Application
High voltage cables are commonly used for applications such as interconnection between transmission lines, underground distribution systems and substations.
Feature
The construction of cables varies depending on the voltage level and the specific application.
For lower voltage levels, the cable consists of solid or stranded conductors with multiple layers of insulation and protective material added around them.
For higher voltage applications, additional layers of insulation and shielding are added to improve the electrical performance and safety of the cable.
