Abstract
The utility model discloses a heat-radiation-type instrument control cable. The cable comprises a plurality of conductors, wherein the conductors each is coated by a silicone rubber insulation layer so as to form an insulation wire core; the insulation wire cores are stranded into a cable core; and the cable core is sequentially coated by a wrapping layer and a composite sheath layer, the composite sheath layer being composed of an inner tin-coated brass wire woven layer and an outer crosslinked polyethylene protection layer, and the outer crosslinked polyethylene protection layer being internally provided with heat radiation tubes. According to the utility model, the heat-radiation-type instrument control cable has the advantages of reasonable structure, safety, reliability, strong anti-interference performance and good flame retardant performance; the outer crosslinked polyethylene protection layer is internally provided with the heat radiation tubes, facilitating the effective radiation of the heat generated by the cable; besides, drainage wires are additionally arranged on the inner layer of the composite sheath layer, so that the safety of using the cable is improved.
Description
Technical field
The utility model relates generally to technical field, relates in particular to a kind of heat radiating type instrumentation control cable.
Background technology
China's economic growth continuously and healthily, for cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight, reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry allows the world regard with special esteem.Along with the continuous expansion of the industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire industry also has huge development potentiality.
The application of electronic computer, instrument and meter is day by day universal, and people's awareness of safety constantly strengthens, and performance and the environmental requirement of the cable supporting with it also improved constantly.Existing computer and instrument are high temperature resistant not high with fire resistance with cable, and the security reliability of cable is low under fire condition, and shielding properties and interference free performance are not high, are not suitable for use in densely populated and higher to device security reliability requirement place.
Therefore, be badly in need of a kind of anti-flammability, anti-interference is good, safe heat radiating type instrumentation control cable.
The utility model content
The utility model purpose is to provide a kind of heat radiating type instrumentation control cable, and structural design is reasonable, has good anti-flammability, anti-interference and heat dispersion.
The utility model is achieved through the following technical solutions:
The heat radiating type instrumentation control cable; include several conductors; it is characterized in that: described several conductors are coated with respectively silicone rubber insulation layer outward and consist of insulated wire cores; the mutual stranded bunchy of insulated wire cores consists of cable core; cable core is provided with lapping layer, composite jacket layer outward successively; the composite jacket layer is made of tincopper fuse wire braided armor and the outer field crosslinked polyethylene protective layer of internal layer, is provided with radiating tube in the crosslinked polyethylene protective layer.
Described heat radiating type instrumentation control cable is characterized in that: be provided with several drainage threads between described tincopper fuse wire braided armor and lapping layer.
The utility model has the advantages that:
The utility model reasonable in design, safe and reliable, strong interference immunity and fire resistance are good, are provided with the heat loss that radiating tube can produce cable effectively in the composite jacket layer, simultaneously set up drainage thread at the internal layer of composite jacket layer, strengthened the fail safe that cable uses.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1; the heat radiating type instrumentation control cable; include several conductors 1; the outer silicone rubber insulation layer 2 that is coated with respectively of several conductors 1 consists of insulated wire cores; the mutual stranded bunchy of insulated wire cores consists of cable core; cable core is provided with lapping layer 3, composite jacket layer 4 outward successively, and composite jacket layer 4 is made of tincopper fuse wire braided armor 4-1 and the outer field crosslinked polyethylene protective layer 4-2 of internal layer, is provided with radiating tube 5 in crosslinked polyethylene protective layer 4-2.
Be provided with several drainage threads 6 between tincopper fuse wire braided armor 4-1 and lapping layer 3.
Lapping layer 3 can adopt resistant to elevated temperatures glass fibre belt overlapping wrapped.
