Description
Technical field
The present invention relates to field of cables, and in particular to a kind of 1kV resists cold weather-proofing aerial insulation cable.
Background technology
The selection of the span of aerial insulated cable directly influences the construction costs and operation safety of power transmission sequence, and engineering is made
Valency and operation safety are the problem of be currently in mutual restriction, though aerial insulated cable cable has been widely used, span length is short,
Security is not high, construction costs the problems such as just become increasingly conspicuous in the recent period, and cause power department to be paid much attention to.
There has been aerial insulated cable national standard the country, and simply fine aluminium core overhead insulated cable is defined in the standard
Structure type and technical requirements, what fine aluminium core overhead insulated cable much can not meet large span lays requirement, runs into rivers resistance
Every or be difficult short distance set span points situation when, the cable laying also have peripheral hardware steel strand wires with support cable intensity will
Ask, using the form, construction costs will be significantly improved, and wire clamp and aerial insulated cable have certain friction, direct shadow
Ring the service life to cable and the safe operation of circuit.It will necessarily be replaced using reinforced large span aerial insulated cable as it
For product, reinforced large span aerial insulated cable can also increase span points in conventional project, reduce construction costs.
Existing aerial insulated cable is common aerial cable, and one layer of black insulation is only coated with the outside of cored wire conductor
Layer.The process kind of above-mentioned cable is being manufactured, various additives are being placed with because thickness of insulating layer is limited, and in Insulation Material, so that shadow
The various performances of cable insulation are rung.The aerial cable applications of said structure are in increasingly tall and big and various local or special of trees
Its regional wearability, the corrosion-resistant of weather, it is short not only result in service life, and danger coefficient is high.With modernization city
The development in city, being badly in need of developing has high abrasion, corrosion resistance, the aerial cable of the performance such as service life length.
Currently, most cables is only applicable in the narrow normal temperature ring of a temperature range, in extremely frigid zones, these electricity
The severe safety problem such as hardening, cracking, embrittlement occurs in cable, will no longer be suitable in psychro-environment, this is for extremely frigid zones
Supply of electric power will be a very big problem.
At present, the dowel of aerial cable is all to only serve connection function so that the structure of cable is fixed, without bullet
Property, it is impossible to it is flexible, it is harder, be squeezed will easily be compressed it is bad so that the service life of cable is short, and cost is high.
The content of the invention
Goal of the invention：It is variable in order to overcome the deficiencies in the prior art there is provided one kind is simple in construction, flexible
Property, environment-friendly cold weather-proofing aerial insulation cable.
Technical scheme：To achieve the above object, the present invention provides a kind of cold-resistant weather-proofing aerial insulation cables of 1kV, including
Connected from each other by arc elastic connection strengthening rib two-by-two between four insulated wire cores, four described insulated wire cores；
The gap that four insulated wire cores and four arc elastic connection strengthening ribs are inwardly constituted is provided with heat-conducting block, in heat-conducting block
The heart is provided with heating tape, and heating tape is provided with the power hole being connected with power supply.
Further, described insulated wire cores are by aluminium alloy conductor, the environment-friendlyweather-proof weather-proof material being coated on aluminium alloy conductor
The insulating barrier of composition and the epoxy weather resistant coatings being coated in outside insulating barrier are constituted.
Further, described epoxy weather resistant coatings are by hydrogenated bisphenol A epoxy resin and modified fatty amine curing agent
Base-material is prepared from.
Compared with prior art, the beneficial effects of the present invention are：
1st, arc elastic connection strengthening rib instead of dowel of the prior art, the problem of changing original non-stretchable,
So that cable is flexible, there is retractility when being squeezed；Also become in an installation in addition more flexibly, to installation
Bring conveniently.
2nd, in the weather-proof insulating materials of environment-friendly type without influence its performance additive, it is ensured that insulating properties；Add frame
The wearability of empty cable, in weather Special section, weather resistant insulation can protect cable continuously to work, without interruption.
3rd, heating tape being added in cable to be powered, then insulated wire cores being conducted to by heat-conducting block, cable is out of doors in use, only
Heating tape is accessed into power supply, it is possible to continuously produce heat, core insulating barrier and sheath is kept certain temperature,
So that cable occurs without the phenomenons such as hardening, embrittlement, cracking, still can free bend, movement use, improve the use longevity of cable
Life so that cable, because icing causes communication signal transmissions to interrupt, causes the economic loss that can not be saved in ice and snow weather.
4th, described epoxy weather resistant coatings are prepared by hydrogenated bisphenol A epoxy resin and modified fatty amine curing agent for base-material
Form so that cable has that weather resistance, medium-resistance are excellent, can be widely applied to wind-power electricity generation, ship, offshore oil are put down
The fields such as platform, highway, high-speed railway aerial cable.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
