The role of overhead insulated conductors
Release time:
2023-03-10
Overhead insulated wire refers to the wire made of insulating material, twisted on the power overhead line with a certain distance, it is a safe and reliable way of power transmission, is an important means to achieve power transmission. On the basis of insulation technology, the view that insulated conductors can be placed in overhead power overhead lines is proposed, and such a design is realized, from which overhead insulated conductors are introduced into the power system.

On the basis of insulation technology, the view that insulated conductors can be placed in overhead power overhead lines is proposed, and such a design is realized, from which overhead insulated conductors are introduced into the power system.
With the development of science and technology, the development of overhead insulated wire is more and more rapid, its application is more and more widely, the security is also more and more high. At present, the overhead insulated wire has become an indispensable part of the power system, it can transmit a large amount of power in a short time, safe and reliable, so it is widely used in urban, industrial and rural power system.
Overhead insulated wire has a series of advantages. First, it can transmit a large amount of electric energy in a short time, and because of the use of insulating materials, it can avoid the loss of electromagnetic waves and greatly improve the transmission efficiency of electric energy. Secondly, it reduces electromagnetic interference on overhead lines and can effectively prevent fires. It is convenient to install and maintain, and it can also improve the seismic capacity of the project, these are the advantages of overhead insulated conductors.
In general, the safety and reliability of overhead insulated conductors are constantly improving, and it has become an important means to achieve power transmission. Its application is more and more extensive, and it has been widely recognized by people.
Before the installation of overhead insulated wires, it is necessary to make preparations for the wires, including checking whether the wires are damaged, checking the bracket model, checking whether the installation position of the bracket is correct, and whether the screws of the mounting bracket are tightened. Ensure that the installation environment of overhead insulated conductors is safe, and the insulated conductors have a protective space from the outside to avoid short circuits. Check whether the installation position of the bracket and anchor tower is correct, so as not to affect the installation of insulated wires.
Put one end of the insulated wire into the bracket from the anchor tower, and put the other end into the other anchor tower. Make sure that the bracket is tight and the wire is installed vertically. Fix the wire on the anchor tower with special screws, and tighten the screws with a wrench to ensure that the screws are not loose. Straighten the wire and pull it to the specified position to ensure that the tension is even to avoid breaking of the insulated wire. After the wire is installed, use a special measuring instrument to detect the resistance of the insulated wire to ensure that the installation of the insulated wire is completed.
Precautions
Contact of insulated conductors with other cables should be avoided to avoid electrical short circuits. Avoid pulling the insulated wire to a position greater than the specified pulling force to prevent the insulated wire from breaking. Attention should be paid to protection to avoid damage to insulated wires due to improper operation. Special screws must be used to ensure the installation quality of the wire. At the same time, it is necessary to ensure that the installation position of the bracket is correct, so as not to affect the installation effect and service life of the insulated wire.
