A cold shrink article made from a composition comprising (A) an ethylene/-olefin interpolymer; (B) a filler; and (C) an ,-unsaturated carboxylic acid. The composition may optionally include additives selected from the group consisting of plasticizer, peroxide curing agent, antioxidant, process additives, flame retardant and combinations thereof.

A pre-expanded breakout boot assembly includes a breakout boot assembly including an elastomeric breakout boot and plurality of finger sealant layers of a flowable conformable medium. The breakout boot includes a tubular main section and a plurality of tubular fingers extending from an end of the main section. Each of the finger sealant layers is pre-mounted on an interior surface of a respective one of the fingers. Each of the finger holdouts is removably mounted in the finger passage of a respective one of the fingers. When the pre-expanded breakout boot assembly is positioned on the cable joint with a cable extending through each finger passage, the finger holdouts are removed from the breakout boot assembly, and each finger elastically radially contracts about a respective one of the cables, each finger sealant layer is radially interposed between each of the interior surface of the finger and the cable in the finger.

A cable jacket for a conductor is disclosed having a flame-retardant insulation and a gas-permeable, heat-resistant outer casing. The flame-retardant insulation is positioned over the conductor so as to at least partially surround the conductor. The gas-permeable, heat-resistant outer casing surrounds the flame-retardant insulation.

A variable diameter termination includes an elastomeric tubular housing having a first portion with a first inner diameter, a second portion with a second inner diameter, and a third portion disposed between the first portion and the second portion and with a transition inner diameter. The elastomeric tubular housing is disposed on a tubular core that includes a first portion with a third outer diameter, a second portion with a fourth outer diameter, and a third portion disposed between the first portion and the second portion and with a transition outer diameter. The first portion of the elastomeric tubular housing is disposed over the first portion of the tubular core, the second portion of the elastomeric tubular housing is disposed over the second portion of the tubular core, and the third portion of the elastomeric tubular housing is disposed over the third portion of the tubular core.

A cold shrink splice article is provided comprising a thermally conductive silicone rubber composition capable of exhibiting high thermal conductivity of >0.4 W/m*K, or >0.5 W/m*K and desirable mechanical properties including >500% elongation at break.

A sealing system for forming an environmentally sealed joint with an elongate member includes a tubular substrate, a pre-expanded cover unit, and a flowable sealant. The tubular substrate includes an integral guide feature and defines a substrate bore to receive a portion of the elongate member. The pre-expanded cover unit includes a holdout and a tubular cover sleeve. The holdout includes a helically wound strip forming a tubular holdout body and a rip cord. The holdout body defines a holdout passage extending axially therethrough. The tubular cover sleeve is mounted on the holdout body. The holdout maintains the cover sleeve in a radially elastically expanded state. With the elongate member positioned with a portion thereof extending from the tubular substrate and a layer of the sealant mounted on an outer surface of the tubular substrate and/or on an outer surface of the elongate member, the pre-expandable unit can be mounted around the layer of sealant and the holdout can then be removed from the cover sleeve by withdrawing the rip cord through the holdout passage between the layer of the sealant and the holdout body to remove the holdout body and thereby permit the cover sleeve to radially contract about the tubular substrate and the elongate member, and the guide feature serves to prevent or inhibit the rip cord from contacting the layer of the sealant as the rip cord is withdrawn through the holdout passage.

A cable termination including a cable terminal and a cable joint assembly. The cable terminal includes: a terminal conductor; a monitoring device including a capacitive voltage sensor around the terminal conductor; and an electrically insulating body fitted around the terminal conductor, including a bell-shaped end portion in which the voltage sensor is at least partially embedded. The cable terminal alternatively includes: a terminal conductor; a monitoring device including a capacitive voltage sensor around the terminal conductor; and an electrically insulating body fitted around the terminal conductor, including a bell-shaped end portion in which the voltage sensor is at least partially embedded and a stem end portion, the terminal conductor extending beyond the stem end portion.

A cold shrink article made from a composition comprising (A) an ethylene/-olefin interpolymer; (B) a filler; and (C) an ,-unsaturated carboxylic acid. The composition may optionally include additives selected from the group consisting of plasticizer, peroxide curing agent, antioxidant, process additives, flame retardant and combinations thereof.

An integral, unitary cover assembly for covering an electrical connection between first and second electrical cables each having a primary conductor and a neutral conductor, includes an elastomeric inner sleeve, an elastomeric outer sleeve surrounding the inner sleeve, and a collapsible duct assembly interposed radially between the inner and outer sleeves. The inner sleeve defines a cable passage to receive the electrical connection and the primary conductors of the first and second cables. The duct assembly includes an outer duct sleeve member defining a first passage and an inner retention member disposed in the first passage. The retention member maintains the duct sleeve member in an open configuration when the retention member is disposed in the first passage. The duct sleeve member is selectively collapsible about the at least one neutral conductor from the open configuration to a collapsed configuration by withdrawing the retention member from the first passage.
