Cable connection

Possible combinations of cable connection types (T-plugs, coupling inserts) and
surge arresters in NXPLUS C Wind up to 36 kV
For gas-insulated switchgear NXPLUS C Wind, basically only cable plugs shielded by means of
an external semi-conductive layer (also called screened cable T-plugs) can be used. This
external semi-conductive layer must be earthed. Earthing is normally done through a cable
connection.
Insulated cable T-plugs (without external semi-conductive layer) are not permissible, as this
plug type often produces partial discharges due to the proximity to earthed parts of the
switchgear. Partial discharges destroy the cable T-plug, causing an arc between phase and
earth.
The connection of conventional cable sealing ends via elbow adapters, e.g. type AKE, is not
permissible either, as this connection system is also insulated and not screened (no external
semi-conductive layer).
