Description
Technical field
The present invention relates to field of cables, and in particular to a kind of aerial cable.
Background technology
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 only fine aluminium core overhead insulated cable is defined in the standard
Structure type and technology requirement, fine aluminium core overhead insulated cable much can not meet the laying requirement of large span, encounter rivers resistance
Every or be not easy short distance be arranged span points the case where when, which also has peripheral hardware steel strand wires to be wanted with the intensity for supporting cable
It asks, using the form, project cost will significantly improve, and wire clamp and aerial insulated cable have certain friction, direct shadow
Ring the safe operation to the service life and circuit of 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 susceptible to layering and damage, and service life is short, and effect is poor.
Invention content
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 bodies, the tubular body are set
There are several silicone elastomer pipes, supporting layer, the pvc tube walls are filled between the silicone elastomer pipe and pvc tube bodies
Equipped with protective layer, the outer wall of the single tube is equipped with several axially extending reinforcing ribs, and the inner wall of the pvc tube bodies is equipped with several
Axially extending limit rib；The overhead insulating core is by aluminium alloy conductor, the crosslinked polyethylene that is extruded in outside aluminium alloy conductor
Insulating layer and the foil woven cloth flame-retardant layer being woven in outside crosslinked polyetylene insulated layer；The overhead insulating core is arranged in silicon
In glue elasticity 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, fire-retardant glue-line to use
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 surface for firing base fabric is 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 strength
It is good；Wherein, the reflectivity and transmitting less than 3% that the high-purity aluminium foil of 99% aluminium content provides up to 97% for this flame-retardant layer
Rate；The use of aluminum foil material simultaneously provides certain plastic type for flame-retardant layer, and aluminium foil itself is completely fire-retardant, improves
The flame retardant effect of flame-retardant layer, polyurethanes composite glue of this materials'use added with calcium carbonate is as compound, the phase of bonding
It is more preferable compared with lamination and the compound fastness of other glue；Simultaneously as being added to fire retardant, flame retardant effect is fabulous, reaches non-ignitable effect
Fruit, flame retardant woven cloth can provide good flame retardant effect for flame-retardant layer, promote anti-tensile and tearing strength；In addition, using completely new
Communication cable pipe replace existing pvc manage or oversheath, sound construction is easy for installation, tube body and single tube itself using PVC,
Silicone elastomer material has good insulating properties and corrosion resistance, cheap；Supporting layer by carbon fibre material and protection
Layer, solves that tubing impact resistance is poor, and the low deficiency of anti-flammability, the problem for also avoiding being led to tubing breakage by thermal expansion is prolonged
The service life and using effect for having grown tubing, to improve insulating properties, corrosion resistance, impact resistance, the anti-flammability of cable
Etc. performances.
