Offshore floating electric cable

Abstract

The invention belongs to the field of a cable, and particularly relates to an offshore floating electric cable. A reinforcing rib is arranged at the center of the cable; a floater is arranged outside the reinforcing rib; a third waterproof protection layer is arranged outside the floater; a sealing layer is arranged outside the third waterproof protection layer; two layers of uniformly and annularly arranged conductors are arranged outside the sealing layer; a second waterproof protection layer is arranged outside the two layers of the uniformly and annularly arranged conductors; a first thermoplastic vulcanized rubber insulating layer is arranged outside the second waterproof protection layer; a layer of uniformly and annularly arranged insulating cable cores are arranged outside the first thermoplastic vulcanized rubber insulating layer; each insulating cable core consists of a conductor and a second thermoplastic vulcanized rubber insulating layer outside the conductor; the first waterproof protection layer is arranged outside the insulating cable core; and a polyurethane jacket is arranged outside the first waterproof protection layer. The offshore floating electric cable provided by the invention can solve the problems of poor waterproof property, insufficient buoyancy and the like, and can be used on the sea.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a floating water power cable for use in the sea. Background technique [0002] For floating cables, in addition to meeting the general performance requirements of ordinary cables such as tensile and frequent bending, the key is that the cable must be able to float on the water. The current floating water cable generally includes a sheath, a conductor and a floating body. The conductor is located in the middle of the floating body and the sheath, arranged up and down. The conductor is generally a copper conductor, and the floating body is generally made of solid foam and other materials. The disadvantages are: the density of the copper conductor is high, and the buoyancy is limited. If the copper conductor is too small, it will affect the transmission performance of the cable; if the aluminum conductor is used, its mechanical strength is low, the toughness is poor, and it is easy to break; i...
