Abstract
The utility model discloses a low-smog halogen-free environmental friendly clean cable comprising a plurality of inner conductors and a plurality of outer conductors; the plurality of inner conductors and the plurality of outer conductors are respectively provided with crosslinking polyethylene insulating layers to form a plurality of inner insulation wire cores and a plurality of outer insulation wire cores; the plurality of inner insulation wire cores are arranged in an annular manner around a center of an elastic rope extruded by a polyurethane elastomer; a bundle core is arranged in a center of the elastic rope; an inner nylon protection layer is arranged outside the plurality of inner insulation wire cores; the plurality of outer insulation wire cores are distributed in an annular manner outside the inner nylon protection layer; an outer nylon protection layer is arranged outside the plurality of outer insulation wire cores to form a cable core; and a low-smog halogen-free polyolefin sheath layer is arranged outside the cable core. The low-smog halogen-free environmental friendly clean cable is reasonable in design, employs the nylon protection layers positioned outside the plurality of inner conductors and outer conductors, so structure compactness and flame resistance property of the cable are obviously improved; furthermore, the elastic rope is employed to be the center of the plurality of inner conductors, so stretch-proofing property is improved, and simultaneously structure compactness of the cable is further improved.
Description
Technical field:
The utility model relates to power cable, relates in particular to a kind of low smoke and zero halogen environment-protecting clean cable.
Background technology:
Along with expanding economy, all trades and professions have different requirements to the performance of cable.The materials such as the insulation of general cable and sheath, if consisted of by the polymer of Halogen, general PVC insulation PVC sheathed plastic cable for example, when burning, can produce poisonous corrosivity halogenation gas and smog, will corrode instrument and equipment, infringement people's health, even threat to life.
For the power cable of environment friendly and clean type, structural compactness and fire resistance are relatively poor all the time, how so that the two is taken into account, are problem demanding prompt solutions so that cable satisfies the practical service environment demand fully.
The utility model content:
In order to solve the deficiencies in the prior art, the purpose of this utility model provides a kind of low smoke and zero halogen environment-protecting clean cable, and structural compactness and fire resistance are good, with environmental nonpollution.
The technical solution of the utility model is as follows:
Low smoke and zero halogen environment-protecting clean cable, comprise several inner wires, several outer conductors, it is characterized in that: described several inner wires, several outer conductors are provided with respectively crosslinked polyetylene insulated layer outward and consist of several interior insulated wire cores, several external insulation cores, described several interior insulated wire cores centered by the elastic threads of polyurethane elastomer extrusion moulding along annular spread, the elastic threads center is provided with Shu Xin, described several interior insulated wire cores is provided with interior nylon overcoat outward, interior nylon overcoat outer annular spread has several external insulation cores, several external insulation cores are provided with outer nylon overcoat outward and consist of cable core, and cable core is provided with the low-smoke halogen-free polyolefin restrictive coating outward.
Described low smoke and zero halogen environment-protecting clean cable is characterized in that: described bundle core adopts carbon fiber wire and the stranded bunchy of aramid fiber yarn to consist of.
The utility model has the advantages that:
The utility model reasonable in design, adopt the periphery of several inner wires, several outer conductors to be provided with the nylon overcoat, so that the structural compactness of cable and fire resistance are obviously promoted, in addition, several inner wires are centered by elastic threads, further promote the structural compactness of cable when having improved the stretch-proof performance, satisfied actual environment for use.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
