Abstract
Cross-linked polyethylene is now being used for cables of higher and higher voltage. However, cross-linked polyethylene cables must have a considerable thickness of insulation, and efforts have been made to reduce it as far as possible. Research to attain further improvement in this respect has led to success in the development of a new type of power cable. This new type of cable is made by extruding cross-linked polyethylene over a stranded or hollow conductor and has a specially selected liquid between the conductor and the insulation at all times. It is a cable having an excellent voltage stability. In this report are mentioned various fundamental data obtained in the course of the development of such a liquid-filled type cross-linked polyethylene cable and the characteristics of this cable.
