Abstract
The utility model relates to an anti-interference special instrument loop cable for a ship. The anti-interference special instrument loop cable is characterized in that that the anti-interference special instrument loop cable comprises a conductor, a crosslinked polyethylene (XLPE) insulating layer, a filler yarn, a unit shielding layer, an electric connecting wire, a binding band, a main shielding layer and a sheath; the crosslinked polyethylene (XLPE) insulating layer is covered outside the conductor to form wire cores; two wire cores are twisted into a twisted pair wire set; the electric connecting wire is arranged outside the twisted pair wire set; the twisted pair wire set and the electric connecting wire are respectively wrapped via the unit shielding layer to form a unit twisted pair wire set; the binding band is wrapped with four groups of the unit twisted pair wire sets; the filler yarn is respectively filled in a gap between each group of the unit twisted pair wire sets; and the main shielding layer and the sheath are respectively wrapped outside the binding band in sequence. Since the unit shielding layer and the main shielding layer are respectively arranged, the electromagnetic interference around can be effectively avoided, and the signal transmission is ensured for the instrument cable for ships; and since the sheath is arranged on the outermost layer, the main shielding layer is better protected.
Description
Affiliated technical field
The utility model relates to a kind of ships with extraordinary instrument circuit cable, belongs to the technical field of electric wires and cables of electric equipment.
Background technology
Instrument circuit cable in the electric equipment is used for the signal and the control circuit of instrument, instrument and other electric equipments, the instrument cable that uses on ships is because the space is limited, often and other cable together lay, the electromagnetism that produces during each cable energising interferes with each other the operate as normal of cable easily, especially instrument cable, bigger deviation may appear in the signal that transmits when being subjected to the interference of electromagnetism.Be difficult to guarantee ships safety in motion like this.
The utility model content
The ships that problem to be solved in the utility model provides a kind ofly can effectively prevent electromagnetic interference on every side, guarantee the signal transmission is with extraordinary instrument circuit cable.
Problem to be solved in the utility model, can realize by following technical scheme: a kind of jamproof extraordinary instrument circuit cable peculiar to vessel, it is characterized in that: comprise conductor, crosslinked polyethylene (XLPE) insulating barrier, gasket for packing, the unit screen, electrical cable, band, total screen and sheath, wherein, described crosslinked polyethylene (XLPE) insulating barrier wraps in conductor and constitutes core outward, two cores are twisted into the twisted pair wire group, described electrical cable is arranged on outside the twisted pair wire group, described twisted pair wire group and electrical cable constitute unit pair twist group by unit screen parcel, described band is enclosed with four groups of unit pair twist groups, and gasket for packing is filled the space of respectively organizing between the unit pair twist group, and described band is surrounded by total screen and sheath outward successively; Described conductor is tin-coated copper conductor or bare copper conductor; Described unit screen is tinned copper wire or bare copper wire woven shield; Described total screen is tinned copper wire, bare copper wire or zinc-coated wire braiding armouring screen; Described sheath is made by flame retardant epoxy propane (ZR-PO) or fire retardant polyolefin (ZR-XLPO) material.
On the basis of the above, core described in the utility model also comprises the flame retardant coating that is positioned between conductor and crosslinked polyethylene (XLPE) insulating barrier, to improve the fire resistance of power cable.
Compared with prior art, the utility model is provided with unit screen and total screen, and the ships that can effectively prevent electromagnetic interference on every side, guarantees the signal transmission is with extraordinary instrument circuit cable; And the utility model also is provided with sheath at outermost layer, so that protect total screen better.
