Description

A kind of shielded cable of interlacing

Technical field

The utility model is related to electric power cable technical field, more particularly to a kind of shielded cable of interlacing.

Background technology

Cable, as the carrier for transmitting electric power and propagating information, serves huge effect in the development of the national economy, with The fast development of the quickening of urbanization process, electric power transmission and communication so that requirement more and more higher of the people to cable, at present The cable shield that cable enterprise generally takes mainly has two kinds, and one kind is conductors cross braid shielded, and another is conductor winding Shielding.

Conductors cross braid shielded：Because cable can be related to bending, torsion or mobile in use, conductors cross is compiled Shielding is knitted in bending, torsion or moving process because the tension force of conductor can cause the directly mutual stress of knitted conductor cross section Friction, shielded conductor fracture of wire can be caused by the accumulation that rubs, and extension fracture of wire over time can constantly increase, and is held Insulating barrier and outer quilt easily are punctured, short-circuit and pressure-resistant generation is caused, substantially reduces the service life and anti-jamming effectiveness of cable；

Conductor winding shielding：Because cable can be related to bending, torsion in use,

1) bend：Conductor winding shielding in BENDING PROCESS shielded conductor due to tension force can cause bending Outboard Sections lead Body is moved, and makes the internal object shielded exposed, reduces the service life and anti-jamming effectiveness of cable；

2) reverse：Conductor winding shielding is in twist process, if shielded conductor torsional direction and winding side in stress To consistent, shielded conductor is completely in stress, if torsional direction and winding direction on the contrary, if shielded conductor it is completely loose Relax, and be not easy to return to initial state, easily cause winding shielded conductor and gather, reduction shielding density, case above Easily make shielded conductor fatigue and fracture, easily puncture insulating barrier and outer quilt, cause short-circuit and pressure-resistant generation, and reduce electricity The service life and anti-jamming effectiveness of cable.

Utility model content

To overcome disadvantages mentioned above, the purpose of this utility model is to provide a kind of shielded cable of interlacing, can prevented Shielding braid conductor fractures, worn and torn, and reduction shielded conductor punctures the risk of insulation and outer quilt, reduces pressure-resistant short-circuit generation, carries High shield effectiveness and cable service life.

In order to reach object above, the technical solution adopted in the utility model is：A kind of shielded cable of interlacing, bag Include and insulating barrier is coated with outside some conductors, every conductor, the conductor strand of some coated insulation layers constitutes cable core, described Cable core is coated with woven shield, and the woven shield is coated with oversheath, and the woven shield is by high strength fiber Dimension silk and shielded conductor, which are cross-woven, to be formed, and the tensile strength for making whole cable by high strength fibre silk is improved.

Further, described lead is provided with packed layer between woven shield and the cable core.

Further, increase winds electroconductive nylon band/aluminium foil of one layer of 100% coverage rate on the inside of the woven shield, More preferable shield effectiveness can be reached and friction of the shielded conductor to cored wire is reduced.

Further, the high strength fibre silk is aramid fiber silk.

Further, the shielded conductor is copper wire.

Further, crossed is wound between the high strength fibre silk and the shielded conductor, does not influence conductor Electric conductivity, improve shield effectiveness, the equidirectional coverage rate of conductor can adjust arbitrarily.

Further, the oversheath is thermoplasticity/thermoset elastomeric material.

A kind of cable for interlacing that the utility model is provided, makes shape between shielded conductor and inner side insulation and oversheath Into buffering, and every beam conductor of shielded conductor is separated, significantly improve cable and cause shielding in torsion and BENDING PROCESS Conductor fracture of wire, it is to avoid puncture insulation and oversheath, causes short-circuit and pressure-resistant generation, improves the service life of cable and anti-interference Effect, shielding coverage rate is easily adjusted, and can reach 100% covering, makes the tension of whole cable strong by high strength fibre silk Degree is improved.

Embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite Define.

Referring to shown in accompanying drawing 1, Fig. 2, a kind of shielded cable of interlacing in the present embodiment, including some conductors 1, Every conductor 1 is outer to be coated with insulating barrier 2, the stranded composition cable core of conductor 1 of some coated insulation layers 2, the cable core outsourcing Woven shield 4 is covered with, the woven shield 4 is coated with oversheath 5, and the woven shield 4 is by high strength fibre silk 41 and shielded conductor 42 be cross-woven and form, the tensile strength for making whole cable by high strength fibre silk 41 is improved.

Described lead is provided with packed layer 6 between woven shield 4 and the cable core.

Electroconductive nylon/aluminium foil strip 3 of the inner side of woven shield 4 increase by one layer of 100% coverage rate of winding, can reach The friction of more preferable shield effectiveness and reduction shielded conductor 42 to cored wire.

The high strength fibre silk 41 is aramid fiber silk.

The shielded conductor 42 is copper wire.

Crossed is wound between the high strength fibre silk 41 and the shielded conductor 42, and leading for conductor 1 is not influenceed Electrically, shield effectiveness is improved, the equidirectional coverage rate of the conductor 1 can be adjusted arbitrarily.

The oversheath 5 is thermosetting/thermoplastic elastomer (s).

Embodiment of above is only to illustrate technical concepts and features of the present utility model, and its object is to allow be familiar with this skill The people of art understands content of the present utility model and is carried out, and protection domain of the present utility model, all can not be limited with this The equivalent change or modification done according to the utility model Spirit Essence, should all cover in protection domain of the present utility model.
