Abstract
The utility model discloses a shipboard power cable with inner and outer flame-retardant polyvinyl sheaths, which comprises conductor cores. Each of the conductor cores consists of a copper conductor, a cross-linked polyethylene insulating cover, and the conductor cores are covered with a lapping belt, the inner polyvinyl chloride sheath, a steel wire braided armored layer, the outer polyvinyl chloride sheath and an anticorrosion layer. The shipboard power cable with the inner and outer flame-retardant polyvinyl chloride sheaths is simple in structure and easy to implement. The inner and outer polyvinyl chloride sheaths outside the conductor cores can effectively improve flame retardant capacity of the power cable and also enhances safety thereof. The anticorrosion layer outside the conductor cores strengthens corrosion resistance of the power cable.
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 flame-proof polyvinyl chloride.
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 flame-proof polyvinyl chloride, 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 flame-proof polyvinyl chloride, 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, polyvinyl chloride oversheath, anti-corrosion layer successively.The inside and outside sheath ship power cable of described flame-proof polyvinyl chloride is characterized in that: described copper conductor surface is coated with the tin layer.
The inside and outside sheath ship power cable of described flame-proof polyvinyl chloride 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 polyvinyl chloride oversheath can improve power cable effectively, also improved the fail safe of power cable, the outer anti-corrosion layer of conductor thread core has strengthened the erosion-resisting ability of power cable.
