Description
Technical field
It the utility model is related to field of cables, and in particular to a kind of novel computer cold resistant cable.
Background technology
At present, a kind of communication cable of the computer cable as transmission signal, it is made that for the development of Communication in China cause
Remarkable contribution.With industrial expansion, the overlay area of signal of communication is more and more wider, common tensile type armature of cable layer
It is the pattern using steel wire winding, so adds the total weight of cable.The communication cable laying of some big scale lengths is in having
In the larger environment of height fall, often it is damaged or even breaks because cable is conducted oneself with dignity, particularly rain jelly, ice and snow weather etc.
The influence of harsh weather, communication cable are possible to because icing causes communication signal transmissions to interrupt, and cause the economic damage that can not be saved
Lose.
Utility model content
Purpose of utility model：In order to overcome the deficiencies in the prior art, there is provided one kind has high intensity, high tenacity resistance to
Burn into high temperature resistant, insulaion resistance height, good flame resistance, light weight, long lifespan, on-deformable novel computer cold resistant cable.
Technical scheme：To achieve the above object, the utility model provides a kind of novel computer cold resistant cable, including cable
Core, described cable core are twisted by four pair twist insulated wire cores；Described pair twist insulated wire cores are by a pair twist at its center
Close wire and wrapped pair twist twining package tape and split-phase proof copper-wire braided screen layer outside stranded conductor is formed successively；The space of cable core
Place's extruding heating tape, the wrapped rock wool heat-preservation layer outside cable core, extrudes rubber and plastic rubber inner sheath, in rubber and plastic rubber outside rock wool heat-preservation layer
The outer braided steel wire layer of glue inner sheath, extrudes carbon screw thread oversheath outside steel wire floor.
Further, described stranded conductor is made up of conductor and the inorganic mineral insulation layer being extruded in outside conductor.
Further, described heating tape external power supply.
Compared with prior art, the beneficial effects of the utility model are：
1st, described heating tape external power supply, it is possible to continuously produce heat, make the insulating barrier and sheath of cable
Keep certain temperature so that cable occurs without phenomena such as hardening, embrittlement, cracking, still can free bend, it is mobile use, carry
The high service life of cable, plus rock wool heat-preservation layer, can cause the temperature after heating to be not easy to dissipate.
2nd, 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, there is excellent low temperature resistant, wear-resisting, UV radiation, the resistance to characteristic such as circumnutate.
3rd, rubber and plastic rubber inner sheath is to close bubble structure, and the water in outside air is difficult to penetrate among material, is had excellent
Different water vapor penetrating power, cold insulation heat-insulation layer appearance need not add vapor barrier layer again.The dampness factor mu value of rubber and plastic is more than 3500
（ISO9346）Built-in anti-steam layer is formed, even if product scratches and nor affects on overall every vapour, there is remarkable resistance to day
Wait, be anti-aging, anti-severe cold, anti-inflammatory heat, resist drying, moisture resistant, also with uvioresistant, resistance to ozone, not aging in 25 years, no
The characteristics such as deformation, non-maintaining service life.
4th, oversheath uses carbon screw thread oversheath, have high intensity, high tenacity corrosion resistant, high temperature resistant, insulaion resistance it is high,
Good flame resistance, light weight, long lifespan, a variety of advantages such as it is unlikely to deform；Moulding is in special thread shape, can bend bypassing freely
Barrier, convenient construction；To reduce connector, quick construction can be made, it is easy to maintenance；Shape of threads physics moulding, makes its pressure resistance
Degree is big, will not be deformed in underground because of weight, and acidproof, salt, alkalescence can be splendid, and service life was up to more than 50 years, extensive use
In city street lamp circuit ground covering project, electric railway electric power, the laying ground covering project of communication cable, highway electric power, lead to
Believe the project for construction and upgrading of facility, construction of residential quarters engineering and the underground cable engineering of park and large-scale public place of entertainment, be
Optimal underground cable sheath tubing.
