Abstract

Perfeccionamientos en la fabricación de cables eléctricos, caracterizados porque se dota a cada cable de un alma de una pluralidad de conductores aislados y una cubierta, rellenándose al menos parcialmente los intersticios entre los conductores y en el interior de la cubierta con una mezcla de carbonato cálcico tratado, hidrófugo, y por lo menos unas resina de elevado peso molecular rápidamente hidratable para formar una solución viscosa.
