Introducci\u00f3n general<\/strong><\/h2>\n

LW8A-40.5 Tipo 12kv 24kv 33kv Interruptor de circuito Sf6 al aire libre es un dispositivo al aire libre utilizado en AC 50HZ trif\u00e1sico 40.5KV sistema de energ\u00eda. Es aplicable a lugares que necesitan un funcionamiento frecuente en corriente nominal o bajo corriente de cortocircuito repetidamente de encendido\/apagado. Contiene un transformador de corriente para medici\u00f3n y protecci\u00f3n, y puede sustituir directamente a los disyuntores de aceite SW2-35 y a varios tipos de disyuntores de aceite con soporte de transici\u00f3n. Tambi\u00e9n puede utilizarse como disyuntor de corbata y situaciones de grupo de condensadores de conmutaci\u00f3n con mecanismo de resorte tipo CT14.<\/p>\n
