Description
Technical field
The present invention relates to field of cables, and in particular to a kind of multicore high temperature photoelectric composite silicone rubber jacketed cable.
Background technology
With the development of society, the demand of cable is increasing, the field being related to is more and more wider, the electricity in some fields
If cable needs cable to possess extraordinary resistance to elevated temperatures, especially heat dispersion, cable conductor on is chronically at height
Among warm environment, situations such as damage occurs in conductor, so as to cause the electric property of cable, signal transmission performance etc. by very big
Influence, it is impossible to continue to meet use requirement.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, there is provided one kind is simple in construction, easy to use, heat-insulated
Performance is good, the multicore high temperature photoelectric composite silicone rubber jacketed cable of perfect heat-dissipating.
Technical scheme：To achieve the above object, the present invention provides a kind of multicore high temperature photoelectric composite silicone rubber sheath electricity
Cable, including cable core, described cable core fill silicon by gap of many insulated wire cores after stranded again between three insulated wire cores
Sour aluminium ceramic fiber layer；Thermal insulation layer, secondary shielding layer, aluminium alloy armored layer, heat-sink shell and silicon rubber are sequentially provided with outside cable core
Plastic boot layer, described silicone rubber jacket layer outer surface coating high-temperature resistant coating layer；It is symmetrical provided with one group in described screen layer
Fiber unit；Described heat-sink shell is provided with a heat emission hole stretched out through silicone rubber jacket layer.
Further, described insulated wire cores are extruded in insulating barrier outside aluminium alloy conductor, by aluminium alloy conductor, successively
One screen layer and inner sheath are constituted.
Further, described fiber unit is made up of optical fiber and the protecting pipe being extruded in outside optical fiber.
Further, the thermal insulation layer is nanometer micropore insulation material layer.
Further, the heat-sink shell is polystyrene foam plastics layer.
Further, the composite that described heat emission hole is composited by carbon fiber and copper is constituted.
Compared with prior art, the beneficial effects of the present invention are：
1st, the gap filling alumina-silicate ceramic fibre layer and the thermal insulation layer being provided between three insulated wire cores so that cable
Unit weight is light, high temperature resistant, heat endurance are good, pyroconductivity is low, thermal capacitance is small, resistance to mechanical is vibrated, expanded by heating is small, heat-proof quality
It is good, by the extraneous heat barrier of cable outside so that the insulated wire cores service life in cable core is longer, can make at high temperature
Industry.
2nd, provided with polystyrene foam plastics layer, with heat absorption function, the heat absorption in cable is come, and by dissipating
Hot hole discharges heat outside cable so that will not be because heat is too high and influences the stable work of cable in cable.
3rd, high-temperature resistant coating layer and thermal insulation layer can balance out the outside heat entered in cable conductor successively, so that
Possesses good temperature environment inside cable core, so as to more optimize the temperature in use environment of conductor so that cable possesses very well
Resistance to elevated temperatures, it is ensured that conductor is capable of the use of normal continuous in higher external temperature environment, the use effect of cable
Fruit has obtained effective guarantee, and extends the service life of cable.
4th, oversheath uses silicon rubber oversheath, and silicon rubber has much better heat resistance than General Purpose Rubber, can be at 150 degree
Under almost forever using and without performance change, can continuously be used 10000 hours under 200 degree, one section also can be used under 350 degree
Time so that the heat resistance of cable is higher than common rubber cable several times.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
