Abstract

Improvements in electrical cables, of the type having a plurality of conductors and a covering, characterized in that the interstices between the conductors and within the covering are at least partially filled with a mixture of hydrophobic powder and hydrophilic powder, forming the hydrophilic powder, on contact with water, a viscous material that does not settle.
