Abstract
The utility model discloses a low temperature resistant electric cable having a heat tracing structure. The low temperature resistant electric cable having a heat tracing structure comprises a plurality of conductors, each conductor is formed by intertwisting 68 tinned soft copper wires around a carbon fiber filament bundle serving as a center, the tinned soft copper wires are 0.34 m in diameter, all the plurality of conductors are orderly covered with thermal insulation glass fiber woven layers and crosslinked polyethylene insulating layers and therefore insulation wire cores are formed, a cable core is formed by lengthwise arranging the insulation wire cores in such a way that a quadrangle is formed, the cable core is made into a cable after being formed on a polyester rubber protection sleeve layer through plastic extrusion molding operation, and the center of the cable core is provided with a heat tracing band. The low temperature resistant electric cable is characterized in that the structure is reasonable; conductors are made by intertwisting a plurality of wires and filament bundles; the conductors are characterized by softness, round and integrated structure, stability, and ensured communication quality; the protection sleeve is made of a polyester rubber material and is characterized by excellent bend and fatigue resistant performance, good anti-tear and high-tension properties, and maintenance of good tenacity and resilience at a low temperature; the center of the cable core is provided with the heat tracing band, normal work of the protection sleeve and the cable core within a certain temperature range can be ensured, and the service life can be prolonged.
Description
Technical field:
The utility model relates to cable, relates in particular to a kind of low temperature resistant cable with companion's heat structure.
Background technology:
Traditional cable is constructed to lay and just be there will be cable insulation and sheath cracking in cold environment, once moving appears in this cable, insulation and sheath not only ftracture, but also can come off, and conductor exposes and cannot use, and affects the normal operations such as equipment.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of low temperature resistant cable with companion's heat structure, and structural design novelty has improved the resistance to low temperature of cable, the patency that guarantee information is transmitted.
The technical solution of the utility model is as follows:
With the low temperature resistant cable of companion's heat structure, comprise many conductors, it is characterized in that: zinc-plated soft copper silk stranded formation centered by carbon fibre tow that it is 0.34m that many described conductors all adopt 68 diameters, many conductors are all coated with heat insulation glass silk braid, crosslinked polyetylene insulated layer formation insulated wire cores outward successively, insulated wire cores becomes square longitudinally to discharge formation cable core, cable core is through extrusion moulding in lactoprene restrictive coating stranding, and the center of cable core is provided with heating tape.
The utility model has the advantages that:
1, the utility model reasonable in design, conductor adopts multifibres bundle strand, and not only softness, structure rounding, stable, ensure communication quality;
2, sheath of the present utility model adopts lactoprene material, has excellent counter-bending fatigue behaviour, good tear resistance and high tensile, keeps good toughness and resilience at low temperatures;
3,, when conductor of the present utility model center is provided with carbon fibre tow and has improved the tensile property of cable, do not affect the flexibility of cable yet.
4, the utility model is provided with heating tape at cable core center, can ensure that restrictive coating and cable core work normally in certain temperature range, increases the service life.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
With the low temperature resistant cable of companion's heat structure, comprise many conductors 1, zinc-plated soft copper silk stranded formation centered by carbon fibre tow 2 that it is 0.34m that many conductors 1 all adopt 68 diameters, many outer heat insulation glass silk braid 3, the crosslinked polyetylene insulated layer 4 formation insulated wire cores of being all coated with successively of conductor 1, insulated wire cores becomes square longitudinally to discharge formation cable core, cable core is through extrusion moulding in lactoprene restrictive coating 5 strandings, and the center of cable core is provided with heating tape 6.
