Abstract

Cette invention concerne un câble plat à l'épreuve des flammes, lequel possède une structure obtenue en laminant autant de conducteurs que nécessaire avec deux films, à savoir un film inférieur et un film supérieur, qui se composent de PTFE ou de PTFP. Ces conducteurs peuvent également être enrobés d'un matériau à base de résine de PTFE ou de PTFP. Les surfaces de laminage des films inférieur et supérieur sont laminées avec un film d'éthylène propylène fluoré (FEP), lequel leur confère une bonne aptitude au contact lorsque lesdits films inférieur et supérieur sont soumis au laminage. Cette invention concerne également un procédé de fabrication d'un câble plat à l'épreuve des flammes, lequel procédé consiste à envoyer vers un laminoir plusieurs conducteurs provenant d'un bâti, puis à les préchauffer à une température allant de 260 à 659° C (500 à 1200° F) à l'aide de deux unités de chauffage du noyau. Un film inférieur est ensuite introduit sous les conducteurs tandis qu'un film supérieur est amené au-dessus desdits conducteurs, ceci entre des unités de chauffage à infrarouges supérieure et inférieure, et entre des patins de chauffage inférieur et supérieur. Les conducteurs sont laminés avec les films inférieur et supérieur à l'aide d'un cylindre de chauffage inférieur et d'un cylindre de chauffage et de presse supérieur, ceci de manière à former un câble plat laminé. Le câble plat laminé ainsi obtenu est enfin refroidi à l'aide d'un système de refroidissement comportant deux cylindres de refroidissement.
