PPC Insulators is a technology leader and manufacturer of state-of-the-art electrical porcelain insulators for overhead transmission lines, substations and electrostatic precipitator applications.
Traditional porcelain insulators originated in the late 19th century. These were further developed in-house by PPC via its isostatic production technology, allowing the production of high-quality products with efficient designs, tightest tolerances and shorter lead times for applications up to 1200kV AC and 1100kV DC.
Our production capacity presents 6500t of porcelain per year.
