CABLE SEALING

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.
