Description

A kind of high temperature resistant drag chain cable

Technical field

The utility model relates to cable production art more particularly to a kind of high temperature resistant drag chain cables.

Background technique

With modernization, intelligent continuous development, the continuous innovation of mechanical equipment；New equipment, new process will continue past Unmanned, intelligent direction development.Therefore, in the production and use process, mechanical equipment will be in high load capacity working condition；And As sophisticated equipment main energy sources: electric energy, transmission link service life in frequent moving process are always industry hardly possible Topic；It is frequently bended, rubs, squeezes, rubs because it will follow drag chain to rotate repeatedly especially for the drag chain inner cable that is laid in, if The problems such as being even broken according to common cable it is easy to appear insulation and sheath corrugation, damaged, breakdown.The mobile connecting line of tradition For the flexibility for guaranteeing cable, insulation and sheath mostly use polyvinyl chloride or rubber material；On the one hand, pvc material is because of it Mechanical performance and flexility are relatively poor, and contain a large amount of halogen in its molecule, with the raising of environmental consciousness, Wu Faman Sufficient product environmental requirement；On the other hand, rubber material processing technology is more complex, difficulty of processing is larger, required equipment and personnel work It is higher to make level requirement；Consider from cable performance and structure, usually guarantees the intensity of cable, the protective layer thickness in design It is thicker, but rubber material density compared with other CABLE MATERIALSs is larger, therefore product outer diameter is big, weight weight, be not easy to carry, install with Laying；And above-mentioned common used material maximum operation (service) temperature is only 70 DEG C~90 DEG C, is not able to satisfy the requirement of some high temperature applicationss.

Utility model content

The utility model aim be for overcome the deficiencies in the prior art and provide a kind of shock resistance it is strong, it is wear-resistant, Flexibility is good and the environmentally friendly high temperature resistant drag chain cable easily carried.

In order to achieve the above objectives, the utility model uses following technical solution.

A kind of high temperature resistant drag chain cable, including insulated wire cores, packing, conductor, insulating layer, separation layer, shielded layer and outer Sheath, the insulated wire cores and packing are round strip；The outer wall circular of the packing is cut outward is disposed with insulated wire cores； Conductor is provided at the center of the insulated wire cores；Insulating layer is enclosed on the outer wall of the conductor；Described in being circular layout Separation layer is provided on the outside of insulated wire cores；Shielded layer is provided on the outer wall of the separation layer；The outside of the shielded layer is squeezed Packet processing is enclosed with oversheath；The conductor uses the tinned copper wire of strands, and the synnema direction of the conductor twists direction again And adjacent interlayer is twisted to being twisted in the same direction；The shielded layer is woven using the tinned copper wire of electromagnetism interference；It is described to fill out 8~10 times for filling the stranding pitch diameter that a stranding pitch diameter is the insulated wire cores, and the two stranding mode and conductor strand direction are equal It is consistent；The separation layer using 0.02~0.05mm thickness polyester belt twin stack it is wrapped form, and overlap rate 15%~ Between 30%；The shielded layer uses tinned copper wire braid shielded structure, and braided wires diameter is 0.1~0.15mm, count 80%~88% and angle of weave between 40 °~70 °.

As a further improvement of the utility model, the packing using aramid fiber yarn or dacron thread or the rope made of hemp one kind or A variety of is core, and extrudes thermoplastic elastomer (TPE) and be made.

As a further improvement of the utility model, the synnema of the conductor and again twist pitch no more than described in 12 times The diameter dimension of conductor.

The insulating layer is made of cross-linking radiation thermoplastic elastomer (s) as a further improvement of the utility model,.

The oversheath uses thermoplastic elastic material system resistant to high temperature as a further improvement of the utility model, At.

Due to the application of the above technical scheme, the advantageous effects that the utility model has: the conductor of the technical program Synnema direction, twist again direction and adjacent interlayer twist to be it is consistent identical, the outer diameter of the conductor relative to traditional structure wants small, more Add soft tension, while improving the flexibility, resistance to bend(ing), shock resistance pulling force characteristic of cable；The shielded layer of the technical program It is woven using tinned copper wire, by control braided wires diameter and angle of weave, can effectively ensure that the resistance to bend(ing) energy of cable； The technical program also simultaneously by control count, can meet the shield effectiveness of cable；The technical program is by using irradiation Crosslinked thermoplastic elastomer has many advantages, such as low smoke and zero halogen, tension, wear-resisting, high temperature resistant, in effective protection as insulation and sheath While inside cable, the high temperature resistance of cable is improved.
