Abstract

"DISPOSITIVO DE CABO ELéTRICO COM ATENUAçãOREDUZIDA E MéTODO PARA FABRICAçãO". Modalidades dainvenção incluem um dispositivo de cabo elétrico decomunicações e método para fabricação. O cabo elétrico decomunicações compreende um meio de transmissão deinformações tal como um condutor elétrico isolado ou um par decondutores elétricos, uma camada separadora formada em tornodo meio de transmissão e um invólucro protetor de cloreto depolivinila de pouca fumaça (LSPVC) formado em torno da camadaseparadora. A camada separadora é feita de, por exemplo,politetrafluoroetileno (PTFE) ou outro material dielétrico adequado.Alternativamente, o dispositivo de cabo de comunicações incluiuma canelura para separar condutores elétricos isolados naquele.Um método para fabricar cabo de comunicações compreendepropiciar um meio de transmissão tal como um condutor elétricoisolado, um par de condutores elétricos ou uma pluralidade depares de condutores elétricos, formar uma camada separadora emtorno do meio de transmissão e formar um invólucro protetor deLSPVC em torno da camada separadora. A camada separadora éfeita de um material dielétrico adequado tal como PTFE ou fita dePTFE. A camada separadora melhora as propriedades dielétricasdo cabo de tal modo que a atenuação de sinais que se propagamao longo de condutores dentro do cabo é reduzida. Também, acamada separadora reduz a tensão entre o invólucro protetor e omeio de transmissão, melhorando deste modo as características deatenuação do cabo e permitindo que porções do invólucro protetorsejam retiradas mais facilmente do que em configuraçõesconvencionais de cabos de comunicações."ELECTRICAL CABLE DEVICE WITH REDUCED ATTENUATION AND METHOD FOR MANUFACTURING". Invention modalities include an electrical communications cable device and manufacturing method. The electrical communications cable comprises an information transmission medium such as an isolated electrical conductor or a pair of electrical conductors, a separating layer formed around the transmission medium and a low smoke depolyvinyl chloride (LSPVC) protective casing formed around the separating layer. The separating layer is made of, for example, polytetrafluoroethylene (PTFE) or other suitable dielectric material. Alternatively, the communications cable device included a flute to separate insulated electrical conductors therein. A method for making communications cable comprises providing such a transmission medium as an isolated electrical conductor, a pair of electrical conductors or a plurality of pairs of electrical conductors, form a separating layer around the transmission medium and form a protective LSPVC wrapper around the separating layer. The separating layer is made of a suitable dielectric material such as PTFE or PTFE tape. The separating layer improves the dielectric properties of the cable in such a way that the attenuation of signals that propagate along conductors within the cable is reduced. Also, the layer separator reduces the tension between the protective housing and the transmission medium, thereby improving the cable's attenuation characteristics and allowing portions of the protective housing to be removed more easily than in conventional communications cable configurations.
