Description
Technical field
It the utility model is related 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 on, cable possesses extraordinary resistance to elevated temperatures, heat dispersion, especially cable conductor are 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, can not continue to meet requirement.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, there is provided a kind of 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 utility model provides a kind of multicore high temperature photoelectric composite silicone rubber shield
Cable, including cable core are covered, described cable core is filled out by gap of the more insulated wire cores after twisted again between three insulated wire cores
Fill alumina-silicate ceramic fibre layer；Be sequentially provided with outside cable core thermal insulation layer, secondary shielding layer, aluminium alloy armored layer, heat-sink shell and
Silicone rubber jacket layer, described silicone rubber jacket layer outer surface coating high-temperature resistant coating layer；One group is provided with described screen layer
Symmetrical fiber unit；Described heat-sink shell is provided with a heat emission hole to stretch 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 formed.
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 combined by carbon fiber and copper is formed.
Compared with prior art, the beneficial effects of the utility model are：
1st, the gap filling alumina-silicate ceramic fibre layer between three insulated wire cores and the thermal insulation layer being provided with so that
The unit weight of cable is light, high temperature resistant, heat endurance are good, and pyroconductivity is low, thermal capacitance is small, resistance to mechanical is vibrated, expanded by heating is small, heat-insulated
Performance is good, by the extraneous heat barrier of cable outside so that the insulated wire cores service life in cable core is longer, can be at high temperature
Operation.
2nd, provided with polystyrene foam plastics layer, there is heat absorption function, the heat absorption in cable is come, and by dissipating
Hot hole discharges heat outside cable so that will not influence the stable work of cable because heat is too high 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, ensure 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 be used continuously 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.
