In the field of power transmission, high-voltage cables are an indispensable component. The selection of insulation materials for high-voltage cables is crucial for power transmission. In this paper, we will focus on the common insulation materials and their characteristics of high-voltage cables, and analyze the advantages and disadvantages of different types of insulation materials by comparing and contrasting them, and make an in-depth analysis from the perspectives of material properties and applicable scenarios.

First, let's take a look at polyvinyl chloride insulated power cables. As a common insulating material, PVC has good heat resistance and corrosion resistance, and is suitable for power transmission under various environmental conditions. The nominal thickness of its insulation can also effectively prevent current leakage and improve the safety of the cable. However, PVC insulated power cables also have some disadvantages, such as easy deterioration in high temperature environments, and need to be replaced periodically to ensure the stability of power transmission.

In summary, the selection of insulation materials for high-voltage cables has an important impact on power transmission, and it is crucial to choose the right insulation materials for different scenarios. Only by choosing under a professional, objective and analytical perspective can we ensure the smooth progress of power transmission. We hope that this article can help you better understand the insulation materials of high-voltage cables and provide some reference for the development of the power transmission field.
