Connecting cable T-plugs

For NXPLUS C switchgear, only cable T-plugs shielded by means of an external semi-
conductive layer may be used as a rule. The suitable cable plugs for outside-cone bushings of
interface type C according to EN 50181 are listed in the section "Description" (see page 34,
"Cable connection"NXPLUS C).
Please select the tightening torque of the bolted joint "cable T-plug - bushing" according to the
specifications of the respective cable T-plug manufacturer.
If there are no specifications from the cable T-plug manufacturer's side, please tighten the
bolted joint with 50 Nm.
