safety of equipment is run.
Accompanying drawing explanation
Fig. 1 is the structural representation sketch of specific embodiments of the invention;
Title in figure representated by sequence number is as follows:
Sheath 1, braid 2, lapping layer 3, central cavity 4, heart yearn 5, insulating barrier 6, conductor 7, stranded cotton thread 8.
Embodiment
The industrial cable of a kind of highly-flexible abrasion resistant fire blocking drag chain, see Fig. 1: it cross section comprising that ecto-entad is arranged in order is circular sheath 1, braid 2, lapping layer 3, central cavity 4 is formed in the inwall of lapping layer 3, stranding is provided with in central cavity 4, stranding comprises at least one group and controls heart yearn, often organize control conductor and comprise at least one heart yearn 5, every root heart yearn 5 comprises outer field insulating barrier 6, the conductor 7 of internal layer, the stranded formation stranding of all heart yearns 5, stranded cotton thread 8 is furnished with in the gap of the stranding that heart yearn 5 forms, the peripheral ring bread of stranding is covered with lapping layer 3.
All heart yearns 5 are by the stranded formation stranding of the cage winch of synchronous back twist, and limit stranding limit back twist, eliminates the twisted wire stress that in twisted wire process, wire rod produces;
Lapping layer 3 is specially polytetrafluoroethylene (PTFE) band structure,
The insulating barrier 6 of heart yearn 5 is specially semihard flame-retardant PVC material and makes;
The conductor 7 of heart yearn 5 is specially the multiple twisted wire of soft copper, and conductor 7 is preferably that 0.08mm naked copper twists material in the same way again and presses stranded making by filament diameter, makes heart yearn 5 have the characteristic of highly-flexible;
The stranded cotton thread of every root 8 is specifically made by multiply cotton thread is stranded, increases the pliability of wire rod;
The material of sheath 1 is specially semihard flame-retardant elastomer wearable PVC.
Wherein in order to improve drag chain performance and the rub resistance of wire rod, the materials'use semihard flame-retardant PVC of the insulating barrier 6 of heart yearn 5 makes, and heart yearn 5 back twist is twisted together;
In order to improve wire rod pliability, wear-resistant tow chain and flame retardant effect, stranded cotton thread 8 is made by multiply cotton thread is stranded, and lapping layer 3 uses PTFE to be with, and sheath is made up of semihard flame-retardant elastomeric material;
