A method utilizes a funnel system and robotic end effector grippers to feed an unjacketed portion of a shielded cable through a sleeve. The funnel is designed with one or more thin extensions (hereinafter “prongs”) on which a sleeve is placed prior to a cable entering the funnel. Preferably two or more prongs are employed, although a single prong may be used if properly configured to both guide a cable and fit between the sleeve and cable. The prongs close off the uneven surface internal to a sleeve and provide a smooth surface for the cable to slide along and through the sleeve, preventing any damage to the exposed shielding. The sleeve is picked up and held on the prongs using a robotic end effector. If the sleeve is a solder sleeve, the robotic end effector has grippers designed to make contact with the portions of the solder sleeve that are between the insulating rings and the central solder ring.

A shrinkable cable joint includes a joint insulating layer that surrounds a connection region configured to house two connected cable ends. A joint semiconductive layer surrounds the joint insulating layer. A joint screen layer surrounds the joint semiconductive layer. A joint sheath surrounds the joint screen layer. A capacitive voltage sensor is arranged between the joint screen layer and the joint semiconductive layer. The capacitive voltage sensor includes a sensor insulating layer having a first side and an opposite second side; a sensor electrode and a guard electrode arranged on the second side and directly contacting the joint semiconductive layer; and a sensor conductive layer arranged on the first side. The sensor conductive layer includes a first conductive layer portion in direct contact with the joint screen layer and electrically coupled to the guard electrode and a second conductive layer portion electrically coupled to the sensor electrode.

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.

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.

The present disclosure describes an electrical cable accessory system for covering an electrical cable and/or cable connection. The electrical cable accessory system includes a pre-expanded cable accessory unit and a time-temperature indicator associated with the pre-expanded cable accessory unit. The pre-expanded cable accessory unit includes a pre-expanded cable accessory formed of an elastomeric material and a removable holdout mounted within the elastomeric cable accessory, wherein the holdout is operative to maintain the elastomeric cable accessory in an expanded state and to permit the elastomeric cable accessory to elastically contract when the holdout is removed from the elastomeric cable accessory. The time-temperature indicator is configured to undergo a visible change in appearance in response to a cumulative heat exposure and signal to a viewer when the elastomeric material of the pre-expanded elastomeric cable accessory unit has experienced a threshold cumulative heat exposure. Methods including the same are also described herein.
