Abstract
The utility model discloses a power cable for a ship with a flame-retardant polyolefin inner jacket and a polyvinyl chloride outer jacket. The power cable comprises conductor cores, wherein each conductor core consists of a copper conductor, a shielding layer and a cross-linked polyethylene insulating sleeve; and a tape, a polyvinyl chloride inner jacket, a steel wire woven armor layer, a cross-linked polyethylene outer jacket and a corrosion-resistant layer are arranged outside the conductor cores. The power cable has a simple structure, and is easy to realize; by adopting the polyolefin inner jacket and the polyvinyl chloride outer jacket outside the conductor cores, the flame retardance of the power cable can be enhanced effectively, and the safety of the power cable is enhanced; and by adopting the corrosion-resistant layer, the corrosion resistance of the power cable is enhanced effectively.
Description
Technical field
The utility model relates to the power cable field, is specially a kind of fire retardant polyolefin inner sheath, polyvinyl chloride oversheath ship power cable.
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 a kind of fire retardant polyolefin inner sheath, polyvinyl chloride oversheath ship power cable, 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:
Fire retardant polyolefin inner sheath, polyvinyl chloride oversheath ship power cable, it is characterized in that: the conductor thread core that includes two compound bundle strands, screen, crosslinked polyetylene insulated cover that described conductor thread core is enclosed within outside the copper conductor by copper conductor, successively 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, polyvinyl chloride oversheath, anti-corrosion layer successively.Described fire retardant polyolefin inner sheath, polyvinyl chloride oversheath ship power cable is characterized in that: described copper conductor surface is coated with the tin layer.
Described fire retardant polyolefin inner sheath, polyvinyl chloride oversheath ship power cable 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, screen outside the copper conductor is shielding electromagnetic wave effectively, 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, polyolefin inner sheath outside the conductor thread core, the fire retardancy that the polyvinyl chloride oversheath can improve power cable effectively, also improved the fail safe of power cable, anti-corrosion layer has strengthened the erosion-resisting ability of power cable effectively.
