Abstract:
A cable including a conductor surrounded by a covering layer, the covering layer formed from a thermoplastic vulcanizate composition which includes a continuous phase and a dispersed phase. The continuous phase is formed of a thermoplastic polyolefin. The dispersed phase is formed of a cross-linked elastomeric polyolefin. The thermoplastic vulcanizate composition passes the Hot Creep Test at 150° C. in accordance with UL 2556 (2013) and has a dielectric loss of 3 or less. Methods of forming cables with coverings are also disclosed.
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:
An electrical cable includes a plurality of conductors forming a conductor core, one or more insulation layers at least partially surrounding at least one of the plurality of conductors, an outer jacket surrounding the conductor core and a film applied to the exterior surface of the outer jacket. The film includes high visibility particles. Methods of forming electrical cables are also described herein.
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:
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:
Systems and methods to apply an on-demand color scheme to a cable are described. The systems and methods include the application of a plurality of colored coating fluids to an outer cable layer.
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:
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.
Abstract:
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.
