Description
Technical field
It the utility model is related 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 of power transmission sequence and safe for operation, and engineering is made
Valency and the problem of being currently in mutual restriction safe for operation, though aerial insulated cable cable has been widely used, span length is short,
The problems such as security is not high, construction costs just becomes increasingly conspicuous in the recent period, and causes 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, fine aluminium core overhead insulated cable much can not meet the laying requirement of large span, run into rivers resistance
Every or be not easy short distance set span points situation when, the cable laying also have peripheral hardware steel strand wires with support the intensity of cable will
Ask, using the form, construction costs will significantly improve, and wire clamp and aerial insulated cable have certain friction, direct shadow
Ring the safe operation of the service life and circuit to cable.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, because thickness of insulating layer is limited, and various additives are being placed with Insulation Material, so as to 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, it is badly in need of aerial cable of the exploitation with the performance such as high abrasion, corrosion resistance, 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.
Utility model content
Purpose of utility model：In order to overcome the deficiencies in the prior art, there is provided it is a kind of simple in construction, flexible,
Changeability, environment-friendly cold weather-proofing aerial insulation cable.
Technical scheme：To achieve the above object, the utility model provides a kind of cold-resistant weather-proofing aerial insulation cables of 1kV,
Including four insulated wire cores, connected from each other by arc elastic connection strengthening rib two-by-two between described four insulated wire cores
Connect；Heat-conducting block is provided with the gap that four insulated wire cores and four arc elastic connection strengthening ribs are inwardly formed, in heat conduction
The center of block 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 coated in insulating barrier outside epoxy weather resistant coatings form.
Further, described epoxy weather resistant coatings are by hydrogenated bisphenol A epoxy resin and modified fatty amine curing agent
Base-material is prepared.
Compared with prior art, the beneficial effects of the utility model are：
1st, arc elastic connection strengthening rib instead of dowel of the prior art, change original non-stretchable ask
Topic so that cable is flexible, has retractility when being squeezed；Also become more flexibly, to give in an installation in addition
Installation is brought conveniently.
2nd, not added in the weather-proof insulating materials of environment-friendly type influences the additive of its performance, ensures 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 heat is continuously produced, core insulating barrier and sheath is kept certain temperature,
So that cable occurs without phenomena such as hardening, embrittlement, cracking, still can free bend, the mobile use longevity for using, improving 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.
