Abstract
Cavo elettrico per alte ed altissime tensioni comprendente una pluralità di conduttori, almeno uno strato semiconduttivo, un isolante stratificato impregnato di un fluido isolante ed una guaina metallica esterna, in cui detto isolante è costituito da un laminato carta/polipropilene/carta, in cui polipropilene ha subito un trattamento tale da consentire a detto laminato di rigonfiarsi meno del 5% dopo immersione in decilbenzene a 100°C per almeno 3 giorni.(Fig. 1).
