A reinforcement arrangement for use with the connections of cable spices of undersea power cables that transport of electrical energy is disclosed. Each power cable includes an inner conducting core of copper or aluminum with one or more concentric polymeric and metallic layers that constitute insulation, screens and covers. The reinforcement arrangement is applied to the splicing of two cables at the conducting cores of each power cable, called a conducting cores connection area. The reinforcement arrangement includes a body that is disposed radially on the conducting cores connection area and on over the adjacent area of the outside outer covering of the power cable. The body is joined to the outer part covering of the power cables through a mechanical attaching element. The invention also relates to a method used to apply the reinforcement arrangement to the junctions of two submarine cables.

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 inner elastomeric sleeve, an outer elastomeric sleeve, and a collapsible duct. The inner elastomeric sleeve defines a cable passage to receive the electrical connection and the primary conductors of the first and second cables. The outer elastomeric sleeve surrounds the inner sleeve. The collapsible duct is interposed radially between the inner and outer sleeves. The duct defines a neutral conductor passage configured to receive at least one of the neutral conductors therethrough. The duct is selectively collapsible from an initial open configuration to a collapsed configuration about the at least one neutral conductor.

A pre-expanded breakout boot assembly for protecting a cable joint, the cable joint including a trunk and a plurality of cables extending from the trunk, includes a breakout boot assembly and plurality of removable finger holdouts. The breakout boot assembly includes a cold-shrinkable, electrically insulative, elastomeric breakout boot and plurality of finger sealant layers of a conformable medium. The breakout boot includes a tubular main section having an interior surface defining a main passage, and a plurality of tubular fingers extending from an end of the main section, each of the fingers having an interior surface defining a finger interior passage. Each of the finger sealant layers is pre-mounted on the interior surface of a respective one of the fingers. The conformable medium is a flowable material. Each of the finger holdouts is mounted in the finger passage of a respective one of the fingers such that the finger holdout maintains the finger in an elastically radially expanded state, and the finger holdout is selectively removable from the finger to permit the finger to elastically radially contract. Each finger sealant layer is positioned and configured such that, when the pre-expanded cover 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 will be radially interposed between each of the interior surface of the finger and the cable extending through the finger.

A cold shrinkable terminal comprises a terminal body fixed to a cable joint disposed at an end of the cable and a composite void filling mastic. The cable joint includes a conductor core, an inner insulation layer disposed on the conductor core, and a conductive shielding layer disposed on the inner insulation layer. The composite void filling mastic covers an incision of the conductive shielding layer and includes a filling layer in contact with the cable joint and a separating layer disposed between the filling layer and the terminal body. The separating layer is made of a material different than the terminal body.

It is an object of the present invention to provide a heat-recoverable article which heat-shrinks in an appropriate temperature range, in which the occurrence of bloom and bleeding is small, and which has excellent resistance to copper-induced damage; and a wire splice and a wire harness each including the heat-recoverable article. A heat-recoverable article according to the present invention has a cylindrical shape and includes a base material layer, in which the base material layer contains an antioxidant and two or more polyolefin resins, the base material layer has one melting-point peak temperature, the melting-point peak temperature is 112 C. to 128 C., the heat of fusion of all of the resin components of the base material layer is 80 to 130 J/g, and the oxidation induction temperature of the base material layer is 265 C. to 280 C.

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 cover assembly for covering an elongate substrate includes a resilient, elastically expandable sleeve member and a holdout device. The sleeve member defines an axially extending inner sleeve passage. The holdout device includes a generally tubular, flexible bladder sleeve mounted in the inner sleeve passage. The bladder sleeve defines a cavity and a holdout passage to receive the elongate substrate. The cavity is inflated or inflatable with an inflation gas.

The invention comprises a reinforcement arrangement used on connections of submarine cables, consisting of a body made up of a material reinforced with fibres of great mechanical strength that are arranged in a radial manner on the connection area of the cable and on the adjacent area of the outside covering of the cable, joined to the outer part of said cable through a mechanical attaching element. The invention is applied as protective elements aimed at protecting connections of submarine cables for the purpose of carrying electrical energy and placed on the seabed, making these connections very strong and elastic, and therefore suitable for bearing the great mechanical stress and tensions that must be born underwater. Additionally, the invention comprises a method by which the reinforcement arrangement is applied to the connections of two submarine cables.
