摘要:
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.
摘要:
A cable assembly includes a conductor and a self-cleaning layer that surrounds the conductor and includes one or more of a photocatalyst and an electrocatalyst. Overhead high voltage electricity transmission lines are formed from these cable assemblies. Methods of reducing surface buildup on a cable are also provided.
摘要:
A coated overhead conductor having an assembly including one or more conductive wires, such that the assembly includes an outer surface coated with an electrochemical deposition coating forming an outer layer, wherein the electrochemical deposition coating includes a first metal oxide, such that the first metal oxide is not aluminum oxide. Methods for making the overhead conductor are also provided.

摘要:
A coated electrical accessory includes a bare electrical accessory and a substantially inorganic and dried coating layer coating the bare electrical accessory. The coating layer includes a heat radiating agent and a binder. When the coated electrical accessory is tested in accordance with ANSI CI 19.4-2004 with an amount of imparted current, the coated electrical accessory exhibits an operating temperature that is less than an operating temperature of a bare electrical accessory tested in accordance with ANSI CI 19.4-2004 with the same amount of imparted current. Methods are also provided.
摘要:
Articles including a conductive metal substrate and a protective coating on the metal substrate are provided. The protective coating is electrochemically deposited from an electrodeposition medium including a silicon alkoxide and quaternary ammonium compounds or quaternary phosphonium compounds. Methods of electrochemically depositing such protective coatings are also described herein.
摘要:
A thermoset composition can include a cross-linked polyolefin; a primary filler selected from the group consisting of talc, calcined clay, or combinations thereof; a secondary filler selected from one or more of a metal oxide and a metal nitride, and one of a composition stabilizer and antioxidant. The thermoset composition can exhibit a thermal conductivity of at least about 0.27 W/mK, and/or a dielectric loss tangent of less than about 3% when measured at 90° C. The thermoset composition can be used in the construction on an insulation layer or jacket layer of a power cable.
