Description

An accompanying tensile cable for smart energy

technical field

The utility model relates to a cable, in particular to an accompanying tensile cable for smart energy.

Background technique

Existing accompanying tensile cables are generally reinforced with steel wire ropes and fiber braids, and are generally multi-core cables. The structural connections are as follows: 1) An insulated steel wire rope is added in the middle of the cable, so that the cable can withstand a certain tension when it is laid and used. The cable is generally used under tension, mainly to bear tension. This cable has good tensile strength, but because it is reinforced by steel wire, it becomes hard as a whole, not soft, so it is not easy to be used in bending and disturbing occasions. 2) After the cable is cabled, the inner sheath is extruded, then fiber braided, and then the outer sheath is extruded, so that the cable can withstand a certain tension during laying and use, and also improves the tear resistance of the sheath. This cable is soft degree is relatively high. But in terms of technology, the production is difficult, it is not easy to squeeze the sheath, and the efficiency is low. The existing steel wire rope is reinforced and placed in the cable core. Although the tensile strength is good, the hardness of the cable is increased, and the softness and bendability are poor; fiber braiding, the main fiber is braided on the inner lining of the cable. Although the softness is good, the manufacturing process Complicated and costly.

Utility model content

The purpose of the utility model is to solve the above technical problems and provide a tensile accompanying cable for smart energy with simple structure, high tensile strength, and reduced manufacturing process and cable cost.

The technical solution to realize the purpose of this utility model is a kind of accompanying tensile cable for smart energy, which consists of a cable core, a tape and an outer sheath from the inside to the outside; The filling layer between the wire core and the wrapping tape; the insulated wire core includes a conductor and an insulation layer; the conductor is formed by twisting a plurality of copper wires and fiber bundles with the same number.

The structure of the conductor is as follows: one copper wire is paired with one fiber bundle, two pairs are twisted and then layered twisted.

The conductor has four layers, from inside to outside, there are one group of copper wires and fiber bundles, six groups of copper wires and fiber bundles, twelve groups of copper wires and fiber bundles, and eighteen groups of copper wires and fiber bundles.

Each group of copper wires and fiber bundles are arranged and twisted in parallel.

The fiber bundle is glass fiber or carbon fiber or aramid fiber or polypropylene fiber or nylon fiber.

Adopting the above-mentioned technical scheme, the utility model has the following beneficial effects: (1) the utility model replaces the steel wire reinforcing core and the fiber braiding layer with fibers, and is twisted together with copper wires one by one when bundled, which can save The extruded steel wire rope is added to the center of the cable or the inner liner that must be extruded when fiber braiding is used, which reduces the amount of sheath, the manufacturing process and the cost of the cable, and the cable has outstanding tensile strength and softness.

(2) The fiber bundles and copper wires of the utility model are arranged and twisted in parallel, and the number of fibers increases and decreases with the size of the conductor specification. Since the fibers and copper wires are arranged and twisted in parallel, the force is uniform, and compared with other Tensile cable, light weight.

(3) The utility model optimizes the cable structure, simplifies the production process, reduces the cost, accelerates the cable production efficiency, and improves the production quality. Due to the small size and light weight of the cable structure, it also brings great convenience to users in laying and transportation.

(4) The structure of the utility model is suitable for various occasions such as moving, winding, and pulling.
