Abstract
The utility model discloses a crosslinked polyvinyl chloride shrouded cable for vessel control comprising a large conductor and a small conductor wrapped by an insulating layer and adopting a complex bunch strand mode. The pitch to height ratio thereof is less than 10 times. After being wrapped by the insulating layer, the large conductor and the small conductor are stranded into a bunch taking the large conductor as centre, the insulating layer of the stranded small conductor is wrapped by a taped covering, a diagonal is set inside the taped covering and a shroud layer and an armour layer are orderly wrapped outside the taped covering. The small conductor is formed by stranded tin plated copper wire whose electric resistance is less than 0.017241 omega.mm2/m (20 degrees centigrade). The armour layer is formed by knitted bare copper wire. The utility model is simple in structure, able to enhance the strength by adopting a large conductor as centre and winding multiple small conductors outside it and stranding them into a bunch and to increase the information transmission capacity by diagonal set in the taped covering.
Description
Technical field:
The utility model relates to control cable peculiar to vessel field, relates in particular to a kind of pvc sheath control cable peculiar to vessel.
Background technology:
Cable is in order to transmit electricity (magnetic) ability, information and the wire product of realizing the electromagnetic energy conversion.
Shipboard cable comprises that ship power cable, control cable peculiar to vessel, cable for telecommunication of ships, naval vessel are with control cable etc.Mainly be applicable to transmission of aquatic building thing and electrical equipment control such as various rivers seagoing vessel oceangoing ship and offshore oil platform.
Traditional control cable peculiar to vessel mostly adopts the identical stranded bunchy of conductor of several thicknesses, the intensity of cable relatively a little less than.It is the center that the utility model adopts a big conductor, its little conductor of outer ring winding number root and with the mutual stranded bunchy of big conductor, not only intensity has increased greatly, and information carrying capacity also promotes to some extent; Simultaneously, in lapping layer, also be provided with twisted pair wire, also help information carrying capacity to promote.
The utility model content:
The purpose of the utility model provides the inside and outside sheath of a kind of polyvinyl chloride control cable peculiar to vessel, has solved the problem that intensity is lower, fire resistance is low of traditional control cable peculiar to vessel with fire resistance effectively.
The technical scheme of the utility model is following:
Cross-linked polrvinyl chloride sheath control cable peculiar to vessel; Comprise big conductor, little conductor; The outside of described big conductor, little conductor is enclosed with insulating barrier respectively, it is characterized in that: described big conductor and described little conductor all adopt compound bundle strand, and the twisting pitch ratio is less than 10 times; Behind described big conductor and the described little conductor wrap insulate layer; With described big conductor is the stranded bunchy in center; The insulating barrier of little conductor is wrapped with lapping layer behind the bunchy, is provided with twisted pair wire in the described lapping layer, and the described lapping layer outside is enclosed with restrictive coating, armour successively.
Described cross-linked polrvinyl chloride sheath control cable peculiar to vessel is characterized in that: described little conductor adopts the stranded formation of tinned copper wire, and the resistivity of described tinned copper wire is less than 0.017241
. mm
2/ m (20 ℃).
Described cross-linked polrvinyl chloride sheath control cable peculiar to vessel is characterized in that: described armour adopts the bare copper wire braiding to constitute.
The utility model has the advantages that:
The utility model simple in structure, adopting a big conductor is the center, its little conductor of outer ring winding number root and with the mutual stranded bunchy of big conductor, not only intensity has increased greatly, has set up diagonal in the lapping layer simultaneously, information carrying capacity also promotes to some extent.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Cross-linked polrvinyl chloride sheath control cable peculiar to vessel comprises big conductor 1, little conductor 2, and the outside of big conductor 1, little conductor 2 is enclosed with insulating barrier 3 respectively, and big conductor 1 all adopts compound bundle strand with little conductor 2, and twisting pitch is than less than 10 times; Behind big conductor 1 and the little conductor wrap insulate layer 3; With big conductor 1 is the stranded bunchy in center; The insulating barrier 3 of little conductor 2 is wrapped with lapping layer 4 behind the bunchy, is provided with twisted pair wire 5 in the lapping layer 4, and lapping layer 4 outsides are enclosed with restrictive coating 6, armour 7 successively; Little conductor 2 adopts the stranded formation of tinned copper wire, and the resistivity of tinned copper wire is less than 0.017241
. mm
2/ m (20 ℃), armour 7 adopt the bare copper wire braiding to constitute.
