Pfisterer CONNEX Separable Connectors Size 0 24kV 250A 25-70sqmm Cables
MV-HV Switchgear & Transformer Cable Terminations – 11kV 12kV 24kV
Pfisterer CONNEX size 0 inner cone cable plugs terminate MV-HV power cables into GIS (gas insulated switchgear) with inner cone bushings size 0 (250A amps) – size 0 CONNEX connectors are specified for cable terminations at 11kV-12kV up to 24kV operating voltages.
Pfisterer size 0 inner cone plug separable connectors are suitable for terminating and connecting high voltage single core cables (XLPE EPR) with copper wire screens up to 24kV – CONNEX plugs suitable for indoor and outdoor cable terminations with or without voltage taps.
The following Video provides an overview of the Installation Procedure for CONNEX Connectors for the termination of Medium/High Voltage (MV-HV) Cables manufactured by Pfisterer and stocked by Thorne & Derrick – should you require specification support, technical guidance or Jointer training services please call us to discuss.
