Marine waterproof cable

Abstract

The invention discloses a marine waterproof cable, which comprises a regular pentagon rubber column body, wherein a crescent-shaped through hole is formed in the center of the regular pentagon rubber column body; five round holes are formed in the periphery of the crescent-shaped through hole; a wire core is arranged in each round hole and comprises a conductor; each conductor is formed by twisting a tinned copper wire bundle; a crosslinked polyethylene insulating layer, an aluminum magnesium alloy wire braided shielding layer and a waterproof canvas wrapping layer sequentially coat the outer side of each conductor; and a nano-silicon waterproof glue filling layer I, a polyester film wrapping layer, a nano-silicon waterproof glue filling layer II, an aluminum strip interlocking armor layer and a chlorosulfonated polyethylene outer sheath sequentially coat the outer side of the regular pentagon rubber column body. The crescent-shaped through hole is formed in the center to play buffering and compression resistance roles; the conductors are put into the round holes in the regular pentagon rubber column body; the structure is compact and firm; and by a multi-layer waterproofing material and a tensile structure, the marine waterproof cable has the advantages of being simple in structure, reasonable in design, economical, practical, safe and reliable.

Description

technical field [0001] The invention relates to the field of circuit technology, in particular to a marine waterproof cable. Background technique [0002] Marine cables have higher requirements on the tensile, compressive and waterproof properties of the cables, while ordinary marine cables are difficult to maintain intact in complex ship operating environments, with poor waterproof effects, short service life, and affect signal transmission. Contents of the invention [0003] The object of the present invention is to provide a marine waterproof cable in order to remedy the defects of the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A marine waterproof cable includes a regular pentagonal rubber cylinder, a meniscus-shaped through hole is opened in the center of the regular pentagonal rubber cylinder, and five circular holes are opened around the meniscus-shaped through hole. A wire core is placed in each circul...
