Abstract:
A cable separator includes a body, and the body includes a polycarbonate-based material that is at least a partially foamed. Cables and methods of manufacturing such cables having a separator 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:
Systems and methods of coating an installed overhead conductor with an unmanned aerial vehicle are disclosed. The unmanned aerial vehicles can attach to an installed overhead conductor and can apply a coating composition from one or more canisters.
Abstract:
Thermally conductive compositions exhibiting a thermal conductivity of 0.30 W/mK or more include a base polyolefin, a halogenated flame retardant, a non-halogenated flame retardant, and a flame retardant synergist. Cables include insulation and/or jacket layers formed of such thermally conductive compositions.

Abstract:
A data cable can include a plurality of insulated conductors twisted into pairs, an intumescent tape surrounding one or more of the insulated conductors, and a jacket. Each of the plurality of insulated conductors includes a conductor and an insulation layer. Data cables being fluoropolymer-free or halogen free are also described herein.
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 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:
Thermally conductive compositions exhibiting a thermal conductivity of 0.30 W/mK or more include a base polyolefin, a halogenated flame retardant, a non-halogenated flame retardant, and a flame retardant synergist. Cables having insulation and/or jacket layers formed of such thermally conductive compositions are also described herein.
Abstract:
Coating compositions including a binder agent are disclosed. The binder agent is formed of a fluorocopolymer and a non-fluorinated film-forming polymer. Methods of coating cables with the coating compositions are also described herein.
