HJ-SIS Series (Solid Insulated Switchgear)

Name: HJ-SIS Series (Solid Insulated Switchgear)
Brand: HJATIS

The HJ-SIS Series is solid-insulated ring main switchgear for distribution systems up to 24 kV. Epoxy-resin insulation avoids the use of SF6 in the primary insulation system, and live parts are sealed and screened. Catalogue configurations start at 400 mm cabinet width; confirm access, maintenance, ratings and IEC 62271-200 test evidence for the offered assembly.
