Embodiment Construction

[0010] refer to figure 1 , figure 2 , image 3 Firstly, the conductor 1 is made: multiple strands of copper wires 24 coated with water-blocking oil paste 22 are stranded to form the central layer of the conductor 1, and then the central layer is covered with a semi-conductive resistance water tape layer 23, and then coated with multiple strands of resistive oil. The copper wire 24 of the water-oil paste 22 is coated on the outside of the semiconductive resistance water tape layer 23 of the central layer, and then coated with the outer semiconductive resistance water tape layer 25 to form the conductor 1 . Make optical fiber communication unit 7 again: outside the loose tube 17 made of stainless steel tube with optical fiber 16 and fiber paste 21 inside, cover the inner sheath 18 made of high-density polyethylene and the armored layer 19 made of phosphating steel wire successively 1. The outer sheath 20 made of high-density anti-corrosion polyethylene is made into the optica...

Abstract

A rated voltage of 35kv or below shallow sea wind farm photoelectrical transmission composite cable comprises a cable core provided with a lead and a water-blocking filling piece, a water-blocking belting layer, a plastic-aluminum composite band layer, an internal sheath, a wire armoring layer and an external sheath, wherein the cable core are externally coated with the water-blocking belting layer, the plastic-aluminum composite band layer, the internal sheath, the wire armoring layer and the external sheath in turn, the cable core is internally provided with a fiber optic communication unit, a steel-tape armoring layer is arranged between the external sheath and the wire armoring layer. The structure of the fiber optic communication unit is as follows: a fiber loose tube is externally coated with an internal sheathing layer, an armoring layer and an external sheathing layer in turn. A conductor of the lead adopts two-tier structure: a central layer conductor is formed by twisting multiple stranded brass wires coated with water-blocking balm, and then coats a central layer semiconductive water-blocking band layer; an external layer conductor is coated outside the central layer semiconductive water-blocking band layer by multiple stranded brass wires coated with water-blocking balm, and then coats an external layer semiconductive water-blocking band layer. The invention has the complex function of optical communication and power transmission, one cable has two uses, thereby saving cost and facilitating laying; in addition, the cable has high strength, excellent wear resistance, corrosion resistance and waterproof function, and can adapt to the requirement for subsea use in long term.

Description

technical field [0001] The invention relates to a cable, especially a composite cable with both optical communication function and power transmission function. Background technique [0002] The existing cables for shallow sea wind farms with a rated voltage of 35kv and below only have the function of power transmission as connecting cables between wind turbines and substations. In order to grasp the operating status of each wind power generating set, it is necessary to lay additional optical cables to transmit optical signals for monitoring. This not only increases the manufacturing cost but also increases the laying cost and laying difficulty. Moreover, the mechanical strength, wear resistance, corrosion resistance, waterproof performance and other aspects of the existing cables are difficult to meet the requirements of long-term use on the seabed. Contents of the invention [0003] The purpose of the present invention is to provide a composite function of optical commu...
