El DALIAN LB7-220(GY)<\/strong> es un transformador de corriente tipo horquilla (Hair-pin<\/em>) sumergido en aceite, desarrollado para sistemas el\u00e9ctricos con tensi\u00f3n nominal de 220 kV<\/strong> y tensi\u00f3n m\u00e1xima del equipo de 252 kV<\/strong>.\u00a0Su funci\u00f3n es transformar las corrientes elevadas del sistema en valores secundarios normalizados para su utilizaci\u00f3n por equipos de medici\u00f3n, protecci\u00f3n, supervisi\u00f3n y control<\/strong> en subestaciones y sistemas de alta tensi\u00f3n.<\/p>\n

El modelo admite diferentes relaciones de corriente primaria, desde 2 \u00d7 100 A hasta 2 \u00d7 1250 A<\/strong>, dependiendo de la configuraci\u00f3n requerida. La corriente secundaria nominal puede ser de 1 A o 5 A<\/strong>, con distintas clases de precisi\u00f3n para medici\u00f3n y protecci\u00f3n.<\/p>\n
