Title (EN) FIRE-RESISTANT CABLE
(FR) CÂBLE RÉSISTANT AU FEU

Abstract: front page image
(EN)The present invention relates to a fire-resistant cable. The fire-resistant cable comprises a heat-expandable polyolefin resin layer and a ceramic mica tape layer. The heat-expandable polyolefin resin layer is formed on an outer surface of an insulated conductor, and self-expands as the temperature rises, to form a charring layer having an air gap. The ceramic mica tape layer is formed on the outer surface of the heat-expandable polyolefin resin layer, and is made of a ceramic mica tape, wherein ceramic fibers are attached to an inner surface of the mica tape. The fire-resistant cable comprises said heat-expandable polyolefin resin layer and said ceramic mica tape layer, such that the ceramic mica tape layer prevents heat from quickly penetrating into the fire-resistant cable and minimizes the deformation of the cable, and the heat-expandable polyolefin resin layer prevents the transfer of heat and thus effectively prevents the temperature of the interior of the cable from rising excessively when the cable is exposed to a high temperature upon the outbreak of a fire or the like.
(FR)La présente invention a pour objet un câble résistant au feu. Le câble résistant au feu comprend une couche de résine polyoléfinique thermo-expansible et une couche de bande de mica céramique. La couche de résine polyoléfinique thermo-expansible est formée sur une surface externe d'un conducteur isolé, et s'auto-dilate lorsque la température s'élève, pour former une couche de carbonisation ayant un entrefer. La couche de bande de mica céramique est formée sur la surface externe de la couche de résine polyoléfinique thermo-expansible, et est constituée d'une bande de mica céramique, des fibres céramiques étant fixées sur une surface interne de la bande de mica. Le câble résistant au feu comprend ladite couche de résine polyoléfinique thermo-expansible et ladite couche de bande de mica céramique, de telle sorte que la couche de bande de mica céramique empêche la chaleur de pénétrer rapidement dans le câble résistant au feu et minimise la déformation du câble, et que la couche de résine polyoléfinique thermo-expansible empêche le transfert de chaleur et empêche ainsi efficacement la température de l'intérieur du câble de s'élever excessivement lorsque le câble est exposé à une température élevée lors du déclenchement d'un incendie ou analogue.
(KO)본 발명은 내화 케이블에 관한 것이다. 내화 케이블은 열팽창성 폴리올레핀 수지 층과 세라믹 운모 테이프 층을 포함한다. 내화 케이블은 열팽창성 폴리올레핀 수지 충과 세라믹 운모 테이프 층을 포함한다. 열팽창성 폴리올레핀 수지 층은 절연된 도체의 외측에 형성되며 온도가 상승함에 따라 스스로 팽창하여 공극을 갖는 차 층(charring layer)을 형성한다. 세라믹 운모 테이프 층은 상기 열팽창성 폴리올레핀 수지 층의 외측에 형성되며 세라믹 섬유가 운모 테이프의 내측에 접착되어 형성되는 세라믹 운모 테이프로 형성된다. 내화 케이블이 열팽창성 폴리올레핀 수지 층과 세라믹 운모 테이프를 구비함으로써, 화재 등에 의해 고온에 노출된 경우에 세라믹 운모 테이프의 작용에 의해 열이 급격히 침투하는 것을 방지하고 케이블의 변형을 최소화함과 동시에 열팽창성 폴리올레핀 수지 층의 열 전달 차단 작용에 의해 케이블 내측의 온도가 지나치게 상승하는 것을 효과적으로 방지할 수 있다.
