Abstract

A pig for installing a cable in a conduit, in which it comprises a body and a seal intended to follow the internal surface of the conduit, the body comprising a radially elastic tubular part on which the seal is mounted, and a support part fixed to or integral with the tubular part, the support part having a guide surface intended to guide the pig in the conduit, the diameter of the guide surface being slightly less than the maximum diameter of the seal, so that the support part radially deforms the tubular part when the pig passes through deformed parts of the conduit.
