Abstract

DISPOSITIVO ISOLANTE DE SUSTENTAçãO E DE PROTEçãO DE LINHAS. A presente invenção refere-se a um dispositivo isolante de sustentação e de proteção de linhas, em peça única, que reúne as funcionalidades de sustentar mecanicamente os condutores, mantendo-os eletricamente isolados da estrutura aterrada bem como protegendo a linha de transmissão e as partes do sistema contra sobretensões, o dispositivo compreendendo um núcleo isolante (10) e pelo menos um anel (20) de resistor não linear, com composição a base de óxido de zinco, estando eletricamente conectado entre os terminais metálicos (30) externos, o primeiro terminal (30) sendo conectado a pelo menos um condutor e o outro terminal (30) conectado à estrutura aterrada, o referido núcleo (10) e o pelo menos um anel (20) de resistor não linear sendo ainda revestidos com material polimérico (15)INSULATING SUPPORT AND LINE PROTECTION DEVICE. The present invention relates to a one-piece insulating support and line protection device which combines the functionality of mechanically supporting the conductors, keeping them electrically isolated from the grounded structure as well as protecting the transmission line and parts. of the overvoltage system, the device comprising an insulating core (10) and at least one non-linear resistor ring (20) of zinc oxide composition, being electrically connected between the external metal terminals (30), the first terminal (30) being connected to at least one conductor and the other terminal (30) connected to the grounded structure, said core (10) and at least one nonlinear resistor ring (20) being further coated with polymeric material (15). )
