摘要： A method for rejuvenating a strand-blocked cable having a conductor comprised of a plurality of conductor strands with interstitial volume therebetween blocked by a PIB based mastic, the conductor being surrounded by a polymeric cable insulation. The method comprising installing injection adapters that seal the cable ends of the cable and are usable to inject fluid into the interstitial volume between the conductor strands of the cable; elastically expanding the polymeric cable insulation through the application of pressure to the interstitial volume between the conductor strands of the cable; and injecting at least one injection fluid in which the PIB based mastic is mostly insoluble into the interstitial volume between the conductor strands of the cable.

摘要： A system including an active ventilation device and a system controller. The active ventilation device is installed in an underground vault and generates an exhaust flow from the vault having an exhaust rate. The system controller is configured to determine that a reading received from a selected gas sensor indicates that a manhole event is occurring, and instruct the active ventilation device to change the exhaust rate when the reading indicates that the manhole event is occurring. The system controller is configured to receive at least one sensor reading after the exhaust rate has been changed, determine whether the selected gas sensor is exhibiting drift based at least in part on the sensor reading(s), and perform an action when the system controller determines the selected gas sensor is not exhibiting drift. The action includes notifying a user and/or instructing the active ventilation device to alter the exhaust rate.

摘要： A method for extending the useful life of an in-service electrical cable section having at least two existing connectors attached thereto and a conductor surrounded by a conductor shield encased in a polymeric insulation jacket with an interstitial void volume in the region of the conductor. The method includes replacing each connector with a corresponding high-pressure connector, and injecting a dielectric enhancement fluid into the void volume and confining the fluid therein at a pressure sufficient to introduce at least about 0.75Q of the fluid. Wherein Q represents the weight of the fluid which would saturate the conductor shield and insulation jacket, and the void volume at atmospheric pressure being less than that which would accommodate the amount 0.75Q. The method is carried out using only a single switching cycle.

摘要： A high-pressure connector for an electrical power cable segment having a central stranded conductor encased in a polymeric insulation jacket with an interstitial void volume in the region of the conductor. The connector confines a fluid within the interstitial void volume at a residual pressure above atmospheric, but below the elastic limit of the insulation jacket. A housing interior chamber receives the conductor in fluid communication with the interstitial void volume. Some embodiments have the chamber sized to receive and overlap a portion of the insulation jacket with a housing end portion swaged thereto. A seal seals the insulation jacket with respect to the housing and a retaining member secures the cable segment to the housing to prevent pushback of the insulation jacket at the residual pressure.
