Abstract
The utility model discloses a fire-resistant control cable for a ship, which comprises a large conductor, small conductors and insulating layers. The outsides of the large conductor the small conductors are respectively coated by the insulating layers. The outsides of the insulating layers are sequentially coated by shielding layers and fire-resistant layers. Two layers of mica tapes are stacked, attached and wrapped to form a fire-resistant layer. The large conductor and the small conductors are coated by the fire-resistant layers, and the small conductors are stranded with the large conductor which serves as the centre into a bunch. The outsides of the small conductors of the bunch are sequentially coated by wrapping layers, sheath layers and armored layers. The large conductor and each of the small conductors are respectively formed by stranding a plurality of tin-coated copper wires. The resistivity of the tin-coated copper wire is less than 0.017240 Omega mm2/m (20 DEG C). The shielding layer is woven by copper wires. The control cable adopts the large conductor as the centre, and the small conductors surrounding the outside of the large conductor are stranded with the large conductor, so that the strength and the information transmission capability are improved. Meanwhile, the shielding layers are arranged on the outsides of the insulating layers of the large conductor and the small conductors, so that shielding performance of the cable is improved.
Description
Technical field:
The utility model relates to control cable peculiar to vessel field, relates in particular to a kind of fire-resistant control cable peculiar to vessel.
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 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 of normal operation under 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 relatively a little less than, do not have screen in the structure of a lot of cables, so shielding properties is just relatively poor.It is the center that the utility model adopts with 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, be enclosed with one deck screen, strengthened the shielding character of cable in the outside of the insulating barrier of big or small conductor; In addition, with the wrapped formation flame retardant coating in the bonding back of two-layer mica tape stack, strengthened the fire resistance of cable effectively, prolonged the useful life of cable under hot environment in the outside of insulating barrier.
The utility model content:
The purpose of this utility model provides a kind of control cable peculiar to vessel with fire-resistance property, the problem that the intensity that has solved traditional control cable peculiar to vessel effectively is lower, shielding properties is poor, fire resistance does not reach requirement.
The technical solution of the utility model is as follows:
Fire-resistant control cable peculiar to vessel, comprise big conductor, little conductor, insulating barrier, the outside of described big conductor, little conductor is enclosed with insulating barrier respectively, it is characterized in that: the described insulating barrier outside is enclosed with screen, flame retardant coating successively, and described flame retardant coating adopts the two-layer mica tape bonding wrapped formation that superposes; Behind described big conductor, the little conductor outer wrapping flame retardant coating, little conductor is the stranded bunchy in center with big conductor, and the outside is enclosed with lapping layer, restrictive coating, armour successively behind the bunchy.
Described fire-resistant control cable peculiar to vessel is characterized in that: described big conductor, little conductor all adopt the stranded formation of several tinned copper wires, and the resistivity of described tinned copper wire is less than 0.017240
. mm
2/ m (20 ℃).
Described fire-resistant control cable peculiar to vessel is characterized in that: described screen adopts the copper wire braiding to constitute.
Described fire-resistant control cable peculiar to vessel is characterized in that: described armour adopts the wrapped formation of copper strips.
The utility model has the advantages that:
It is the center that the utility model adopts with a big conductor, its little conductor of outer ring winding number root and with the mutual stranded bunchy of big conductor, intensity and information carrying capacity promote to some extent; Simultaneously, set up screen, improved the shielding character of cable in the outside of the insulating barrier of big or small conductor; In addition, with the wrapped formation flame retardant coating in the bonding back of two-layer mica tape stack, strengthened the fire resistance of cable effectively, prolonged the useful life of cable under hot environment in the outside of insulating barrier.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
