Porcelain Post Insulator

Reliable use in plant construction

insulator_01_02_post

The post insulators from the latest high performance ceramics have been in use for many decades in switchgear and capacitor bank platforms. We have experience with the manufacture of post insulators since 1930. Research and further development resulted in the optimization of our post insulators for distribution plants and switchgear systems.

In accordance with the standards IEC, ANSI, CSA and other certifications we manufacture single-component series up to a length of 90 inches and voltage levels up to 1100 kV. Our post insulators are mainly exposed to pressure, bending and torsional forces during operation and have been specifically designed for this purpose. We are also happy to offer our customers a customized full-service solution tailored ideally to their requirements.
