not often used in transmission circuits because of the difficulty in insulating such high voltage wire. Because of the proven reliability benefits of insulated aerial cables over traditional air-insulated wire, the
Electric Power Institute has been working with utility companies to develop better insulating materials. In 1996 they were able to successfully convert one lower-voltage transmission circuit to insulated cable.

Aerial cables are usually freely hanging. However the former German power company EVS used for their internal communication network communication cables that were fixed like a garland on the ground conductor or on an auxiliary rope. Although the fact, that EVS is today part of EnBW and that beginning

Aerial cables are mostly used for telecommunication systems or for power transmissions with voltages below 1000 volts. Aerial cable for voltages up to 69,000 volts has also been built, for the supply of farms, waterworks, transmitters and other facilities outside of urban areas. Aerial cables are
