Abstract:
A durable coating composition which reduces ice adherence and minimizes ice accumulation includes a silicate binder, a silane-modified filler, a film forming lubricant, and a crosslinking agent. Articles and overhead conductors coated with such coating compositions are also disclosed.
Abstract:
A compositional kit for forming a composition includes a first composition and a second composition which are separate. The first composition includes a filler, a cross-linking agent and an emissivity agent; and the second composition includes a silicate binder. Methods for making a compositional kit and for making a coated overhead conductor are also provided.
Abstract:
Compositions including a filler, an emissivity agent, a crosslinking facilitator, and a metal silicate binder are disclosed. The compositions can be curable at ambient conditions. Methods of coating overhead conductor and power transmission line accessories with such coating compositions are also disclosed.
Abstract:
Articles including a conductive metal substrate and a protective coating on the metal substrate are provided. The protective coating is electro chemically deposited from an electrodeposition medium including a silicon alkoxide and quaternary ammonium compounds or quaternary phosphonium compounds. Methods of electro chemically depositing such protective coatings are also described herein.
Abstract:
Improved 8000-series aluminum alloys exhibiting improved creep resistance and stress relaxation resistance are disclosed and are useful to form wires. The improved 8000-series aluminum alloys include a rare earth element. The electrical conductivity of the aluminum alloy is substantially unaffected by the addition of the rare earth element.
Abstract:
Cables including a fire-retardant composition are disclosed. The fire-retardant compositions include an oxygen-containing base polymer, a primary filler, and an antimony-containing secondary filler. The primary filler can be a metal hydroxide. The fire-retardant composition can be halogen- free and exhibit an elongation at break of about 150% or more. The cable passes the UL 1581 VW-1 flame.
Abstract:
A coating composition includes a fluoroethylene vinyl ether copolymer, a cross-linking agent, and water. The coating composition reduces the operating temperature of an overhead conductor by at least about 5° C or more compared to a similar uncoated overhead conductor when the operating temperatures of each overhead conductor are measured at about 100° C or higher and the coating composition is substantially free of solvent. Methods for making a coating composition and for making a coated overhead conductor are also provided.
Abstract:
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.
Abstract:
The present invention relates to a surface modified overhead conductor with a coating that allows the conductor to operate at lower temperatures. The coating is an inorganic, non-white coating having durable heat and wet aging characteristics. The coating preferably contains a heat radiating agent with desirable properties, and an appropriate binder/suspension agent. In a preferred embodiment, the coating has L* value of less than 80, a heat emissivity of greater than or equal to 0.5, and/or a solar absorptivity coefficient of greater than 0.3.
Abstract:
A method of crosslinking a polyolefin resin with a silyl hydride crosslinking agent is disclosed. Crosslinkable compositions containing a polyolefin resin having about 0.9% to about 10% diene groups and a silyl hydride crosslinking agent are also disclosed.
