Insulators from PPC are synonymous with quality and reliability. Our engineers work with OEM’s in order to design tailored solutions for each and every customer.

Continuous development and investment at PPC enable us to offer insulators up to 1100kV for:


  • switchgears (DTB, LTB and GIS)
  • instrument transformers (CT and CVT)
  • power transformers
  • surge arresters
  • cable sealing ends
  • wall bushings

Insulators exceeding 2.900mm are jointed by epoxy gluing. For instance, we regularly supply 1100kV bushings with height of 10.000mm. PPC experience for this jointing technology exceed 40 years.
