Abstract
The utility model relates to a novel marine special instrument loop cable, which is characterized in that a conductor, an XLPE (Cross Linked Polyethylene) insulation layer, a filling rope, a tape, a sheath and a shielding layer are included, wherein the XLPE insulation layer wraps the conductor to form two cores, and the two cores are twisted into four groups of twisted pairs; the tape wraps the twisted pairs, and the filling rope is filled in the gap among the twisted pairs; the sheath and the shielding layer wrap the tape in sequence; the conductor adopts a tinned copper conductor or a naked copper conductor; the sheath is made of ZR-PO (zirconium-polyolefin)or ZR-XLPO (zirconium-cross linked polyolefin) material; and the shielding layer adopts an armored shielding layer weaved by a tinned copper wire, a naked copper wire or a galvanized steel wire. The shielding layer is arranged at the outermost layer, so that the electromagnetic interference is prevented effectively, and the normal operation of signals and a control circuit is guaranteed; moreover, all components of the novel shipboard special instrument loop cable are made of materials conforming to the environmental protection requirements, so that the flame resistance of the novel shipboard special instrument loop cable is high, and no toxic substance is caused during combustion of the novel shipboard special instrument loop cable.
Description
Affiliated technical field
The utility model relates to a kind of novel ships with extraordinary instrument circuit cable, belongs to the technical field of electric wires and cables of electric equipment.
Background technology
Various cables all can produce electromagnetism in use, the instrument cable of on ships, laying, because the space is limited, often multiple cable or many cables are together laid, the electromagnetism that produces during each cable energising interferes with each other the operate as normal of cable easily, especially instrument cable, signal and control circuit that it is used for instrument, instrument and other electric equipments, bigger deviation may appear in the signal that transmits when being subjected to the interference of electromagnetism.Because ships often travels in the waters, during breaking out of fire, need instrument cable under the state of burning, to keep certain operating time, and can not produce poisonous material, in addition to save oneself or to wait for rescue; Therefore the marine instrumentation cable has higher requirement on the fire-fighting performance.
The utility model content
Problem to be solved in the utility model provides and a kind ofly can prevent that electromagnetic interference, fire-resistant and burning from the time can not produce the peculiar to vessel extraordinary instrument circuit cable of noxious substance.
Problem to be solved in the utility model, can realize by following technical scheme: the extraordinary instrument circuit cable of a kind of New Marine, it is characterized in that: comprise conductor, crosslinked polyethylene (XLPE) insulating barrier, gasket for packing, band, sheath and screen, wherein, described crosslinked polyethylene (XLPE) insulating barrier wraps in conductor and constitutes core outward, and two cores are twisted into the twisted pair wire group; Described band wraps in outside four groups of twisted pair wire groups, and gasket for packing is filled the space between each twisted pair wire group; Described band is surrounded by sheath and screen outward successively; Described conductor is tin-coated copper conductor or bare copper conductor; Described sheath is made by flame retardant epoxy propane (ZR-PO) or fire retardant polyolefin (ZR-XLPO) material; Described screen is tinned copper wire, bare copper wire or zinc-coated wire braiding armouring screen.
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 resistant flame retardant performance of cable.
Compared with prior art, the utility model is provided with screen at outermost layer, can effectively prevent electromagnetic interference, guarantee the operate as normal of signal and control circuit, and the utility model adopted each building block of made of compliance with environmental protection requirements, can not produce noxious substance when making the high and burning of fire resistance of the present utility model.
