20110308836 | INSULATION CONTAINING STYRENE COPOLYMERS - The invention relates to cover compositions for electric power cables having a polyolefin and a styrene copolymer. The styrene copolymer 1) has a styrene content of 55 percent (by weight base on the total styrene copolymer) or greater; 2) contains a random arrangement of styrene and at least one other block polymer; and/or 3) contains a triblock having the formula S-AS-S, wherein S is styrene and A is alkylene or a mixture of different alkylenes. The cover can be an insulation or a jacket. | 12-22-2011 |
20120273250 | INSULATION COMPOSITIONS - The present invention relates to insulation compositions. In an object of the present invention, the compositions contain a fluoropolymer, a poly(arylene ether) and a styrene block copolymer. The compositions maintain substantially similar electrical properties and flame retardancy, and have reducing cost and density when compared to fluoropolymers alone. | 11-01-2012 |
20140329088 | EASY CLEAN CABLE - Cables having a conductor with a polymeric covering layer and a non-extruded coating layer made of a material based on a liquid composition including a polymer resin and a fatty acid amide. Methods of making cables are also provided. | 11-06-2014 |
20150179307 | HIGH VISIBILITY CABLE - 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. | 06-25-2015 |
20150194237 | SELF-CLEANING CABLE ASSEMBLIES - The present disclosure relates to a self-cleaning cable assembly useful for overhead high voltage electricity transmission. The self-cleaning 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. The present disclosure also relates to methods of reducing surface buildup on cable assemblies for overhead high voltage electricity transmission. | 07-09-2015 |
20150194240 | COATED OVERHEAD CONDUCTOR - 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. | 07-09-2015 |
20150228376 | CABLES WITH IMPROVED COVERINGS AND METHODS OF FORMING THEREOF - 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. | 08-13-2015 |
20150376369 | THERMALLY CONDUCTIVE COMPOSITIONS AND CABLES THEREOF - 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. | 12-31-2015 |
