Abstract

Patente de Invenção: <B> "CABO DE COMUNICAçõES PARA INSTALAçãO AéREA"<D>. Um cabo de comunicações é apresentado tendo um cabo de sustentação e pelo menos um cabo coaxial helicoidalmente enrolado em torno do cabo de sustentação. O cabo coaxial inclui um condutor interno, um dielétrico circundando o condutor interno, um envoltório metálico tubular externo circundando o dielétrico, e opcionalmente uma camisa protetora circundando o envoltório metálico. O cabo de comunicações é de tal maneira fabricado que a relação do comprimento do cabo coaxial para o comprimento do cabo de sustentação está entre cerca de 1,005 e 1,015. O cabo de comunicações é também de preferência enrolado em torno do cabo de sustentação utilizando um segmento de cochar variável desa maneira minimizando a perda de sinais devido a dano ao cabo. O cabo de comunicações da invenção é especialmente apropriado para instalação aérea e pode ser instalado em uma só passagem, sem a necessidade da formação de alças de expansão no cabo coaxial.Invention Patent: <B> "COMMUNICATION CABLE FOR AERIAL INSTALLATION" <D>. A communications cable is shown having a support cable and at least one coaxial cable helically wound around the support cable. The coaxial cable includes an inner conductor, a dielectric surrounding the inner conductor, an external tubular metallic wrap surrounding the dielectric, and optionally a protective jacket surrounding the metallic wrap. The communications cable is so manufactured that the ratio of the length of the coaxial cable to the length of the support cable is between about 1.005 and 1.015. The communications cable is also preferably wrapped around the support cable using a variable coach segment in such a way as to minimize signal loss due to cable damage. The communication cable of the invention is especially suitable for aerial installation and can be installed in one pass, without the need for the formation of expansion loops in the coaxial cable.
