Abstract: A method of using a down-hole cable apparatus includes placing the down-hole cable apparatus in an operational position. The down-hole cable apparatus includes a metal tube, at least one conductor positioned within the metal tube, an armor shell positioned exterior of the metal tube and the at least one conductor, and a polymer material abutting the metal tube. The polymer material has at least one additive andremains substantially inert during a recrystallization process. The down-hole cable apparatus is subjected to an operational catalyst, during which time the polymer material having the at least one additive remains substantially inert. The inertia prevents linear separation of at least one of the at least one conductor and the armor shell from the metal.

Abstract: A stress control article for protecting joints and terminations in electrical power cables and for controlling electrical stresses, comprises a cover layer comprised of an electrically insulating, flexible polymeric material; and a stress control layer applied to one side of the cover layer. The stress control layer comprises a stress control material which may comprise a particulate filler comprising varistor particles; and a polymer matrix in which the particulate filler is embedded. The polymer matrix may comprise a silicone gum.

Abstract: A re-enterable end cap for sealing and protecting an end of an exposed cable conductor while allowing repeated access to the cable by a metal test probe. The end cap has an outer tubular shell which is open at one end to receive the end of the cable and closed at the opposite end by a plug of rigid material. The tubular shell may be dimensionally recoverable. The plug has a hollow cavity which contains a deformable self-sealing material. Access to the interior of the end cap is provided through an aperture in an end wall of the plug. The hollow interior of the plug may be provided with a one-way valve member which permits the test probe to enter the plug while preventing excessive loss of the self-sealing material through the aperture in the end wall. The valve member may take the form of a ball having a diameter which is greater than the diameter of the aperture and which is embedded in the self-sealing material.

Abstract: A fibrous closure comprises a dimensionally stable, heat resistant fibrous backing layer and a layer of high shear strength pressure sensitive adhesive. The closure is used in conjunction with a heat shrinkable, wraparound sleeve for sealing cable jackets, connectors and joints between lengths of pipe or other elongate objects. The sleeve is wrapped around the object such that its ends overlap. The closure is then applied over the overlapping ends of the sleeve to prevent slippage of the overlapping ends during heat shrinking, and to prevent subsequent creeping of the overlap joint due to hoop stresses in the shrunken sleeve. The closure avoids use of a relatively inflexible polymeric backing layer, and is therefore able to conform to objects having a relatively small diameter or irregular shape.

Abstract: An electrical crimp connector comprises a metallic crimp barrel adapted to receive the bared end portion of an electrical conductor and a heat-shrinkable polymeric sleeve in which the crimp barrel is received. The insulating sleeve is comprised of an ionic polymer derived from the polymerization of an &agr;-olefin and an ethylenically unsaturated carboxylic acid, a proportion of whose acid groups have been reacted to create ionic carboxylates of metal ions. The ionic polymer sleeve has high impact toughness, high abrasion and chemical resistance, high resistance to splitting by crimping tools, high degrees of flexibility and transparency, and a relatively low heat shrink temperature, making it more suitable for use in such connectors than sleeves comprised of other materials such as polyamides or polyolefins.
