Wall Bushings

Up to 245kV fully insulated resin impregnated molded and silicone rubber insulator Outdoor-Indoor bushings for applications for transformers, generation facilities, station mounted.

The DURESCA© wall bushings have a dry insulation of RIP (Resin Impregnaterd Paper).  The insulation lays directly on the conductor or tube and consists of wrapped paper direct under vacuum impregnated with epoxy resin.  Conductive grading layers are emebedded during the wrapping in the insulation for the best field control.  This guarantees the highest operational and human safety.

The DURESCA© wall bushings are available in two designs:

Type DEM - available with a diameter of Dfl of the flange up to 170 mm.  The insulated body is covered with a high quality corrugated protection tube in polyamide.

Type DM -  used with a diameter Dfl with more than 170 mm.  The insulation body is covered with a high quality varnish.

  • Highest operational safety and lifetime guarantee through high grade condensor RIP insulation
  • Partial discharges free operation
  • Compact, lightweight design through use of silicone rubber insulator
  • Earthquake and explosion resistant
  • Pollution resistant
