PFISTERER 33KV Inner Cone Plugs

PFISTERER’s 33KV inner cone plugs are designed to connect polymeric insulated cables into gas insulated switchgear, ring main units, circuit breakers, high voltage motors, transformers, transducers and sealing boxes.

Inner cone plugs are extensively used to terminate high voltage 33kV cables into GIS (gas insulated switchgear) and include a screened separable plug-in connector and inner cone suitable for terminating graphite coated, fully bonded or “easy-strip” semi-conducting screened high voltage cables. 33kV inner cone plugs are suitable for all kinds of insulated plastic cables but customer specific versions can be produced to be suitable for any cable type.

The PFISTERER 33kV inner cone plugs exclude steel wire armour (SWA) earthing and heat-shrink cable breakouts for sealing 3 core cable crotches and are designed to meet the following regulations:

  • EN 50180 – Bushing for liquid filled transformers up to 52kV
  • EN50181 – Plug-in type bushing up to 33/36kV for equipment other than filled transformers
  • DIN 47637 – Separable accessories for power cable for bushing with inside cone

PFISTERER’s 33kV inner cone plugs have a number of key benefits:

  • No liquid insulating medium
  • No need to open the cable termination at the installation site
  • Deckwater-proof
  • Suitable for outdoor use
  • Thorough transformer and GIS testing by manufacturer possible
  • Metal enclosed
  • Fully insulated
  • Touch proof
  • Free from arcing
  • High short-circuit protection
  • Maintenance free
  • Soil- and offshore-proof (optional)
