Product Description

Solid Insulated Switchgear (SIS) replaces traditional gas insulation with epoxy-resin-encapsulated components, eliminating greenhouse gases while delivering superior performance in 12-40kV networks. By embedding live parts in maintenance-free solid dielectric, SIS achieves ultra-compact dimensions, immunity to environmental contaminants, and >30-year lifecycle reliability. Compliant with IEC 62271 standards, it's the go-to solution for decarbonizing power infrastructure without compromising safety or space efficiency.
