Abstract
The utility model discloses a power cable for a ship with a flame-retardant polyvinyl chloride inner jacket and a polyolefin outer jacket. The power cable comprises conductor cores, wherein each conductor core consists of copper conductors and a cross-linked polyethylene insulating sleeve; the conductor cores are coated with a tape, the polyvinyl chloride inner jacket, a steel wire woven armor layer and the polyolefin outer jacket; and filling materials are arranged between the conductor cores and the tape. The power cable has a simple structure, and is easy to realize; by adopting the polyvinyl chloride inner jacket and the polyolefin 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 filling materials, the intensity of the power cable is enhanced.
Description
Technical field
The utility model relates to the power cable field, is specially a kind of flame-proof polyvinyl chloride inner sheath, polyolefin 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 flame-proof polyvinyl chloride inner sheath, polyolefin 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:
Flame-proof polyvinyl chloride inner sheath, polyolefin oversheath ship power cable, 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, polyvinyl chloride inner sheath, braided steel wire armour, polyolefin oversheath successively, and the space between described conductor thread core and the twining package tape is filled with filler.Described flame-proof polyvinyl chloride inner sheath, polyolefin oversheath ship power cable is characterized in that: described copper conductor surface is coated with the tin layer.
Described flame-proof polyvinyl chloride inner sheath, polyolefin 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, 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, polyvinyl chloride inner sheath outside the conductor thread core, the fire retardancy that the polyolefin oversheath can improve power cable effectively, also improved the fail safe of power cable, the filler in space has strengthened the intensity of power cable effectively between conductor thread core and the twining package tape.
