Beschreibung
Zusammenfassung:	A high voltage electrical power cable with a longitudinally folded, smooth or corrugated, metal strip around a plurality of layers around the conductor and a water swellable material at least at the adjacent edges of the strip. Preferably, the water swellable material is included with a polymeric material which is flowable at a temperature at least as low as 100.degree.C, the polymeric material has a 100 gram needle penetration value in the range from 50-100 tenths of a millimeter at 25.degree.C and the water swellable material has a particle size not greater than 200 microns.
