Abstract
"MéTODOS PARA PRé-AQUECER ELEMENTOS CONDUTORES DE CABOS E PARA FABRICAR UM CABO, APARELHO PARA PRé-AQUECER OS ELEMENTOS CONDUTORES DE CABOS, E, INSTALAçãO PARA FABRICAR UM CABO". O método e aparelho da invenção usam pré-aquecimento essencialmente por convecção térmica forçada. Particularmente, para condutores com reforço de fita metálica, tais como, por exemplo, os condutores Milliken, onde se observou que o aquecimento por indução ética tradicional não é satisfatório, uma vez que o reforço de fita isola os elementos condutores.
