    Production and testing of our ESP insulators

    We are ceramic specialists dedicated to the development, manufacturing, and supply of insulators for electrostatic precipitators (ESP), MV substations and industrial applications. Our insulators are manufactured using a modern and fully automated process. Each manufactured insulator undergoes rigorous quality  output inspection. Every production batch is subjected to both routine and sample testing according European standards, ensuring safe and reliable use for our customers. 

    As one of the few manufacturers globally, we have the capability to produce insulators for electrostatic precipitators that withstand high operational temperatures of 500°C and are less susceptible to thermal shocks. These insulators are crafted from high-alumina porcelain with a composition of 95% Al3O3.
