Abstract
Perfeccionamientos en la fabricación de cables de energía, particularmente para el tendido subacuático, de la clase de los que comprenden un asilamiento de papel impregnado con un aceite fluido, caracterizados esencialmente por el hecho de llevar a cabo la impregnación con un fluido que presenta una viscosidad inferior a 15 cSt a 20ºC y pérdida en el dieléctrico (tang delta) menor o igual que 0,001, en presencia de al menos un derivado alifático inferior de la naftalina, apto para fijar químicamente los gases que se desprenden del papel aislante y del fluido de impregnación por calentamiento y por envejecimiento del cable.
