Overhead insulated conductor, as an efficient and safe means of power transmission, plays a vital role in the construction of modern power grid. With its unique insulation design, this wire realizes the effective isolation of power in the transmission process, which not only significantly improves the safety of the power system, but also greatly reduces the power loss caused by external environmental factors. The overhead insulated wire is mainly composed of a conductive core wire, an insulating layer and an external protective layer, in which the conductive core wire is responsible for the transmission of electric energy, while the insulating layer acts as a key barrier, effectively preventing the direct contact between the current and the external environment and avoiding the occurrence of potential safety hazards such as leakage and short circuit.

In practical applications, overhead insulated conductors are erected in the air through supporting structures such as poles and towers, forming a huge power network covering a vast area and providing continuous power support for thousands of households. Its insulation properties enable the wire to withstand adverse weather conditions, such as rain, snow and frost and other natural factors of erosion, to ensure the continuity and stability of power transmission. At the same time, the insulation layer can effectively prevent the contact of birds, small animals and other organisms, reduce the power failure caused by animal activities, and improve the overall operation efficiency of the power grid.

In addition, overhead insulated conductors also have good corrosion resistance and weather resistance, and can operate stably for a long time under various complex environmental conditions, reducing maintenance costs and replacement frequency. The installation process is also relatively simple and fast, which can effectively shorten the construction period and improve the overall efficiency of power grid construction.

To sum up, overhead insulated conductor with its excellent insulation performance, stable transmission capacity, good environmental adaptability and convenient installation, has become an indispensable part of modern power grid construction. With the continuous progress of science and technology and the increasing demand for electricity, the application range of overhead insulated conductors will continue to expand, contributing to the construction of a safer, more efficient and green power transmission network.
