Abstract
The utility model discloses an anti -interference and thermal -insulated type coaxial cable, including a plurality of copper clad aluminium inner conductors, the every outer extrusion molding of copper clad aluminium inner conductor has the electrically conductive insulating layer of expanded polyethylene material, electrically conductive insulating layer is equipped with the woven shield that the constitution was woven to copper clad aluminium silk thread outward in proper order, the external insulation layer constitutes insulation core, insulation core extrusion molding is in the elastic layer of polyurethane elastomer material, the elastic layer outside is equipped with at a distance from the oxygen layer in proper order, the insulating layer that double -deck ceramic fiber band constitutes around the package, the outer extrusion molding of insulating layer has the inner sheath layer, the oversheath layer, there are a plurality of copper clad aluminium outer conductors along annular interval distribution between inner sheath layer and the oversheath layer, every copper clad aluminium outer conductor outward in proper order the cladding have the aluminium foil to wind the covering, silicone rubber insulating layer. The utility model discloses an interior outer conductor the cost is reduced of aluminum core copper wire matter, simultaneously, cable overall structure optimizes, has improved the shielding property of cable, the life in the high temperature environment work.
Description
Technical field:
The utility model relates to coaxial cable, particularly relates to a kind of anti-interference and heat insulation type coaxial cable.
Background technology:
Coaxial cable adopts copper as conductor mostly, current nonferrous metal price rises suddenly and sharply, copper conductor cost accounts for more than 90% of cable raw material total cost, therefore, need to find suitable material can ensure to meet the technical indicator of cable copper conductor, significantly can reduce the important topic that cable cost is cable industry again.
Currently marketed most coaxial cable is when the effect being subject to external force, frequent appearance distortion, comparatively large to the damage of cable core, even occur that Signal transmissions interrupts, bring huge loss, the shielding properties, heat-proof quality etc. of certain cable can not meet the Signal transmissions between high precision apparatus.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of anti-interference and heat insulation type coaxial cable, effectively reduce the cost of cable, also improve the shielding properties of cable, heat insulation resistance to elevated temperatures in high-temperature work environment simultaneously, extend useful life.
The technical solution of the utility model is as follows:
Anti-interference and heat insulation type coaxial cable, it is characterized in that: comprise some copper cover aluminum inner wires, the outer extrusion moulding of every root copper cover aluminum inner wire has the conduction insulating barrier of polyethylene foamed material, conduction insulating barrier is provided with the woven shield that the braiding of copper cover aluminum silk thread is formed outward successively, external insulation layer forms insulated wire cores, insulated wire cores extrusion moulding is in the elastic layer of polyurethane elastomer material, oxygen barrier layer is provided with successively outside elastic layer, the thermal insulation layer of the wrapped formation of double-layer ceramic fabric strip, the outer extrusion moulding of thermal insulation layer has inner restrictive coating, external sheath layer, some copper cover aluminum outer conductors are distributed with along annular space between inner restrictive coating and external sheath layer, every root copper cover aluminum outer conductor is coated with aluminium foil lapping layer outward successively, silicone rubber insulation layer.
Described anti-interference and heat insulation type coaxial cable, is characterized in that: the wrapped coverage rate of double-layer ceramic fabric strip of described thermal insulation layer reaches 100%.
The utility model has the advantages that:
The utility model adopts the internal and external conductor of copper cover aluminum material to reduce cost, and meanwhile, whole cable structure optimization, improves the useful life in the shielding properties of cable, hot environment work.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
See accompanying drawing:
Anti-interference and heat insulation type coaxial cable, comprise some copper cover aluminum inner wires 1, the outer extrusion moulding of every root copper cover aluminum inner wire 1 has the conduction insulating barrier 2 of polyethylene foamed material, the outer woven shield 3 being provided with the braiding of copper cover aluminum silk thread successively and forming of conduction insulating barrier 2, external insulation layer 4 forms insulated wire cores, insulated wire cores extrusion moulding is in the elastic layer 5 of polyurethane elastomer material, oxygen barrier layer 6 is provided with successively outside elastic layer 5, the thermal insulation layer 7 of the wrapped formation of double-layer ceramic fabric strip, the outer extrusion moulding of thermal insulation layer 7 has inner restrictive coating 8, external sheath layer 9, some copper cover aluminum outer conductors 10 are distributed with along annular space between inner restrictive coating 8 and external sheath layer 9, every root copper cover aluminum outer conductor is coated with aluminium foil lapping layer 11 outward successively, silicone rubber insulation layer 12.
The wrapped coverage rate of double-layer ceramic fabric strip of thermal insulation layer 7 reaches 100%.
