Abstract
A cable has a filling compound (CA1, CA2) containing a swelling powder and at least one additive substance. This additive substance is mixed with the swelling powder and lies between the particles of the swelling powder to provide good water accessibility to the individual particles of the swelling powder given an incursion of water throughout the cable interspaces.
