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.

A fluid circulation device having at least one fluid circulation tube, a first coupling sealingly coupled to a first end of the tube and a second coupling sealingly coupled to a second end of the tube in such a way as to allow the circulation of fluid between said two couplings via the tube. The device further has separate electronic elements. The tube has at least one conductor track extending along an outer surface of the tube. The track is suitable for transmitting at least one signal and arranged to engage with the abovementioned electronic elements.

A gas resistant pothead system and method for electric submersible motors. A gas resistant pothead system includes a lead foil wrapped motor lead cable (MLE) extending through a pothead, a sleeve of an insulator block inside the pothead, the sleeve including gold plating and lead-foil wrapping over the gold plating, and a lead-to-gold seal formed between the gold plating of the sleeve and the lead foil wrapping over the gold plating. A method of creating a seal to gas around a power cable connection to a downhole electric submersible motor includes wrapping lead foil around a MLE extending through a pothead, continuing the lead foil wrapping around a gold-plated sleeve of an insulating block inside the pothead, mechanically reinforcing the lead foil with an encapsulant, and bonding the lead foil to the gold plating of the insulating block.

Disclosed is a crosslinked polyethylene resin composition. According to the present disclosure, a crosslinked polyethylene resin composition having general allowance temperature due to excellent heat resistance characteristics, enhanced long-term workability due to superior long-term aging resistance, and water tree inhibition effects similar or better than those of conventional crosslinked polyethylene (XLPE)), and a power cable manufactured from the composition may be provided.

Disclosed herein is a hydrophobic cable, particularly a cable for medical devices having a hydrophobic surface. The hydrophobic cable includes a conductive unit arranged in a longitudinal direction of the cable, an insulating sheath coated onto an outer portion of the conductive unit and made of a PVC material, and a coating film formed outside the insulating sheath. Here, the coating film may be formed by curing a coating solution including at least one monomer selected from the group consisting of a silane compound and a siloxane compound.

Provided is an ATF (Automatic Transmission Fluid) oil and corona-resistant enameled wire for electric vehicle motors, belonging to the insulating materials field. The ATF oil and corona-resistant enameled wire for electric vehicle motors comprises a copper conductor and an insulating layer, wherein said insulating layer from inside to outside is composed of ATF oil and corona-resistant protective film, corona-resistant PAI film, ATF oil and corona-resistant protective film, corona-resistant PAI film, ATF oil and corona-resistant protective film. The ATF oil and corona resistant enameled wire of this disclosure is suitable for the preparation of oil-cooled electric vehicle motor loose winding coil due to the advantages of good manufacturability, excellent ATF oil and corona resistance, and low manufacturing cost.

A fitting for injecting a first fluid into an injection port of a cable accessory. The fitting includes at least one seal positioned on an injection nozzle. The nozzle is configured to be inserted into the port and has an internal fluid passageway through which the first fluid is injected into the accessory. The seal forms at least one fluid tight seal between the nozzle and the port. The fluid tight seal prevents the first fluid from exiting the accessory and flowing into an outer portion of the port and prevents a second fluid from flowing into an inner portion of the port. The first and second fluids have first and second voltage potentials, respectively. The second voltage potential is different from the first voltage potential. The seal isolates the first and second voltage potentials by isolating the first fluid from the second fluid.

A valve assembly that includes a valve body, a poppet member, and a biasing member. The valve body has an internal through-channel. The poppet member has an inside portion positioned at least partially inside the through-channel and an outside portion positioned outside the through-channel and extending outwardly beyond the valve body. The poppet member is movable within the through-channel between an open position and a closed position. The biasing member is external to the valve housing and applies a biasing force to the outside portion of the poppet member that biases the poppet member toward the closed position.

A high-pressure connector for use with a cable accessory having an injection port with an opening into an interior chamber defined by one or more sidewalls. The connector includes a body portion and one or more fluid seals. The body portion has an inner fluid chamber, an outer surface, and an aperture. The inner fluid chamber is configured to allow a conductor of a cable to pass therethrough. The fluid seal(s) are positionable between the outer surface of the body portion and the one or more sidewalls to define an outer fluid chamber. The outer fluid chamber is positioned such that the opening of the injection port is positioned within the outer fluid chamber so that a fluid exiting the injection port through the opening enters the outer fluid chamber. The aperture connects the outer and inner fluid chambers and allows the fluid to flow therebetween.
