With more than 90 years of experience in designing and manufacturing railway porcelain insulators, PPC has developed a new concept to improve safety and performance while optimizing cost considerations for our customers.

Our research, in conjunction with national and transnational railway companies, yielded a high-grade design for C130 porcelain material with the optimum cement for assembly and fittings. The high-grade quality properties of this porcelain material allow a smaller core diameter, smaller sized fittings and make the insulator lighter than porcelain from other manufacturers.



Three kinds of assemblies for mating fittings to the porcelain:

  • Lead antimony alloy
  • Sulfur cement
  • Portland cement


Overhead line catenary

PPC single piece core insulators are designed to work in the horizontal position or are angle mounted on a crossarm, providing maximum safety for the electrical line connection with the train.
