    摘要: Methods for providing a cable closure enclosing a cable splice include wrapping a flexible wrap including a gel layer and a flexible support layer around the cable splice with the gel layer adjacent the cable splice. The gel layer may have an adhesion-reducing substance applied on at least part of a surface of the gel layer facing away from the flexible support layer and a removable cover layer may be applied to a surface of the gel layer facing away from the flexible support layer on which the adhesion-reducing substance is not applied. The wrap is gathered into overlapping wrinkles around at least one longitudinal end of the cable splice without applying heat, other external energy source or catalytic agent to allow the gel layer to seal the at least one longitudinal end of the cable splice.

    摘要: A flexible wrap (10) for enclosing a cable splice (20) without external heating includes a gel layer (1) and a support layer (2). The wrap has sufficient flexibility to be manually gathered into wrinkles around the smaller parts of the cable-to-splice transition with the gel sealing the resulting enclosure. The support layer (2), which is preferably made of low density polyethylene, provides mechanical strength and facilitates the application of the wrap (10). A vapour barrier layer (3), preferably made of aluminium, may be applied on the support layer (2). A protective layer (4) may be applied on the vapour barrier layer (3). An adhesion-reducing substance (6) may be applied on at least part of the side of the gel layer (1) facing away from the support layer (2) to allow adjustment of the wrap (10) when applied on the cable splice (20). Elastic or rubber tape (11) maybe wound around the applied wrap (10) to compress the gel. A re-enterable closure having a long sealing length may be obtained.

    摘要: A device for forming a seal around an elongate member, such as a wire, is provided. A device includes a first housing part and a second housing part movably connected to the first part. Sealing material such as a gel is positioned in the first housing part and provides a surface onto which the elongate member may be placed. A first member is positioned in the second housing part so as to displace the elongate member substantially laterally into the sealing material on movement of the second housing part relative to the first housing part. A device for applying a force to the sealing material on relative movement of the housing parts is also provided.

    摘要: A device for environmental protection of an electrical component on a mount, e.g. a circuit board, includes: a first housing part; a second housing part which together with the first housing part provides a substantially closed housing; a mount (e.g. a circuit board) for an electrical component that may be movably secured with respect to the first housing part; and a sealing material positioned between the mount and a surface of the first housing part; such that the mount can be moved with respect to the first housing part to put the sealing material under compression. The device can also include a maintenance termination unit for a telecommunications network.
