Abstract:
    A water blocking thixotropic hydrophobic compound for cables comprises a synthetic coil or a mixture of synthetic and mineral oils thickened to a gel by the addition of hydrophobic silica and/or bentonite. The gel properties of the compound may be temporarily removed by mechanical shearing to allow filling of the cable which may be a telecommunication, e.g. optical fibre, cable. An apparatus for cable filling is also described.
