A type of underwater cable with a buoy

Abstract

The invention discloses an underwater cable with a buoy. The cable comprises a cable body, buoy connection lines, a cable coiler and buoy heads, wherein the cable body comprises a conductor, an insulating layer, an electric shielding layer, an inner protective layer, a reinforcing layer and an outer protective layer, a plurality of buoy connection lines are fixedly wound outside the cable body at equal distance, the buoy connection lines pass through the cable coiler and the other ends thereof are fixedly provided with the buoy heads, the cable coiler comprises an outer protective shell, intercommunicating holes, the cable coiler and a pin shaft hole, two ends of the outer protective shell are provided with the intercommunicating holes communicated with the interior, an inner circle center of the outer protective shell is rotatably connected with a cable winding roller through a rotating shaft, one end of the buoy connection line is wound on the cable winding roller through the intercommunicating hole, a plurality of buoys are fixedly connected in the middle of the cable body through the buoy connection lines, and the position of an underwater cable can be determined through the position of the buoy on the water surface, so that the position of the cable can be determined conveniently in maintenance.

Description

technical field [0001] The invention relates to the technical field of underwater cables, in particular to an underwater cable with a buoy. Background technique [0002] Underwater cables are mainly used in underwater electrical equipment to realize functions such as power transmission, signal control, information transmission and launch. The structure of the existing underwater cables with a rated voltage of 0.6 / 1kV and below is as follows: after the plastic conductor is twisted or twisted first, the plastic insulation is extruded, and the plastic sheath is extruded after the cable is wrapped or armored. become. Rubber cables generally use multi-strand bundles of thin copper wires, twisted into conductors (mostly the fifth soft copper conductor), extruded rubber insulation layer, vulcanized, multi-core twisted into cables, and then extruded to protect Set, vulcanized. [0003] The underwater cables in the prior art have the following problems: [0004] 1. The process of...
