Embodiment 1

[0042] See figure 1 , the aluminum-clad composite core wire cable of the present invention includes 7 or 19 or 37 aluminum-clad composite core wires 1, and the 7 aluminum-clad composite core wires 1 are normally twisted into a composite core wire cable with a 1+6 structure; 19 aluminum-coated composite core conductors 1 adopt a 1+6+12 structure to form a composite core conductor cable; 37 aluminum-coated composite core conductors 1 adopt a 1+6+12+18 structure to form a composite core conductor cable. The pitch diameter ratio of the stranded cable is 10 to 30, and the pitch diameter ratio of the outer layer is not greater than the pitch diameter ratio of the inner layer.

[0043] The aluminum-clad composite core wire cable in this embodiment is composed of seven composite core wires 1 that are normally stranded in a 1+6 structure. The aluminum clad composite core wire 1 includes a wire core 1-1 and an aluminum cladding layer 1-2. The diameter of the wire core 1-1 is 1.0 to 5....

Embodiment 2

[0047] See figure 2 and image 3 , the rest of this embodiment is the same as that of Embodiment 1, the difference is that: an adhesive layer 1-3 is also included. The matrix of the wire core 1-1 is made of thermosetting resin such as phenolic resin, unsaturated polyester, epoxy resin or thermoplastic resin such as polyphenylene sulfide.

[0048] Adhesive layer 1-3 is made of polyether ether ketone resin material, polyether ether ketone resin is coated on the outside of wire core 1-1 by extrusion process, aluminum cladding layer 1-2 is coated on adhesive layer 1-3 The outside is in direct contact with the adhesive layer 1-3 to form an adhesive fixed connection. The thickness of the adhesive layer 1-3 is 0.2 mm to 1.0 mm.

Embodiment 3

[0050] The rest of this embodiment is the same as that of Embodiment 2, except that the adhesive layer 1-3 is made by using continuous fiber as a reinforcement and polyether ether ketone resin as a matrix through a thermoplastic pultrusion process. The fiber body adopts continuous fibers such as carbon fiber, glass fiber, basalt fiber or aramid fiber.

Abstract

The invention discloses an aluminum-clad composite core wire cable. The aluminum-clad composite core wire cable comprises 7 or 19 or 37 aluminum-clad composite core wires, and the 7 aluminum-clad composite core wires are regularly stranded into a composite core wire cable by adopting a 1+6 structure. 19 aluminum-coated composite core wires are regularly twisted into a composite core wire cable byadopting a 1+6+12 structure. 37 aluminum-coated composite core wires are regularly twisted into a composite core wire cable by adopting a 1+6+12+18 structure. The cable is characterized in that the pitch diameter ratio of the twisted cable is 10-30, and the pitch diameter ratio of the outer layer is not greater than the pitch diameter ratio of the inner layer. Each aluminum-coated composite core wire comprises a wire core and an aluminum coating layer. The aluminum coating layer coats the outer portion of the wire core.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to an aluminum-clad composite core conductor cable and a production process thereof. Background technique [0002] Traditional transmission lines mostly use steel-cored aluminum stranded cables, which have disadvantages such as large line loss and low maximum allowable continuous operating temperature, so carbon fiber composite conductor cables have emerged as the times require. Compared with steel core aluminum stranded wire cables, carbon fiber composite wire cables have the advantages of light weight, high strength, high temperature resistance, corrosion resistance, low line loss and environmental affinity, and the transmission capacity can be doubled. However, the carbon fiber composite conductor cable is limited by the material itself. Compared with the steel core aluminum stranded wire cable, the bending diameter is larger. Accidents occur.
