Este interruptor utiliza una estructura integrada que combina un seccionador y un interruptor de vac\u00edo, lo que optimiza el dise\u00f1o general del armario al tiempo que garantiza una capacidad de corte de cortocircuito de 25 kA. Gracias al uso de una avanzada tecnolog\u00eda de extinci\u00f3n de arco al vac\u00edo, ofrece un alto nivel de seguridad y un rendimiento mec\u00e1nico estable, cumpliendo los estrictos requisitos de la norma GB\/T1984-2017 para la distribuci\u00f3n el\u00e9ctrica moderna de alta tensi\u00f3n.<\/p>\n<h3><strong><span style=\"font-size: 75%;\">Aplicaciones<\/span><\/strong><\/h3>\n<ul>\n<li>Interruptor de protecci\u00f3n primaria para instalaciones de conmutaci\u00f3n aisladas con gas (GIS) de 12 kV en redes urbanas e industriales.<\/li>\n<li>Optimizado para unidades compactas de distribuci\u00f3n de energ\u00eda que requieren aislamiento integrado e interrupci\u00f3n al vac\u00edo.<\/li>\n<li>Adecuado para subestaciones que requieran un rendimiento estable en condiciones de funcionamiento comprendidas entre -40 \u00b0C y +40 \u00b0C.<\/li>\n<\/ul>\n<h3><span style=\"font-size: 75%;\"><strong>Condiciones del entorno operativo<\/strong><\/span><\/h3>\n<ul>\n<li>Altitud no superior a 2000 m;
