| 20110198108 | COMPOSITIONS FOR RISER AND PLENUM CABLES - The present invention relates to materials for making cable jackets, particularly riser and plenum cables. The materials provide low flammability and allow the cable to meet UL 910 or NFPA 262 or UL 1666 specifications. The material contains PVC resin, a plasticizer, a metal oxide particle, and optionally a brominated phthalate. Preferably, the metal oxide particle is spherical amorphous silicon dioxide. More preferably, the spherical amorphous silicon dioxide has a mean particle size of about 100-200 nm and/or a BET surface area of about 10-30 m | 08-18-2011 |
| 20110290527 | HALOGEN-FREE FLAME RETARDANT POLYOLEFIN - The present invention relates to halogen-free compositions containing an additive of bohmite, nanoclay, microcrystalline talc, zinc hydroxystannate, and a polyolefin oil. The composition is useful as a covering material (e.g. insulation or jacket) for electrical cables with excellent flame resistance and mechanical properties, such as cold bend and thermomechanical properties. | 12-01-2011 |
| 20120012362 | DC POWER CABLE WITH SPACE CHARGE REDUCING EFFECT - Provided is a DC power cable including a conductor, an inner semiconductive layer, an insulation and an outer semiconductive layer. In particular, the inner semiconductive layer or the outer semiconductive layer may be formed from a semiconductive composition containing a polypropylene base resin or a low-density polyethylene base resin and carbon nano tubes; and the insulation may be formed from an insulation composition containing a polypropylene base resin or a low-density polyethylene base resin and inorganic nano particles. The resulting power cable may have improved properties such as volume resistivity, hot set, and so on, and excellent space charge reducing effect. | 01-19-2012 |
| 20120152590 | High Temperature High Frequency Magnet Wire and Method of Making - A composite magnet wire includes, in an exemplary embodiment, a metal wire and a coating applied to an outer surface of the wire. The coating includes a polyimide polymer and a plurality of alumina nano particles dispersed in the polyimide polymer. The alumina nano particles have a surface treatment applied to outer surfaces of the alumina nano particles, where the surface treatment includes a phenyl-silane. The composite magnet wire has a thermal degradation temperature index of at least 300° C. as calculated in accordance with ASTM E1641 or D2307. | 06-21-2012 |
| 20130126210 | COVER ASSEMBLIES FOR ELECTRICAL CABLES AND METHODS AND KITS INCLUDING SAME - A method for forming a cover assembly on an electrical power transmission cable includes: mounting a tubular cover member around the cable such that a portion of the cover member defines a cavity surrounding the cable; providing a flowable electrical stress grading material in the cavity; and applying a vacuum to the cavity to evacuate air from the cavity and compact the electrical stress grading material in the cavity. | 05-23-2013 |
| 20150075841 | Article And Method For Producing An Article With A Silicone-Type Base Material And Solid Material Particles Introduced Into A Surface Of The Article - A silicone article, such as a cable with a silicone outer jacket, is improved with respect to its feel and particularly its coefficient of friction is reduced. Solid mica particles are introduced into the surface of the cable or other article. An intermediate product which has a silicone-type base material on the exterior is initially provided in a state that is not, or no more than partially, cross-linked. The solid material particles are subsequently pressed in, before the complete cross-linking takes place. The solid material particles are present only in the surface region. | 03-19-2015 |
| 20150357087 | NOISE SUPPRESSION CABLE - A noise suppression cable includes a conductor wire, and a magnetic insulation layer on a periphery of the conductor wire. The magnetic insulation layer includes an insulating material and two or more types of magnetic powders that have different frequency characteristics from each other. | 12-10-2015 |
