El fusible de corte de polímero de 15kV 100A reemplaza el aislador de porcelana tradicional con material aislante compuesto de goma de silicona, que tiene las características del peso liviano (reducción del peso en un 50%), resistencia al impacto, destello de anti-contaminación y vida larga (≥ 30 años), adecuada para:
Ambientes duros: alta humedad, fuertes rayos ultravioleta, áreas de rociado de sal costero
Escenarios de operación frecuentes: líneas de colección fotovoltaica/de energía eólica, unidad principal del anillo urbano
Altos requisitos de confiabilidad: no hay necesidad de limpieza regular, diseño sin mantenimiento
