Abstract
The utility model discloses a kind of insulated aerial cable, 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；Gap portion between described cable core and non-woven fabrics belting layer is provided with packed layer.This utility model simple in construction, being arranged on of strengthening core is greatly increased the tensile characteristics of cable while not increasing cable volume, reducing the quantity of aerial cable support tower, the heating braid simultaneously arranged accelerates the melting rate of accumulated snow around cable, extends cable life.
Description
Technical field
This utility model relates to field of cables, particularly relates 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.
Utility model content
The purpose of this utility model 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, this utility model is achieved through 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 beneficial effects of the utility model are: this utility model simple in construction, reasonable in design, save the setting of cable support tower, have good tensile property, creep-resistant property and elongation percentage, simultaneously can accumulated snow around fast melt.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
The utility model is described in further detail for embodiment in below in conjunction with the accompanying drawings, but is not intended that any restriction of the present utility model.
Referring to shown in Fig. 1, this utility model 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 better embodiment of the present utility model, only it is used for convenient explanation this utility model, not this utility model is made any pro forma restriction, any art has usually intellectual, if in the range of without departing from the carried technical characteristic of this utility model, utilize the Equivalent embodiments that the done local of this utility model disclosed technology content is changed or modified, and without departing from technical characteristic content of the present utility model, all still fall within the range of this utility model technical characteristic.
