Abstract
The utility model discloses a flame retardation polyolefin inner sheath brass wires braided armored shipboard power cable, comprising a cable inner core. The cable inner core is formed by the stranding of a plurality of conductors, the outsides of the plurality of conductors are wrapped with insulation layers separately, and the outside of the cable inner core is wrapped with a lapping layer, a shielding layer, an inner sheath and a sheath in turn. The flame retardation polyolefin inner sheath brass wires braided armored shipboard power cable of the utility model is simple in structure, has very high water resistance, insulation property and flame retardancy, and the sheath made up of the polyolefin material can adapt to work in subaqueous and dry cabin environments completely. Meanwhile, the shielding effect of the shipboard power cable is improved by arranging the shielding layer, and the intensity of the shipboard power cable is improved by employing a tinned annealed copper wire to braid the outer layer armoring of the shipboard power cable.
Description
Technical field
The utility model relates to a kind of fire retardant polyolefin inner sheath copper wire braiding armouring ship power cable.
Background technology
Work in the cabin of underwater environments such as ship power cable is the cable that is used to transmit and distribute electric energy, the rivers,lakes and seas of being everlasting and drying.In power circuit peculiar to vessel, the shared proportion of cable increases just gradually.Ship power cable be master in electric power system peculiar to vessel in circuit in order to transmission with distribute the cable product of high-power electric energy, comprising 1-500KV and above various electric pressure, the power cable of various insulation.
Because the particularity of ship power cable environment for use, so require the water proofing property of ship power cable to want high, insulation property will be got well, and fire resistance is eager to excel, and the intensity of cable itself wants high simultaneously, and antijamming capability is eager to excel.
The utility model content
The purpose of this utility model provides a kind of fire retardant polyolefin inner sheath copper wire braiding armouring ship power cable, adopt the material of polyolefine material as sheath, improve water proofing property, insulating properties and the anti-flammability of ship power cable, the shield effectiveness that screen improves ship power cable is set simultaneously, and the employing tin annealed copper wire is woven into the outer armouring of ship power cable, improves the intensity of ship power cable.
The technical solution of the utility model is as follows:
