Description

Technical Field

[0001] The utility model relates to the field of electric wires and cables, in particular to an insulating adhesive reinforced electric wire and cable. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and achieve electromagnetic energy conversion. In a broad sense, wires and cables are also referred to as cables. In a narrower sense, cables refer to insulated cables, which can be defined as a collection of the following components: one or more insulated wire cores, and their respective coatings, protective layers, and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] Known Chinese publicly authorized patents: (publication number: CN202120709708.X) disclose a wire and cable, which belongs to the field of mechanical technology. It solves the problem that existing cables are inconvenient to connect with gas supply equipment. This wire and cable includes a conductor, a sheath, and a plurality of hollow tubes sandwiched between the conductor and the sheath. The sheath is made of resin, and a partition is integrally formed in one end of the sheath. The partition divides the inner cavity of the sheath into non-connected cavity one and cavity two. Cavity one and cavity two are distributed along the length direction of the conductor, and the conductor and the hollow tube are both located in cavity two; the end face of the hollow tube close to the partition is attached to the partition and forms a seal. The partition is provided with a through hole that passes through the length direction of the conductor. The number of the through holes is the same as that of the hollow tubes and the positions correspond one to one. Each through hole is connected to the corresponding hollow tube. This wire and cable is easy to connect to the gas supply equipment.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned wire and cable had the following problems: the existing wire and cable reinforcement function was not effective, and the wire and cable were easily mechanically damaged, thereby shortening the service life of the wire and cable and increasing the frequency of replacement and maintenance. Therefore, an insulating glue reinforced wire and cable was proposed. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes an insulating glue reinforced wire and cable to solve the problem that the reinforcement function of the above-mentioned existing wires and cables is not effective, and the wires and cables are easily damaged by mechanical means, thereby shortening the service life of the wires and cables and increasing the frequency of replacement and maintenance.

[0006] To achieve the above-mentioned purpose, the utility model provides an insulating adhesive reinforced wire and cable, comprising:

[0007] PVC pipe;

[0008] Multiple conductors are arranged inside the PVC tube, the outer walls of the multiple conductors are provided with a first cross-linked polyethylene, the space between the multiple conductors is filled with a polyethylene filler, the outer walls of the multiple conductors are provided with a second cross-linked polyethylene, the outer walls of the second cross-linked polyethylene are provided with a steel wire braided mesh, and the outer walls of the steel wire braided mesh are provided with a semi-conductive shielding layer;

[0009] The outer side wall of the PVC pipe is provided with a protection mechanism.

[0010] Furthermore, the protection mechanism includes an anti-corrosion layer coated on the outer side wall of the PVC pipe, and the anti-corrosion layer is specifically made of epoxy resin.

[0011] Furthermore, the outer side wall of the anti-corrosion layer away from the PVC pipe is coated with a wear-resistant layer, and the wear-resistant layer is specifically made of polyurethane.

[0012] Furthermore, an outer side wall of the wear-resistant layer away from the PVC pipe is coated with an anti-ultraviolet layer, and the anti-ultraviolet layer is specifically a fluorocarbon coating.

[0013] Furthermore, a support column is provided at the center of the PVC tube, and the material of the support column is natural rubber.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The first cross-linked polyethylene is used to increase the mechanical strength and wear resistance of a single conductor, which can resist external mechanical damage, and the second cross-linked polyethylene is used to further increase the mechanical strength and wear resistance of multiple conductors. The polyethylene filler can effectively prevent moisture from entering the conductor radially and flowing longitudinally, ensuring that in the event of damage to the sheath, moisture cannot enter the conductor, thereby ensuring the reliability of communication and the service life of the cable. The steel wire braided mesh can further increase the mechanical strength and wear resistance, thereby effectively increasing the reinforcement function of the wires and cables, extending the service life of the wires and cables, and reducing the frequency of replacement and maintenance.

[0016] In order to better understand and implement the present invention, the present invention is described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
