The INEXT are very reliable high quality SF6 insulated pole mounted on-load disconnectors for outdoor installations in distribution networks available with rated voltages from 24 to 36kV and rated currents 400 or 630A. They are installed in horizontal position.

The SF6 enclosure is made out of stainless steel and is fully welded. Their operation can be done manually or motorized. A clear signal indicates the open and closed positions.

The INEXT are available in following versions:

"AA" - aerial line conductor for incoming and outgoing cable
"AS" - aerial line conductor for incoming cable and isolated cable outgoing
"SS" - incoming and outgoing with isolated cable

The disconnectors are type tested according to IEC 62271-100 and designed for use under normal operating conditions.
