Abstract
The utility model discloses a cable for a crosslinked polyvinyl chloride sheath ship. The cable comprises a large conductor and a small conductor, wherein the outer sides of the large conductor and the smaller conductor are respectively wrapped with an insulation layer, the large conductor is formed by adopting the sixth type beam twisted soft round copper wires or tinned copper wires, the single-wire diameter of the conductors is below 0.18mm, the twisted pitch ratio is 10 to 12 times, the small conductor wrapped with the insulation layer uses the large conductor wrapped with the insulation layer as the center to be twisted into beams for forming a cable core, a belt wrapping layer is wrapped outside the cable core, twisted pair wires are arranged in the belt wrapping layer in a triangular shape, and the outer side of the belt wrapping layer is sequentially wrapped with an inner sheath layer, an armor layer and an outer sheath layer. The cable has the advantages that the structure is simple, the large conductor is used as the center, in addition, a plurality of small conductors are surrounded at the outer side, beams are simultaneously twisted for forming the cable core, the twisted pair wires in the belt wrapping layer are matched, on one hand, the structure intensity of the cable is improved, and on the other hand, the information transmission capability is improved.
Description
Technical field:
The utility model relates to field of cables, relates in particular to a kind of cross-linked polrvinyl chloride sheath marine cable.
Background technology:
Cable is in order to transmit electricity (magnetic) energy, the wire product of information and the conversion of realization electromagnetic energy.Shipboard cable comprises ship power cable, control cable for boat, cable for telecommunication of ships, inflaming retarding ship-use control cable etc.Mainly be applicable to waterborne building transmission and the electrical equipment control such as various rivers seagoing vessel oceangoing ship and offshore oil platform.
Traditional control cables peculiar to vessel mostly adopts the identical stranded bunchy of conductor of several thicknesses, the intensity of cable relatively a little less than.Therefore the structural strength and the information carrying capacity that how to improve cable are current problem demanding prompt solutions.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides a kind of cross-linked polrvinyl chloride sheath marine cable, reasonable in design, and the structural strength that has effectively improved cable is lower, the unsettled problem of transmission of information.
