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 durable coating composition includes a silicate binder, a filler, and a crosslinking agent. The coating composition can reduce ice adherence and minimize ice accumulation through inclusion of a film forming lubricant. Articles and overhead conductors coated with such coating compositions are also disclosed.
Abstract:
A cable separator comprising a preshaped article having a longitudinal length, wherein said preshaped article is substantially entirely formed of a foamed polymer material having a glass transition temperature greater than 160° C. and being halogen-free is provided. A data communications cable comprising a plurality of conductors and the cable separator of the present invention, wherein said cable separator separates the plurality of conductors is provided. A method of manufacturing a cable comprising the separator of the invention is also provided.
Abstract:
Cables including a heat-reflective layer are disclosed. The heat-reflective layer includes a polymeric layer and metal particles. The metal particles are on or near the exposed surface of the heat-reflective layer. Methods of making a heat-reflective layer and cables including a heat-reflective layer rare 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 C119.4-2004 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 C119.4-2004 with the same amount of imparted current. Methods are also provided.
Abstract:
A cable includes a jacket, a shielding tape, a pair of wires, an inner and outer jacket layer, and a separator. The shielding tape includes a substrate and a plurality of conductive shield segments disposed on the substrate. The pair of wires form a twisted pair. The inner and outer jacket layers are extruded onto inner and outer surfaces, respectively, of the substrate. The substrate, the inner jacket layer and the outer jacket layer are bonded together into a single layer that defines a circumference. Each of the conductive shield segments: extends only partially around the circumference of the single layer; is longitudinally spaced from each longitudinally adjacent one of the conductive shield segments; is radially spaced from, and overlaps a portion of, each immediately circumferentially adjacent one of the conductive shield segments; and is embedded in at least one of the inner jacket layer and the outer jacket layer.
Abstract:
A fire retardant composition is disclosed. The composition includes polyvinyl chloride, a plasticizer, a brominated fire retardant additive, a fire retardant synergist, and a metal stabilizer. Cable separators formed of the fire retardant composition are also disclosed.
Abstract:
A heat shield for use with cables in a nuclear environment can include a thermal insulator. The thermal insulator can have a low thermal conductivity and can be formed of a silica glass fiber material, an aerogel, or an aerogel-derived material. The heat shield can mitigate a 650° C. temperature spike caused by a severe accident condition. Cables including such heat shields can operate through a nuclear accident that causes an initial 650° C. temperature spike.
Abstract:
A cable including a conductive composite core formed from braided carbonized fibers and fiberglass fibers. At least a portion of the fiberglass fibers are coated with magnetic material to suppress electromagnetic interference noise. Methods of forming such cables is also provided herein.
