Abstract (en)
The dielectric of a high-voltage cable is of lapped tapes that comprise alkene polymer film (13) preferably laminated between two paper layers (14). The dielectric is impregnated with an insulating liquid that is a aryl alkane having two or more separate benzene rings and 1-6 aliphatic non-cyclic carbon atoms per benzene ring. The benzene rings (or two of them if there are more than two in the molecule) are separated by no more than two aliphatic carbon atoms. Some of the aliphatic carbon atoms may be in hydrocarbon substituents in the benzene rings.
