Abstract
A method of forming an end seal on a cable is provided. The method includes providing a curable sealant in a cavity formed in a boot, inserting an end of the cable in to the cavity with the boot extending about the exterior of the cable, forcing the cable in to the curable sealant whilst inhibiting the egress of curable sealant from the boot to force the curable sealant along the interior of the cable, curing the curable sealant to provide a stable load supporting layer of sealant within the cable, and applying a crimping ring to the boot in the area of the load supporting layer to secure the boot to the cable.

A method of forming an end seal on a cable comprising the steps of providing a curable sealant in a cavity formed in a boot;
- inserting an end of the cable in to the cavity with the boot extending about the exterior of the cable;
- forcing the cable in to the curable sealant whilst inhibiting the egress of curable sealant from the boot to force the curable sealant along the interior of the cable;
- curing the curable sealant to provide a stable load supporting layer of sealant within the cable;
- and applying a mechanical retainer to the boot in the area of the load supporting layer to secure the boot to the cable
A cable having an elongate body including a conductor, an exterior coating, and a porous layer between said core and said exterior coating;
- a boot secured to one end of said body to seal said one end of said cable, said boot having a cavity to receive said cable, a cured sealant within said cavity and extending along said porous layer between said conductor and said outer layer to provide a stable load supporting layer within said cable;
- and a mechanical fastener to secure said boot to said cable.
An assembly jig having a pair of jaws to grip a cable and a moveable support for a boot, said support being moveable toward said jaws to force said boot on to said cable.
