A carbon nanotube dispersion liquid contains a carbon nanotube-containing composition, a dispersant with a weight-average molecular weight of 1,000 to 400,000, a volatile salt, and an aqueous solvent. The carbon nanotube dispersion liquid can maintain a high dispersion of carbon nanotubes even with a smaller amount of dispersant than conventionally used.

A sealing composition and a sealing method for a coated electric cable have excellent sealing performance even under conditions such as cooling-heating cycles or high temperature and humidity. The coated electric cable sealing composition is for sealing a core wires connection section formed by electrically connecting multiple core wires exposed from multiple coated electric wires, and features having a hardening time of 10 minutes or less at 130° C., and permeating to inside of the coated electric wires at a height of 5 mm or more at the time point of hardening while the exposed parts of the core wires including the core wires connection section and the boundary part between the coated parts and the exposed parts of the core wires are immersed perpendicularly in the coated electric cable sealing composition filled in a resin cap and the sealing composition is heated to be cured.

In wire processing systems and methods, a wire channel receives a wire. One or more fluid guides flow the fluid into the wire channel to move, along the wire, a component (e.g. a solder sleeve) positioned at least partially in the wire channel and coupled to the wire. Other features are also provided.

The present invention provides a composition for coating an overhead conductor comprising: a binder which comprises a solvent and silica, organically modified silica, titanium oxide, aluminium oxide, zirconium oxide, iron oxide or a combination thereof; and an anti-corrosion agent, wherein the anti-corrosion agent is selected from an inhibitor pigment; a sacrificial pigment; a superhydrophobic agent; and combinations thereof.

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 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 strand-block mastic, the conductor being surrounded by a polymeric cable insulation. The method including pre-injection of compressed gas into the conductor strands of the cable at a pressure less than the elastic limit of the cable insulation, and injection of a rejuvenation fluid into the conductor strands of the cable at a pressure less than the elastic limit of the cable insulation.

A metallic cable includes, in order from an inner side thereof, a plurality of coated conduction wires, a press winding tape, a laminated tape, and an outer jacket. The outer jacket is provided on an outer circumference of the laminated tape and such that it covers the outer circumference of the laminated tape. The outer jacket is made of polyethylene having a density greater than or equal to that of medium-density polyethylene (MDPE) (≥930 kg/m.sup.3), and more preferably made of high-density polyethylene (≥942 kg/m.sup.3). If polyethylene having a density that is equal to or greater than that of MDPE is used to form the outer jacket, the temperature that is appropriate for extruding MDPE approaches a bonding temperature range of the resin layer of the laminated tape. The resin layer and the metal layer can be bonded and joined together at an overlapped part, tightly enclosing a cable core.
