Intumescent grid

An intumescent mesh has a flexible grid with a plurality of strands that form a series of openings in the flexible grid, and an intumescent coating applied to the flexible grid. The intumescent coating is made of an expandable graphite and a polymer-based carrier as ingredients and having an activation temperature above which the intumescent coating swells. The grid is sized such that the intumescent coating permits airflow through the flexible grid until the intumescent coating is exposed to temperatures at or above the activation temperature, whereupon the intumescent coating swells to seal the openings and prevent air flow through the flexible grid.

Coated overhead conductor

A polymeric coating can be applied to an overhead conductor. The overhead conductor includes one or more conductive wires, and the polymeric coating layer surrounds the one or more conductive wires. The overhead conductor can operate at a lower temperature than a bare overhead conductor with no polymeric coating layer when tested in accordance with ANSI C119.4 method. Methods of applying a polymeric coating layer to an overhead conductor are also described herein.

METHOD OF APPLYING COATING LIQUID TO AN OPTICAL FIBER

A method of applying a coating liquid to an optical fiber is described. An optical fiber is drawn through a guide die into a pressurized coating chamber and through the pressurized coating chamber to a sizing die. The pressurized coating chamber contains a coating liquid. The method includes directing coating liquid in a direction transverse to the processing pathway of the optical fiber in the pressurized coating chamber. The transverse flow of coating liquid counteracts detrimental effects associated with gyres that form in the pressurized coating chamber during the draw process. Benefits of the transverse flow include removal of bubbles, reduction in the temperature of the gyre, improved wetting, homogenization of the properties of the coating liquid in the pressurized coating chamber, and stabilization of the meniscus.

Method for manufacturing tow prepreg

A tow prepreg manufacturing apparatus applies resin to an original tow of reinforcing fibers. The tow prepreg manufacturing apparatus includes an oiling roller, a scraper, a resin reservoir, a tube pump, and a controller. The oiling roller is supplied with resin while rotating at a predetermined rotation speed. The scraper adjusts the shape of the resin supplied onto the oiling roller. The resin reservoir supplies resin to the oiling roller. The tube pump discharges resin to the resin reservoir. The controller controls the tube pump so that the amount of resin held in the resin reservoir remains constant and controls the rotation speed of the oiling roller so that a resin content of a wound tow prepreg becomes equal to a target resin content.

SILANE FUNCTIONAL STABILIZERS FOR EXTENDING LONG-TERM ELECTRICAL POWER CABLE PERFORMANCE

Provided are methods for extending the life of in-service electrical cable having polymeric insulation, comprising injecting into the cable a dielectric gel formulation containing: (a) SiH endblocked polydiorganosiloxane (H(R.sub.2SiO).sub.x(R.sub.2Si)H); (b) polydiorganosiloxane endblocked with unsaturated carbon-carbon functionality; (c) hydrosilylation catalyst suitable to cure (a) and (b); and (d) at least one organoalkoxysilane functional additive (e.g., anti-oxidant-based alkoxysilane, voltage stabilizer-based alkoxysilane, hindered amine light stabilizer (HALS)-based alkoxylsilane, UV absorber-based alkoxysilane, etc.), wherein (a) and (b) are cured post-injection into a non-flowable gel, and wherein (d) diffuses into the insulation.
