Abstract

The utility model discloses a flat cable with high tensile strength and high tearing resistance, and is characterized in that a jacket layer is extruded out of a cable core, a glass fiber belt is coiled out of the jacket layer, the outermost layer of the cable is a zinc-coated wire armoring layer, the cable core is formed by an insulation wire core and insulation reinforcements in parallel, the insulation wire core is located in the middle of the cable core, and the insulation reinforcements are located at both sides of the cable core; the insulation wire core comprises a conductor and an insulation layer extruded out of the conductor, the insulation reinforcements are spirally twisted by the conductor and a wire rope so as to form a wire core, and an insulation grid is coated out of the wire core. The flat cable, provided by the utility model, is a special flat cable for an iron ladle car, the cable has not only high tearing resistance, but a high-tensile structure, and the service life of the cable is improved.

Description

The high anti-tear flat cable of a kind of high tensile

Technical field:

The utility model relates to the high anti-tear flat cable of a kind of high tensile.

Background technology:

Hot-metal ladle and carriage has very high requirement because environment for use is abominable to its corresponding accessory cables.The hot-metal bottle vehicular cable drags repeatedly in use and is crooked, and external tensile force causes the oversheath of cable to damage easily, and operating ambient temperature is high simultaneously, and the temperature tolerance of cable is had very high requirement.High anti-tear flat cable at present commonly used adopts the braided steel wire armouring to protect oversheath, and the braiding armouring has very great help on anti-shearing force, but on longitudinal pulling force, ignores to some extent, causes common hot-metal bottle vehicular cable to be stretched in the vertical and is out of shape.The anti-tear flat cable of existing height generally adopts ordinary silicon rubber as insulation and sheath material, and its impart tear is lower, easily from the cable internal damage, has influenced the useful life of cable.

Summary of the invention:

For overcoming the defective of prior art, the purpose of the utility model is to provide a kind of high tensile high anti-tear flat cable, is the special-purpose flat cable of a kind of hot-metal ladle and carriage, and this cable not only has high anti-tear performance, also has tensile structure, improves the useful life of cable.

The utility model technical solution problem adopts following technical scheme:

The high anti-tear flat cable of a kind of high tensile; Cable conductor is extruded with restrictive coating outward; Outside said restrictive coating, be surrounded with glass fibre belt, the outermost layer of cable is the zinc-coated wire armour, and said cable core is arranged side by side with the insulation reinforcement by insulated wire cores and constituted; Said insulated wire cores is in the middle part of cable core, and said insulation reinforcement is in the both sides of cable core; Said insulated wire cores is made up of conductor and the insulating barrier that extrudes outside said conductor, and said insulation reinforcement constitutes core by conductor and steel wire rope spiral are stranded, outside said core, is surrounded with the insulation band.

Said insulating barrier and restrictive coating all adopt high anti-tear silicon rubber insulation.

Compared with present technology, the beneficial effect of the utility model is embodied in:

Through at the inner high tensile steel wire rope that adds of flat cable, not only can improve the tensile property of cable, can also reduce the influence of pulling force to cable conductor, avoid the excessive distortion that causes cable conductor of Yin Lali, thereby influence the performance and the useful life of cable.Adopt insulating barrier and the restrictive coating of high anti-tear silicon rubber insulation material simultaneously, improved the impart tear of cable insulation core, make that cable in use is not easy to tear, thereby improve the useful life of cable as cable.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Label among the figure: 1 zinc-coated wire armour, 2 glass fibre belts, 3 restrictive coatings, 4 insulation bands, 5 insulating barriers, 6 steel wire ropes, 7 conductors.

Below pass through embodiment, and combine accompanying drawing that the utility model is described further.

Embodiment:

Embodiment: combine Fig. 1; The high anti-tear flat cable of the high tensile of present embodiment is extruded with restrictive coating 3 outside cable conductor, outside restrictive coating 3, be surrounded with glass fibre belt 2; The outermost layer of cable is a zinc-coated wire armour 1; To be flat by insulated wire cores arrange with the insulation reinforcement cable core side by side constitutes, and insulated wire cores is in the middle part of cable core, and the insulation reinforcement is in the both sides of cable core; Insulated wire cores is made up of conductor 7 and the insulating barrier 5 that extrudes in conductor outside, and the insulation reinforcement constitutes core by conductor and steel wire rope 6 spirals are stranded, outside core, is surrounded with the band 4 that insulate.

In specifically being provided with, insulating barrier 5 all adopts high anti-tear silicon rubber insulation with restrictive coating 3.Conductor 7 is made up of the 6th type of copper conductor; The insulation reinforcement is formed with the conductor spiral is stranded by high tensile steel wire rope 6.
