Description
Technical field
The present invention relates to field of cables, and in particular to a kind of aerial cable.
Background technique
The selection of the span of aerial insulated cable directly influences the project cost and operational safety of power transmission sequence, and engineering is made
The problem of valence and operational safety are currently in mutual restriction, though aerial insulated cable cable has been widely used, span length is short,
The problems such as safety is high, project cost just becomes increasingly conspicuous in the recent period, and power department is caused to be paid much attention to.
There has been aerial insulated cable national standard in the country, and fine aluminium core overhead insulated cable is only defined in the standard
Structure type and technical requirements, fine aluminium core overhead insulated cable much can not meet the laying requirement of large span, encounter rivers resistance
Every or when the case where being not easy short distance setting span points, there are also peripheral hardware steel strand wires to be wanted with the intensity for supporting cable for the cable laying
It asks, using the form, project cost will be significantly improved, and wire clamp and aerial insulated cable have certain friction, direct shadow
Ring the safe operation of the service life and route to cable.It will necessarily be replaced as it using reinforced large span aerial insulated cable
For product, reinforced large span aerial insulated cable can also increase span points in conventional project, reduce project cost.
Currently, most of managed using pvc, structure is single, since the anti-flammability of PVC material pipe is not good enough, easy point after being heated
Toxic gas is solved, and the coefficient of expansion is big, grazing is poor, and structure is easy to appear layering and damage, and service life is short, and effect is poor.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, provide it is a kind of there is good elasticity, anti-flammability,
Corrosion resistance, impact resistance aerial cable.
Technical solution: to achieve the above object, the present invention provides a kind of aerial cable, including communication cable pipe and setting
Overhead insulating core in communication cable pipe is constituted；The communication cable pipe, including pvc tube body, the tubular body are set
There are several silicone elastomer pipes, supporting layer, the pvc tube wall are filled between the silicone elastomer pipe and pvc tube body
Equipped with protective layer, the outer wall of the silicone elastomer pipe is equipped with several axially extending reinforcing ribs, and the inner wall of the pvc tube body is equipped with
Several axially extending limit ribs；The overhead insulating core is by aluminium alloy conductor, the crosslinking that is extruded in outside aluminium alloy conductor
Polyethylene layer and the foil woven cloth flame-retardant layer being woven in outside crosslinked polyetylene insulated layer；The overhead insulating core is set
It sets in silicone elastomer pipe.
Further, the foil woven cloth flame-retardant layer includes the aluminium foil layer set gradually from top to bottom, fire-retardant glue-line, resistance
Base fabric, fire-retardant glue-line and aluminium foil layer are fired, the aluminium foil layer uses the high-purity aluminium foil of 99% aluminium content, and fire-retardant glue-line uses
Polyurethanes composite glue added with calcium carbonate, flame retardant woven layer of cloth use low-pressure high-density polyethylene woven cloth, resistance
The upper and lower surfaces for firing base fabric are compound by polyurethanes composite glue and aluminium foil layer.
Further, the supporting layer and protective layer are constituted using carbon fibre material.
Compared with prior art, the beneficial effects of the present invention are:
Aluminium foil woven cloth flame-retardant layer is used in core, so that the shielding of cable is good, good flame retardation effect, anti-tensile and tearing
Intensity is good；Wherein, the high-purity aluminium foil of 99% aluminium content for this flame-retardant layer provides up to 97% reflectivity and lower than 3%
Emissivity；The use of aluminum foil material simultaneously provides certain plastic type for flame-retardant layer, and aluminium foil itself is completely fire-retardant, mentions
The flame retardant effect of flame-retardant layer is risen, polyurethanes composite glue of this materials'use added with calcium carbonate is multiple as bonding
It closes, it is more preferable compared to lamination and the compound fastness of other glue；Simultaneously as being added to fire retardant, flame retardant effect is fabulous, reaches not
The effect of combustion, flame retardant woven cloth can provide good flame retardant effect for flame-retardant layer, promote anti-tensile and tearing strength；In addition, adopting
Existing pvc pipe or oversheath are replaced with completely new communication cable pipe, sound construction is easy for installation, and tube body and single tube itself are adopted
With PVC, silicone elastomer material, there is good insulating properties and corrosion resistance, it is cheap；Pass through the supporting layer of carbon fibre material
And protective layer, solve that tubing impact resistance is poor, the low deficiency of anti-flammability also avoids that tubing breakage is caused to be asked by thermal expansion
Topic, extends the service life and using effect of tubing, to improve the insulating properties of cable, corrosion resistance, impact resistance, resistance
The performances such as combustion property.
