Abstract
The invention discloses a multicore coaxial self-temperature-controlling heating cable resistant to high temperature. The multicore coaxial self-temperature-controlling heating cable is composed of coaxial cable cores, a wrapping tape layer, a galvanized aluminum alloy wire shielding layer, a heat insulation layer, a high-temperature-resistant layer and a rubber protection jacket. The center of the wrapping tape layer wraps a piece of filler. The four coaxial cable cores are arranged in the mode that every two coaxial cable cores are closely arranged with the filler as the center in an externally-tangent mode. The high-temperature-resistant layer is made of foaming polyethylene comprising glass fibers and graphite. The cable is good in conductivity, resistance to high temperature and fatigue resistance, is mainly applied to the fields of electricity generation, metallurgy, computers, chemical engineering petroleum and the like, is excellent in anti-interference, can increase the utilization ratio of dissipated heat of the cable, and has remarkable energy conservation effect.
Description
Technical field
The invention belongs to field of cables, relate in particular to a kind of high temperature resistant multi-core coaxial self controlled heating cable.
Background technology
At present, along with Chinese society expanding economy, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the fields such as generating, metallurgy, computer, chemical petroleum, the aspects such as high and low temperature resistance to cable, fatigue durability, anti-broken string ability, heat dissipation, energy conservation, antijamming capability require all high especially.Only meet the requirements, could the better production and application that ensures cable.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide that a kind of resistance to elevated temperatures is good, fatigue durability is good, anti-broken string ability is strong, anti-interference and the high high temperature resistant multi-core coaxial self controlled heating cable of heat dissipation, energy conservation.
The present invention takes following technical scheme to realize: a kind of high temperature resistant multi-core coaxial self controlled heating cable, it is made up of coaxial core, belting layer, zinc-aluminium-alloy silk screen, thermal insulation layer, high-temperature-resistant layer and rubber sheath, described belting layer center is enclosed with a filler, described coaxial core is circumscribed four coaxial cores of closely arranging between two centered by described filler, and described high-temperature-resistant layer is to be made up of the polyethylene foamed that adds glass fibre, graphite.
Described coaxial core is made up of the inner wire wrapping up successively, interior skinning cortex, bare copper wire outer conductor, and described inner wire is some bursts of right stranded the forming of silver-plated annealed steel alignment.
The present invention has following beneficial effect in sum: this kind of cable conduction performance is good, resistance to elevated temperatures is good, fatigue durability is good, be mainly used in such as fields such as generating, metallurgy, computer, chemical petroleums, anti-interference is excellent, simultaneously, can make cable carry out directed distribute heat, heat orientation cable being produced passes to heated equipment, reduce heat loss, improve the utilance of cable distribute heat, and then reduced the loss to electric energy, play significant energy-conserving action.
