Abstract

The invention discloses a damp-proof and anti-corrosion power cable for ships. The damp-proof and anti-corrosion power cable for ships is composed of conductors, a polyvinyl chloride insulating layer, a semiconductor shielding layer and an outer sheath, wherein the conductors are wrapped in the polyvinyl chloride insulating layer, four or more drainage cores are arranged among the conductors, and the drainage cores and the conductors jointly form a cable core. Filler is arranged in the intervals of the cable core and the polyvinyl chloride insulating layer, the semiconductor shielding layer is extruded outside the polyvinyl chloride insulating layer, and the semiconductor shielding layer is formed by tightly extruding the outer sheath, a stainless steel wire braided armor anti-corrosion layer and a water-stop taped covering from outside to inside. The damp-proof and anti-corrosion power cable for ships has good insulating performance, oxidation resistance and waterproof performance, is high in electricity conductivity, is good in corrosion resistance and is widely applied to the fields of ships, tunnels and the like.

Description

A kind of moistureproof corrosion-resistant ship power cable

Technical field

The present invention relates to field of cables, relate in particular to a kind of moistureproof corrosion-resistant ship power cable.

Background technology

At present, at present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as at boats and ships, the cable of the use fields such as tunnel in, to the anti-oxidation water resistance of cable, conductance, the requirement of diamagnetic jamming performance aspect is all high especially, and traditional cable is not because the reasons such as material have these functions, use this cable in special field, tend to cause irrecoverable loss.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of moistureproof corrosion-resistant ship power cable.

The present invention takes following technical scheme to realize: a kind of moistureproof corrosion-resistant ship power cable, it is to be made up of conductor, polyvinyl chloride insulation layer, shield semiconductors layer and oversheath, it is characterized in that: described conductor is wrapped up by polyvinyl chloride insulation layer outward; Between described conductor, be provided with more than four or four guide core; Described guide core and conductor form cable core jointly; The gap location of described cable core and polyvinyl chloride insulation layer is provided with filler; Described polyvinyl chloride insulation layer is extruded with shield semiconductors layer outward; Described shield semiconductors layer ecto-entad is that oversheath, stainless steel wire braiding armouring anticorrosioning sheath and the lapping layer that blocks water closely extrude and form; Described conductor is by stranded the forming of multiply silver-plated copper core; The packing that blocks water that in the described lapping layer that blocks water is many moulding forms jointly; The stainless steel wire count of described stainless steel wire braiding armouring anticorrosioning sheath is no less than 90%; The material of described oversheath is neoprene; Described filler is that water proof rubber is made.

The present invention has following beneficial effect in sum: this cable has good insulation property, anti-oxidation water resistance, and conductance is high, and excellent corrosion is widely used in the field such as boats and ships, tunnel.
