O fusível de corte de polímero de 15kV 100A substitui o isolador tradicional de porcelana por material isolante composto de borracha de silicone, que tem as características de peso leve (redução de peso em 50%), resistência ao impacto, flashver anti-poluição e vida longa (≥ 30 anos), adequada para:
Ambientes severos: alta umidade, fortes raios ultravioleta, áreas de spray de sal costeiro
Cenários de operação frequentes: linhas de coletor de energia fotovoltaica/eólica, unidade principal do anel urbano
Requisitos de alta confiabilidade: não há necessidade de limpeza regular, design sem manutenção
