Description
Technical field
The utility model is related to field of cables, and in particular to a kind of rubber plastics-insulated movement cold-resistant flexible cable.
Background technology
As the footprint that the mankind explore is all over the world, each corner in the world has also been stretched in the application of electric power, natural
It can't do without setting foot in the high and cold area of low temperature.Currently, most cables is only applicable in the narrow normal temperature ring of a temperature range,
In extremely frigid zones, the severe safety problem such as hardening, cracking, embrittlement occurs in these cables, will no longer be suitable in psychro-environment,
This will be a very big problem for the supply of electric power of extremely frigid zones.
Utility model content
Goal of the invention：In order to overcome the deficiencies in the prior art rubber plastics-insulated mobile with the soft electricity that resists cold there is provided one kind
Cable.
Technical scheme：To achieve the above object, the utility model provides a kind of rubber plastics-insulated movement cold-resistant flexible cable, bag
Include cable core, described cable core by many rubber plastics-insulated cores and with the same number of heating tape of rubber plastics-insulated core it is stranded and
Into；Heat preservation rock is filled in the gap of cable core, being wrapped with wheat in cable core draws, and second is extruded outside wheat is drawn cold-resistant rubber plastics-insulated
Layer, the wrapped metal screen layer outside the second cold-resistant rubber plastics-insulated layer, the wrapped heating tape outside metal screen layer is squeezed outside heating tape
Bag inner sheath, finally extrudes polyurethane thermal pipe outside inner sheath.
Further, described rubber plastics-insulated core is three, by aluminium alloy conductor, be extruded in outside aluminium alloy conductor the
One cold-resistant rubber plastics-insulated layer and the wrapped polyurethane heat-insulation band outside the first cold-resistant rubber plastics-insulated layer are constituted.
Further, described heating tape external power supply.
Further, described the first cold-resistant rubber plastics-insulated layer and second resists cold rubber plastics-insulated layer for rubber-covered, poly- second
Alkene insulation, polyvinyl chloride insulation, crosslinked polyetylene insulated and cold-resistant butyronitrile polymer insulation one kind therein.
Further, the inner sheath is cold-resistant butyronitrile polymer jacket.
Compared with prior art, the beneficial effects of the utility model are：
1st, heating tape and together twisted synthesizing cable are added in cable, composition heat tracing type is combined cable core, companion also is provided with outside cable
The torrid zone, as long as cable by heating tape out of doors in use, access power supply, it is possible to continuously produce heat, make cable
Insulating barrier and sheath keep certain temperature so that cable occurs without the phenomenons such as hardening, embrittlement, cracking, still can free bend,
Movement is used, and improves the service life of cable.
2nd, cable core gap filling heat preservation rock so that the internal insulation effect of cable is more preferable.
3rd, wheat is coated after stranding to draw, the soft rock wool of central filler, make the overall more substantial, rounding of cable.
4th, the rubber plastics-insulated layer that resists cold is used inside and outside cable so that the cold tolerance of cable improves a step again.
5th, polyurethane thermal pipe is provided with using polyurethane heat-insulation band and cable outermost layer in core, inside and outside dual is protected
The cold resistance of cable so that there is cable intensity height, impact resistance, the prestressing force of resistance to environmental aging to split, corrosion-resistant, low temperature resistant, easy
Welding, easy construction, strictly seal ne-leakage, also with unit weight is light, intensity is high, adiabatic, sound insulation, fire-retardant, cold-resistant, anti-corrosion, no
The excellent characteristics such as water suction, simple and quick construction, in addition, polyurethane heat insulation material, adaptive temperature is+120 DEG C--196 DEG C 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.
6th, polyurethane thermal pipe causes cable in laying is installed also than original convenience so that cable laying efficiency is significantly
Improve.
7th, this cold resistant cable can be used for cold area in north, can be widely used in electric power, machine-building, automobile and other industries
On, with excellent low temperature resistant, wear-resisting, UV radiation, the resistance to characteristic such as circumnutate.
