A composite overhead cable with anti-extrusion and insect-repelling functions

Abstract

The invention provides a composite overhead cable with anti-extrusion and insect-repelling functions, relates to the technical field of power transmission lines, and solves the problem that when birds fall on the cable, it is easy to cause a fire under the action of electric incineration, and cannot The bird repelling effect is achieved by reducing the ability of birds to grasp the outer layer of the cable through structural improvement; too tight a clamp can easily lead to damage to the outer skin of the cable, which in turn accelerates the rate of corrosion and damage of the cable. A composite overhead cable with anti-extrusion and insect-repelling functions includes a cable main body; four cable main bodies are provided in total, and a waterproof layer is sleeved on the outside of the four cable main bodies. Because the elastic part is a coil spring, and the outer diameter of the elastic part is equal to the outer diameter of the protrusion B, and the elastic part forms the supporting structure when the device is locked, it can prevent the device from being damaged due to the locking force when the device is locked. Excessive size will cause the inner cable body to be crushed and damaged.

Description

technical field [0001] The invention belongs to the technical field of power transmission lines, and more specifically relates to a composite overhead cable with the functions of anti-extrusion and repelling insects. Background technique [0002] Aerial cables are overhead wires equipped with insulating layers and protective sheaths. They are made of a special cable similar to the production process of cross-linked cables. They are a new power transmission method between overhead wires and underground cables. [0003] For example, the application number: CN201710608024.9, this application discloses an overhead cable, including a plurality of cabled transmission lines and a single steel core, the steel core is arranged at the center of the overhead cable line, and the transmission lines are arranged Around the steel core, the steel core and the transmission line resist each other, and the two adjacent transmission lines resist each other. When the overhead cable is cabled, a ...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a composite overhead cable with anti-extrusion and insect repellent functions to solve the problem that the existing device does not have the ability to repel insects, when birds land on the cable It is easy to cause a fire under the burning action of electric power, and it is impossible to reduce the ability of birds to grab the outer layer of the cable through structural improvement to realize the bird repelling effect; moreover, when the existing device is fixed, if the card If the hoop is too tight, it is easy to cause damage to the outer sheath of the cable, which in turn accelerates the rate of corrosion and damage of the cable.
