Abstract: A splice for a skin-effect effect heating cable. The splice includes a primary shim configured to be shrunk over part of an insulation layer of a first portion of the heating cable, a secondary shim configured to be shrunk part of the insulation layer of a second portion of the heating cable, a connector configured to electrically couple the first portion of the heating cable and the second portion of the heating cable, and an outer cold shrink tube configured to be shrunk over the primary shim, the secondary shim, and the connector.

Abstract: A control system and methods for a digital circuit breaker are provided. The system comprises a digital circuit breaker, an electric trace heater electrically connected to the digital circuit breaker, a temperature sensor, and a controller device in communication with the digital circuit breaker and the electric trace heater. The controller device includes a processor in communication with the temperature sensor, and the processor is configured to receive a temperature value from the temperature sensor, construct a time-current curve for the digital circuit breaker based on the temperature value, and transmit data representative of the time-current curve to the digital circuit breaker.

Abstract: A pre-expanded cover assembly unit for covering an electrical connection between first and second cables includes a cover assembly in a folded state including an elastomeric outer sleeve defining a cable passage to receive the electrical connection. The outer sleeve includes an intermediate section and first and second outer sections. The first outer section is folded at a first annular fold and is on the intermediate section and/or the second outer section. The cover assembly includes a first retention layer between the intermediate section and the first outer section. The cover assembly includes a first friction reducing layer between the first retention layer and the first outer section. The cover assembly unit includes a removable holdout mounted within the outer sleeve. The cover assembly is movable from a folded state to an unfolded state by sliding the first outer section in a first axial direction away from the intermediate section.

Abstract: A seal system for an oil-filled cable termination including a cable extending through each of a cable gland and a stress cone that is spaced apart from the cable gland. The seal system includes: a first oil seal layer surrounding the cable between the cable gland and the stress cone; a second oil seal layer overlapping and contacting the first oil seal layer; a first oil barrier layer overlapping and contacting an upper portion of the second oil seal layer; a second oil barrier layer overlapping and contacting a lower portion of the second oil seal layer, the second oil barrier layer spaced apart from the first oil barrier layer; and a heat shrinkable tube secured around the first and second oil barrier layers.

Abstract: An integral, unitary pre-expanded cover assembly unit for covering an electrical connection between first and second electrical cables each having a primary conductor and a sleeve defines a cable passage to receive the electrical connection and the primary conductors of the first and second cables. The outer sleeve surrounds the inner sleeve. The duct is neutral conductor includes a cover assembly and a removable holdout. The cover assembly includes an elastomeric inner sleeve, an elastomeric outer sleeve, and a duct. The inner interposed radially between the inner and outer sleeves. The duct defines a duct passage configured to receive at least one of the neutral conductors therethrough. The holdout is mounted within the inner sleeve. The holdout is operative to temporarily maintain the inner sleeve in an expanded state and the outer sleeve in an expanded state. The duct is flexible.

Abstract: Provided are devices, methods and systems. A cover system may include a unitary cold shrinkable, tubular, elastomeric cover sleeve defining a cover sleeve through passage that is configured to receive the electrical cable. The cover sleeve may include a first type of stress control element and a second type of stress control element that is different from the first type of stress control element. A holdout maintains the cover sleeve in an expanded state in which the cover sleeve is elastically expanded and when removed, permits the cover sleeve to radially contract to a contracted state about the electrical cable. The first type of stress control element includes a geometric stress cone that includes an electrically conductive and/or semiconductive portion that is configured to conductively engage a semiconductor layer of the electrical cable. The second type of stress control element includes a high-K stress relief element.
