The flame retardation polyolefin inner/outer sheath shipboard power cable of the utility model is simple in structure, and is easy to realize, the flame retardation capacity and security of the power cable can be improved effectively thanks to the polyolefin inner sheath and the polyolefin outer sheath arranged on the outside of the conductor core, the corrosion resistance capacity of the power cable is enhanced effectively thanks to the corrosion resistance layer, and the intensity of the power cable is enhanced effectively thanks to the fillers.
Description
Technical field
The utility model relates to the power cable field, is specially the inside and outside sheath ship power cable of a kind of fire retardant polyolefin.
Background technology
Power cable is the electric equipment that is used to transmit and distribute electric energy.In power circuit, the shared proportion of cable increases just gradually.It is transmission and distribute high-power electric energy in the basic routing line of electric power system that power cable mainly acts on.Modern steamer electrifing degree is higher, need use a large amount of power cables and carry out electric energy transmitting, and modern steamer has requirement for the flame-retarding characteristic of power cable, and traditional power cable can't satisfy the demand of modern steamer.
The utility model content
The purpose of this utility model provides the inside and outside sheath ship power cable of a kind of fire retardant polyolefin, can't satisfy the problem of modern steamer demand with the power cable flame-retarding characteristic that solves prior art.
In order to achieve the above object, the technical scheme that the utility model adopted is:
The inside and outside sheath ship power cable of fire retardant polyolefin, it is characterized in that: the conductor thread core that includes two compound bundle strands, described conductor thread core by copper conductor, be enclosed within the outer crosslinked polyetylene insulated cover of copper conductor and constitute, the twisting pitch ratio of two conductor thread cores is less than 10 times, and copper conductor resistivity is less than 0.017241 Ω .mm
2/ m, two conductor thread core outsides are coated with twining package tape, polyolefin inner sheath, braided steel wire armour, polyolefin oversheath, anti-corrosion layer successively, and the space is filled with filler between described conductor thread core and the twining package tape.The inside and outside sheath ship power cable of described fire retardant polyolefin is characterized in that: described copper conductor surface is coated with the tin layer.
The inside and outside sheath ship power cable of described fire retardant polyolefin is characterized in that: described braided steel wire armour is formed by the braided steel wire that the surface is coated with the zinc-tin layer.
The utility model is simple in structure, is easy to realize.Conductor thread core plays the effect of electric energy transmitting, by compound bundle strand two conductor thread cores are twisted together, and twisting pitch can guarantee the power cable compact conformation than less than 10 times, and reduce the loss of electric energy, copper conductor resistivity is less than 0.017241 Ω .mm
2/ m can improve the efficiency of transmission of electric energy, be woven into the steel wire external galvanized layer tin layer of braided steel wire armour, prevent the oxidative phenomena in the course of processing and use, the outer inside and outside sheath of polyolefin of conductor thread core can improve the fire retardancy of power cable effectively, also improved the fail safe of power cable, anti-corrosion layer has strengthened the erosion-resisting ability of power cable effectively, and the filler in space has strengthened the intensity of power cable effectively between conductor thread core and the twining package tape.
