Abstract

The invention discloses an insulated overhead cable. The insulated overhead cable comprises a cable core and five sheath layers coating the cable core. The five sheath layers are the non-woven fabric wrapping tape layer, the crosslinking semiconductor shielding layer, the heating woven layer, the electrical isolation layer and a weather-proof crosslinking polyethylene insulated sheath layer in sequence from interior to exterior. The cable core comprises a cable core body and a reinforcing core. The cable core body comprises a conductor and a metal shielding layer, a liner layer, a waterproof layer and a polyester rubber insulated layer which sequentially coat the conductor. The reinforcing core is composed of a plurality of twisted high-strength bearing steel cores. A filling layer is arranged at an interval between the cable core and the non-woven fabric wrapping tape layer. The insulated overhead cable is simple in structure; due to the arrangement of the reinforcing core, the tensile property of the cable is greatly improved while the size of the cable is not increased, and the number of overhead cable supporting towers is reduced; meanwhile, due to the arrangement of the heating woven layer, the melting rate of snow accumulated on the periphery of the cable is increased, and the service life of the cable is prolonged.

Description

A kind of insulated aerial cable
Technical field
The present invention relates to field of cables, particularly relate to a kind of insulated aerial cable.
Background technology
Aerial cable is used for the long distance delivery of electric power, it is often necessary to crosses over mountain after mountain, use support tower aerial cable, and cable requires tension for the construction of cable, keeps away water, weather-proof etc. simultaneously;Cable has the aspects such as tensile property, creep-resistant property and elongation percentage also to have high requirement, existing aerial cable difference to meet for conductor simultaneously.
Summary of the invention
The purpose of the present invention be that provide to solve the problems referred to above a kind of simple in construction, pull resistance good, reduce support tower arrange, the insulated aerial cable of fast melt accumulated snow.
To achieve these goals, the present invention is achieved by the following technical solutions: a kind of insulated aerial cable, and it includes cable core and five layers of restrictive coating of the outside cladding of cable core;Five layers of described restrictive coating are followed successively by non-woven fabrics belting layer, cross-linked semiconductor screen layer, heating braid, electricity isolated layer and weather-proof crosslinked polyetylene insulated sheath from inside to outside;Described cable core includes cable core and strengthening core;Described cable core includes metal screen layer, inner liner, waterproof layer and the lactoprene insulating barrier being coated with successively outside conductor and conductor;Described strengthening core is made up of many mutually stranded high intensity carrying steel cores;The described cable core of many groups constitutes cable core around the uniform star quad stranding of strengthening core;Gap portion between described cable core and non-woven fabrics belting layer is provided with PP gasket for packing.
Further,Described conductor is rare earth aluminum alloy conductor.
Further, described heating braid is formed by carbon fiber braiding.
Further, described waterproof layer is made up of steel pipe outside coating epoxy resin layer.
The invention has the beneficial effects as follows: present configuration is simple, reasonable in design, save the setting of cable support tower, have good tensile property, creep-resistant property and elongation percentage, simultaneously accumulated snow around energy fast melt.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
The present invention is described in further detail for embodiment in below in conjunction with the accompanying drawings, but is not intended that any limitation of the invention.
Referring to shown in Fig. 1, the present invention provides a kind of technical scheme one insulated aerial cable, and it includes cable core and five layers of restrictive coating of the outside cladding of cable core;Five layers of restrictive coating are followed successively by non-woven fabrics belting layer 1, cross-linked semiconductor screen layer 2, heating braid 3, electricity isolated layer 4 and weather-proof crosslinked polyetylene insulated sheath 5 from inside to outside;Heating braid 3 is woven by carbon fiber and forms, and the heat produced by heating braid 3 melts the ice and snow that cable outer surface is piled up, and improves the use quality of cable product in the case of cable weight increases seldom.
Cable core includes cable core 6 and strengthening core 7;Cable core 6 includes metal screen layer 9, inner liner 10, waterproof layer 11 and the lactoprene insulating barrier 12 being coated with successively outside conductor 8 and conductor;Conductor 8 is rare earth aluminum alloy conductor, and waterproof layer 11 is made up of steel pipe outside coating epoxy resin layer, and rare earth aluminum alloy conductor 8 relatively conventional aluminium conductor or copper conductor have preferable tensile property, creep-resistant property and elongation percentage;The design of epoxy resin layer waterproof layer 11 improves the water resistance of cable, extends the service life of cable.
Strengthening core 7 is made up of many mutually stranded high intensity carrying steel cores;Many group cable cores 6 constitute cable core around the uniform star quad stranding of strengthening core 7;Gap portion between cable core and non-woven fabrics belting layer 1 is provided with PP gasket for packing.
Embodiment provided above is the better embodiment of the present invention, only it is used for the convenient explanation present invention, not the present invention is made any pro forma restriction, any art has usually intellectual, if in the range of without departing from the carried technical characteristic of the present invention, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and without departing from the technical characteristic content of the present invention, all still fall within the range of the technology of the present invention feature.
