Abstract
The utility model discloses a fire resistant polyvinyl chloride inner sheath steel wire 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 two sides of the plurality of conductors are equipped with filling cores respectively, a fire-resistant layer and an insulating layer are clad on the outside of each conductor in turn, and a lapping layer, an inner sheath and a sheath are clad in turn on the outside of the cable inner core. The fire resistant polyvinyl chloride inner sheath steel wire braided armored shipboard power cable of the utility model is simple in structure, has very high water resistance, insulation property and fire resistance, and the sheath made up of the polyvinyl chloride material can adapt to work in subaqueous and dry cabin environments completely. Meanwhile, by employing the tinned steel wire to braid the outer layer armoring of the shipboard power cable, the intensity of the shipboard power cable is improved, and by arranging filling cores at the two sides of the conductors, the moisture proof and insulation effects are realized.
Description
Technical field
The utility model relates to a kind of fire-resistant polyvinyl chloride inner sheath braided steel wire 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 drying property will be got well.
The utility model content
The purpose of this utility model provides a kind of fire-resistant polyvinyl chloride inner sheath braided steel wire armouring ship power cable, adopt the material of pvc material as sheath, and water proofing property, insulating properties and the fire resistance that flame retardant coating improves ship power cable be set outside conductor, adopt tin plated steel wire to be woven into the outer armouring of ship power cable simultaneously, improve the intensity of ship power cable, and the both sides at conductor are provided with filled core, play a part moistureproof and insulation.
