PPC Insulators is a world leader and innovator for electrostatic precipitation technology and applications. Products have been designed, engineered and manufactured in PPC manufacturing plants since the 1970’s.

E-Filter insulators are made up of a high resistivity LD Ceramic body containing approx. 50% Alumina. It’s a high-grade ceramic material with very good mechanical and electrical properties.

 

E-Filter insulators have a number of outstanding technical features including:

  • High DC resistivity at high temperatures
  • Excellent mechanical strength and impact resistance
  • Very low thermal expansion
  • Glazed surface enables easy visual inspection and easy cleaning

The benefits of E-Filter products are the density degree of 95% and no open porosity to prevent water absorption. The glazing of our E-Filters insulators serves the dual purpose of providing the products with a combined dirt and dust-repelling surface to facilitate inspection, cleaning and to avoid tracking and discharges along the insulator surface.
