Abstract

"CABO COM PROTEçãO DE CORROSãO EM FRESTAS". A invenção refere-se a um cabo que compreende pelo menos dois elementos alongados escolhidos de um grupo que consiste em tubos de aço (1, 2), cabos de fibra óptica (3), cabos elétricos (4) e suas combinações, dispostos lado a lado dentro de uma cobertura externa comum (5) ao longo do comprimento da linha e onde pelo menos um dos elementos alongados (1, 2) tem uma superfície externa de metal passivo, a dita cobertura externa (5) permitindo a entrada do agente corrosivo para os interstícios entre os elementos, caracterizado pelo fato de que pelo menos um dos elementos (1, 2) com uma superfície externa de metal passivo é provido com uma camada externa (1A, 2A) formada de um material com estrutura aberta para a passagem da água e que tem uma espessura controlada.
