Description

A kind of colliery stretch-proof insulated cable

Technical field

This utility model is related to field of cables, more particularly, to a kind of colliery stretch-proof insulated cable.

Background technology

At present, with scientific and technical development, also in rapid advances, bring therewith is electricity in the field such as industry and coal mining The increase of cable consumption, has higher requirement in colliery field to cable, because cable generally requires it is entered in use Row pulls and bending is it is easy to lead to cable to lead to cable body internal structure damaged, in its work because extraneous stress is excessive It is easy to break down, bring a lot of inconvenience to staff.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of stretch-proof of colliery to insulate Cable.

This utility model takes technical scheme below to realize：A kind of colliery stretch-proof insulated cable, it includes Cable body, described cable body includes conductor, enhancement layer, screen layer and oversheath, and described cable body is internally provided with many Individual enhancement layer；Described enhancement layer is internally provided with conductor；And described cable body inner hub location arranges a guide core；Institute State setting layer of metal braiding layer outside enhancement layer；Layer protective layer is closely extruded outside described wire sheathing；Outside described protective layer Extrude one layer of semiconductive lapping layer；One layer of screen layer is extruded outside described semiconductive lapping layer；One layer is extruded surely outside described screen layer Given layer；And extrude one layer of oversheath outside described stabilized zone.

A kind of above-mentioned colliery stretch-proof insulated cable, gap portion setting between described enhancement layer and wire sheathing One layer of stretch-resistant layer.

A kind of above-mentioned colliery stretch-proof insulated cable, described conductor is made using naked copper wire material.

A kind of above-mentioned colliery stretch-proof insulated cable, described guide core is formed using tinned copper wire braiding.

A kind of above-mentioned colliery stretch-proof insulated cable, described protective layer is made using Ceramic silicon rubber material.

A kind of above-mentioned colliery stretch-proof insulated cable, described stabilized zone is made using PE insulant.

A kind of above-mentioned colliery stretch-proof insulated cable, described oversheath is made using thermoplastic vulcanizate material.

This utility model has the advantages that in sum：This utility model has reasonable in design, stretch-proof Effect is good and the advantages of long service life, described oversheath is made using thermoplastic vulcanizate material, thus having preferably Elasticity and bend resistance effect, can effectively be solved cable and easily be ftractureed with ground friction and pullling back and forth in use etc. Problem, substantially prolongs the service life of cable body.

Brief description

Fig. 1 is this utility model cross-sectional structure schematic diagram；

Wherein：1st, cable body；2nd, conductor；3rd, enhancement layer；4th, stretch-resistant layer；5th, guide core；6th, wire sheathing；7th, protect Sheath；8th, semiconductive lapping layer；9th, screen layer；10th, stabilized zone；11st, oversheath.

Specific embodiment

As shown in figure 1, a kind of colliery stretch-proof insulated cable, it includes cable body 1, and described cable body 1 includes Conductor 2, enhancement layer 3, screen layer 9 and oversheath 11, described cable body 1 is internally provided with multiple enhancement layers 3；Described enhancement layer 3 are internally provided with conductor 2；And described cable body 1 inner hub location arranges a guide core 5；Described enhancement layer 3 is outer to be arranged Layer of metal braiding layer 6；Described wire sheathing 6 is outer closely to extrude layer protective layer 7；One and half are extruded outside described protective layer 7 Conductive lapping layer 8；One layer of screen layer 9 is extruded outside described semiconductive lapping layer 8；One layer of stabilized zone 10 is extruded outside described screen layer 9； And extrude one layer of oversheath 11 outside described stabilized zone 10.

Described conductor 2 is made using naked copper wire material, and described naked copper wire material not only makes conductor 2 conductivity high, Er Qiecai Matter is more soft, has preferable antioxygenic property；Described stretch-resistant layer 4 not only increases the tensile resistance of cable body 1, And make cable body 1 internal structure more compact；Described guide core 5 is formed using tinned copper wire braiding, can effectively shut out The interference that insulation magnetic wave causes to cable is so as to work process is more stable；Described wire sheathing 6 one aspect can play and add The effect of strong uniform electric field, another side can effectively strengthen the mechanical strength of cable body 1；Described protective layer 7 is using pottery SiClx elastomeric material is made, and not only has high temperature resistant and fire-retardant characteristic, and has preferable pliability, effectively enhances The practicality of cable body 1, extends the service life of cable；Described semiconductive lapping layer 8 can be used as earth lead, and cable is being sent out Life punctures or during earth fault, electric current can quickly introduce low it is ensured that the safety in colliery；Described screen layer 9 can reduce Electric current penetrates the interference that screen layer 9 causes, and reduces multiple reflections interference electromagnetic field, makes the frequency change of cable output or frequency ripple abnormal Become and reduce, reduce cable to outside interference；Described stabilized zone 10 is made up of PE material, have preferable chemical stability and Excellent dielectric properties, improve the dielectric properties of cable；Described oversheath 11 is made using thermoplastic vulcanizate material, from And there is preferably elasticity and bend resistance effect, can effectively solve cable in use with ground friction and pulling back Pull easy problems of crack, substantially prolongs the service life of cable body 1.

The above is this utility model embodiment, thus the construction described in all application range according to this utility model, feature and Equivalence changes or modification that principle is done, are all included in this utility model patent claim.
