Introdu\u00e7\u00e3o geral<\/strong><\/h2>\n

O disjuntor Sf6 externo tipo LW8A-40.5 de 12kv 24kv 33kv \u00e9 um dispositivo externo usado no sistema de energia trif\u00e1sico de 40,5KV de CA 50HZ. \u00c9 aplic\u00e1vel a locais que precisam operar com frequ\u00eancia na corrente nominal ou sob corrente de curto-circuito repetidamente ligada\/desligada. Contendo o transformador de corrente para medi\u00e7\u00e3o e prote\u00e7\u00e3o, ele pode substituir diretamente o disjuntor a \u00f3leo SW2-35 e v\u00e1rios tipos de disjuntores a \u00f3leo com suporte de transi\u00e7\u00e3o. Ele tamb\u00e9m pode ser usado como um disjuntor de liga\u00e7\u00e3o e em situa\u00e7\u00f5es de grupo de capacitores de comuta\u00e7\u00e3o com mecanismo de mola do tipo CT14.<\/p>\n
