摘要 |
<p>A high voltage electrical power cable (1) with a stranded central conductor (2) encircled by insulation (5), a metal tape (8), metal strips or metal wires following helical paths outwardly of the insulation and a water swellable material (9) at least between the adjacent edges of the tape, strips or wires. Preferably, the water swellable material is included with a polymeric material which is flowable at a temperature at least as low as 100 DEG C, the polymeric material has a 100 gram needle penetration value in the range from 50-100 tenths of a millimeter at 25 DEG C and the water swellable material has a particle size not greater than 200 microns.</p> |
