Abstract: A sealing member is provided which can be spirally wrapped around an elongate article (e.g., a cable) comprises a strip of sealing material (e.g., gel sealing material), and at least one series of gripping elements situated adjacent to the strip of sealing material and extending beside a longitudinal edge of the sealing material. In use, the gripping elements cause the sealing member to grip an elongate article around which it is spirally wrapped. The sealing member may also include a support strip to which the strip of sealing material and each series of gripping elements are attached.

Abstract: A retention strip for winding around an elongate object is disclosed. When the strip is wound in use it can decrease in length when compressed around the object, thereby contracting around the object. The strip preferably includes one or more, preferably a plurality of, collapsible portions, and the strip can decrease in length due to the collapsing of one or more of the collapsible portions.

Abstract: Flashover protection covers are provided in a continuous length for covering power line spans between supporting structures. A flexible panel includes an inner surface and generally parallel opposite edge portions configured to be joined together to form a first longitudinally extending chamber. A longitudinally extending first wall is connected along an edge portion thereof to the inner surface of the panel. The first wall has an opposite free edge portion and is configured to form a second longitudinally extending chamber within the first chamber. The second longitudinally extending chamber is configured to enclose a power line when the panel edge portions are joined together. A second wall is connected along an edge portion thereof to the inner surface of the panel and is configured to inhibit electrical arcing from the power line into the first chamber between the first wall free edge portion and the panel inner surface.
