Problems solved by technology
[0002] At present, with the development of society and economy, the amount of wire and cable is increasing rapidly, and the quality requirements of cables are also continuously improving, such as cables used in ships, tunnels and other fields, the anti-oxidation and waterproof performance of cables, conductivity, The requirements for anti-magnetic interference performance are particularly high. The cables in the traditional sense do not have these functions due to materials and other reasons. The use of such cables in special fields often causes irreparable losses.

Embodiment Construction
[0008] Such as figure 1 As shown, a moisture-proof and corrosion-resistant marine power cable is composed of a conductor 1, a polyvinyl chloride insulating layer 2, a semiconductor shielding layer 3 and an outer sheath 6. It is characterized in that: the conductor 1 is covered with polyvinyl chloride The insulation layer 2 is wrapped; four or more drainage cores 7 are arranged between the conductors 1; the drainage cores 7 and the conductors 1 together form a cable core; A filler 8 is provided; the polyvinyl chloride insulating layer 2 is extruded with a semiconductive shielding layer 3; the semiconductive shielding layer 3 is an outer sheath 6, a stainless steel wire braided armor anticorrosion protective layer 5 and a water blocking layer from outside to inside. The wrapping layer 4 is tightly extruded; the conductor 1 is formed by twisting multiple strands of silver-plated copper cores; the water-blocking wrapping layer 4 is composed of multiple formed water-blocking fillin...

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
technical field [0001] The invention relates to the field of cables, in particular to a moisture-proof and corrosion-resistant marine power cable. Background technique [0002] At present, with the development of society and economy, the amount of wire and cable is increasing rapidly, and the quality requirements of cables are also continuously improving, such as cables used in ships, tunnels and other fields, the anti-oxidation and waterproof performance of cables, conductivity, The requirements for anti-magnetic interference performance are particularly high. The cables in the traditional sense do not have these functions due to materials and other reasons. The use of such cables in special fields often causes irreparable losses. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a moisture-proof and corrosion-resistant marine power cable. [0004] The present invention ...
