Abstract

The utility model discloses a tensile light cable used in mobile occasions, which is composed of main power line cores, insulated wire cores, a copper-clad steel armor layer and a ceramic polyurethane outer sheath, wherein each main power line core is formed by extruding a silicone rubber insulating layer on three conductive wire cores, and a ground wire core is arranged among the three conductive wire cores; each insulated wire core is formed by sequentially extruding a polyvinyl chloride sheath layer and a silver-plated copper conductor on high-strength tensile fiber cores from outside to inside; the two main power line cores and the two insulated wire cores are closely arranged in a spaced manner, and are extruded with a polytetrafluoroethylene insulating layer to form a cable core; and the cable core is sequentially extruded with the copper-clad steel armor layer and the ceramic polyurethane outer sheath from inside to outside. The tensile light cable has the advantages of large tensile resistance, shear resistance, bending resistance, high and low temperature resistance, light weight, small outer diameter, stable current and the like.

Description

A kind of moving field share tension lightweight cable

Technical field

The utility model relates to cable, relates in particular to a kind of moving field and share tension lightweight cable.

Background technology

Current normally used tension mobile cable, have that product external diameter is large, own wt is heavy, the shortcoming such as can not high-low temperature resistant weather-proof, the tensile cable that moving field share, particularly have out of doors under the unsettled occasion of certain span or cable high speed folding and unfolding occasion, cable is bearing very large stretching resistance and shearing force, is not in use easy to occur conductor thread core fracture through strengthening the cable of structural design; Cable insulation or restrictive coating are torn the breakage core that causes switching on and are short-circuited because frequent folding and unfolding causes; Cable for a long time out of doors instructions for use cable there is high and low temperature resistance and the performance such as weather-proof.In the time that cable is damaged, self weigh because the outside diameter of cable is large, change and lay inconvenience.It is little, lightweight that this just requires cable to have certain horizontal stretching resistance, anti-shearing, resistance to bending, high-low temperature resistant, external diameter of bearing, the advantages such as current stabilization.

Utility model content

For overcoming above-mentioned deficiency, the utility model object is to provide a kind of moving field and share tension lightweight cable.

Scheme of the present utility model is as follows: a kind of moving field share tension lightweight cable, it is made up of active force core, insulated wire cores, copper covered steel armour and ceramic polyurethane oversheath, described active force core is to extrude three conductor wire cores by silicone rubber insulation layer to form, and is provided with a ground wire core in the middle of three conductor wire cores; Described insulated wire cores ecto-entad extrudes high-strength tensile fibre core with pvc sheath and silver-plated copper conductor successively and forms; Two active force cores and two insulated wire cores interval close-packed arrays, extruded into cable core by teflon insulation layer; Described cable core is from inside to outside extruded with copper covered steel armour and ceramic polyurethane oversheath outward successively.

Described conductor wire core is to extrude two aluminium alloy conductors by polyvinyl chloride insulation layer to form.

The beneficial effects of the utility model: the utility model tension lightweight cable has large, anti-shearing, the resistance to bending of stretching resistance, high-low temperature resistant, weather-proof, lightweight, external diameter is little, the advantages such as current stabilization.

Brief description of the drawings

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

Wherein: 1, teflon insulation layer; 2, high-strength tensile fibre core; 3, silver-plated copper conductor; 4, pvc sheath; 5, copper covered steel armour; 6, ceramic polyurethane oversheath; 7, aluminium alloy conductor; 8, polyvinyl chloride insulation layer; 9, silicone rubber insulation layer; 10, wire core.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further;

As shown in Figure 1, a kind of moving field share tension lightweight cable, it is made up of active force core, insulated wire cores, copper covered steel armour 5 and ceramic polyurethane oversheath 6, described active force core is to extrude three conductor wire cores by silicone rubber insulation layer 9 to form, and is provided with a ground wire core 10 in the middle of three conductor wire cores; Described insulated wire cores ecto-entad extrudes high-strength tensile fibre core 2 with pvc sheath 4 and silver-plated copper conductor 3 successively and forms; Two active force cores and two insulated wire cores interval close-packed arrays, extruded into cable core by teflon insulation layer 1; Described cable core is from inside to outside extruded with copper covered steel armour 5 and ceramic polyurethane oversheath 6 outward successively.

Described conductor wire core is to extrude two aluminium alloy conductors 7 by polyvinyl chloride insulation layer 8 to form.

The rated voltage 3.6/6kV of this tension lightweight cable cable, belong to mobile electrical equipment cable for connecting, conductor is more soft, bending mobile better, and conductor has to bear and is not less than traction-resistant fibre nominal stretching resistance value, there is certain advantages such as horizontal stretching resistance, anti-shearing, resistance to bending, high-low temperature resistant, external diameter be little, lightweight of bearing.

Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and amendment; when its function producing does not exceed spiritual that specification contains yet, all should be within protection range of the present utility model.
