Abstract

The utility model discloses a control cable for ship and with a neoprene inner sheath and a polyvinyl chloride (PVC) outer sheath, which comprises three conductors arranged in a shape of a Chinese character 'pin'. A fireproof layer and an insulation layer are wrapped outside the conductors in sequence. The conductors wrapped by the insulation layer are twisted into a bunch, twisting pitch ratio is less than 14, and the bunch is wrapped by a binding layer and an inner sheath layer in sequence. The inner sheath layer is wrapped by an armored layer formed by twisting copper foil bans, and a plurality of steel wires are distributed along an inner ring of the armored layer, the diameter of the steel wires ranges from 0.2 mm to 2mm, an outer sheath layer is formed outside the armored layer by extrusion, the inner sheath is made of neoprene and the outer sheath is made of PVC. The control cable for the ship and with the neoprene inner sheath and the polyvinyl chloride (PVC) outer sheath is novel in stricture. The armored layer of the cable is formed by wrapping the copper foil bands, steel wires distributed in a circular shape are arranged inside the cable so as to improve strength of the cable, shielding performance and stability for transmitting signals of the cable.

Description

A kind of neoprene rubber inner sheath polyvinyl chloride oversheath control cable peculiar to vessel

Technical field:

The utility model relates to control cable peculiar to vessel field, relates in particular to a kind of neoprene rubber inner sheath polyvinyl chloride oversheath 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.

So-called fire-resisting cable can keep circuit complete or can keep the cable that normally moves down at the flame condition of regulation exactly in burning situation within a certain period of time.

Traditional control cable peculiar to vessel mostly adopts the identical stranded bunchy of several conductors of several thicknesses, the intensity of cable and shielding properties relatively a little less than.

The utility model content:

The purpose of the utility model provides a kind of neoprene rubber inner sheath polyvinyl chloride oversheath control cable peculiar to vessel, thereby the intensity that has solved traditional control cable peculiar to vessel effectively is lower, the shielding properties difference influences the problem that information is transmitted.

The technical scheme of the utility model is following:

Neoprene rubber inner sheath polyvinyl chloride oversheath control cable peculiar to vessel comprises three conductors of arranging in a triangle, and conductor is enclosed with flame retardant coating, insulating barrier outward successively respectively; The mutual stranded bunchy of the conductor of wrap insulate layer; The twisting pitch ratio is less than 14 times, and the outside is enclosed with belting layer, inner restrictive coating successively behind the bunchy, and it is characterized in that: inner restrictive coating is wrapped with armour; Armour adopts the wrapped formation of Copper Foil band; Along annular spread several steel wires are arranged in the armour, several gauge of wire scope 0.2-2mm, the outer extrusion moulding of armour has external sheath layer.

Described neoprene rubber inner sheath polyvinyl chloride oversheath control cable peculiar to vessel is characterized in that: it is the neoprene rubber that described inner restrictive coating adopts material.

Described neoprene rubber inner sheath polyvinyl chloride oversheath control cable peculiar to vessel is characterized in that: external sheath layer adopts polyvinyl chloride.

The utility model has the advantages that:

The utility model novel structure, armature of cable layer adopt the wrapped formation of Copper Foil band, in be provided with the steel wire of annular spread, played the effect that strengthens cable intensity, also can be used as the performance that reaches shielding, improved the stability that cable transmits signal.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Embodiment:

Neoprene rubber inner sheath polyvinyl chloride oversheath control cable peculiar to vessel comprises three conductors of arranging in a triangle 1, conductor 1 outer flame retardant coating 2, the insulating barrier 3 of being enclosed with respectively successively; The conductor 1 mutual stranded bunchy of wrap insulate layer 3, the twisting pitch ratio is less than 14 times, and the outside is enclosed with belting layer 4, inner restrictive coating 5 successively behind the bunchy; Inner restrictive coating 4 is wrapped with armour 6, and armour 6 adopts the wrapped formation of Copper Foil band, and having played simultaneously in the effect armour 6 that shields has several steel wires 7 along annular spread; The diameter range 0.2-2mm of several steel wires 7; Also can be used as drainage thread and use, improved the stability of cable transmission signal, armour 6 outer extrusion moulding have external sheath layer 8; It is the neoprene rubber that inner restrictive coating 5 adopts material, and external sheath layer 8 adopts polyvinyl chloride.
