Overhead cables are the base of the development of every industrialised country. As a part of the complex network, they are a type of a circulatory system supplying customers, from large industrial plants to a single household, with the electrical energy they need. The ability to provide the required energy supply influences economic development and societal progress on the one hand, and the quality of life of every citizen on the other. Therefore, the strategic aim of every developing country is the continuous development of the energy transmission and distribution network, an important part of which involves overhead cables.
On account of the application, structure and type of the production materials, overhead cables can be classified into three basic groups:
- bare cables to supply and distribute energy
- insulated cables to distribute energy
- cables for a railway traction
