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:
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.
Abstract:
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.

Abstract:
An aerial cable treatment system having a cable surface preparation assembly and a coating assembly. The cable treatment system is translatable along an in-situ aerial cable. The cable surface preparation assembly can remove dirt and debris, such as carbon deposit, grease, mud, fertilizers, bird droppings, fungal growth, mosses, soot, ice, and like from aerial cables with varying sizes as it translates along the cable. The coating assembly can apply a coating to the outer surface of the in-situ aerial cable it translates along the cable.
Abstract:
A conductive composition can include a polyolefin base polymer, a high structure carbon black and a low structure carbon black. The conductive composition can exhibit two or more of a thermal conductivity of about 0.27 W/mK or more when measured at about 75 °C, a volume resistivity of about 75 ohm-m or less when measured at about 90 °C and an elongation at break of about 300% or more. Cables having coverings formed of such conductive compositions and methods of making such cables are also described herein.
Abstract:
A cable includes an inner layer surrounding a conductor and an outer layer surrounding the inner layer, and the outer layer is formed from an extruded outer layer composition including an at least partially cross-linked resin including a base polyolefin and a weak acid source, an inorganic flame retardant, and one more of an organic char former and a spumific agent. The cable passes the Underwriters Laboratory ("UL") 1581 VW-1 Flame Spread Test and one or more of the UL 44 Long-Term Insulation Resistance Test at 90° C and the ceramifying requirements of International Electrotechnical Commission ("IEC") 60331-21. Methods of manufacturing such cables are also disclosed.
Abstract:
