Abstract
The utility model discloses a marine control cable having fire resistant property, comprising a large conductor, small conductors and insulating layers, wherein an outboard of the large conductor and outboards of the small conductors are all respectively covered with an insulating layer and a fireproof layer, and the fireproof layer is prepared by two layers of superposed, bonded and winded mica tapes; after the fireproof layers are wrapped, the small conductors and the large conductor are twisted to form a cluster with the large conductor being the center, an outboard of the cluster is successively covered by a winding layer, a sheath layer and an armor layer, the large conductor and the small conductors are all prepared by a plurality of tin-coated copper filaments, and resistivity of the tin-coated copper filament is less than 0.017241 omega*mm2/m (20 DEG C). Structure of the cable is simple, the large conductor serves as the center, a plurality of small conductors encircle the large conductor, and the small conductors and the large conductor are twisted to form a cluster, so intensity is substantially increased, information transmission capability is improved, and at the same time; and the fireproof layer is prepared by two layers of superposed, bonded and winded mica tapes, so fireproof performance of the cable is effectively enhanced.
Description
Technical field:
The utility model relates to the shipboard cable field, relates in particular to a kind of control cable peculiar to vessel with fire-resistance property.
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 conductor of several thicknesses, the intensity of cable relatively a little less than.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, 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 the utility model provides a kind of control cable peculiar to vessel with fire-resistance property, has solved the lower problem of intensity of traditional control cable peculiar to vessel with fire resistance effectively.
The technical scheme of the utility model is following:
Control cable peculiar to vessel with fire-resistance property; Comprise big conductor, little conductor, insulating barrier; It is characterized in that: the outside of described big conductor, little conductor is enclosed with insulating barrier, flame retardant coating successively respectively, and described flame retardant coating adopts the two-layer mica tape bonding wrapped formation that superposes; Behind the parcel flame retardant coating, described little conductor is the stranded bunchy in center with described big conductor, and the outside is enclosed with lapping layer, restrictive coating, armour successively behind the bunchy.
Described control cable peculiar to vessel with fire-resistance property 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 0.017241
. mm
