Spool insulators are used with spool bolts (upset bolts) clevises, secondary racks and various brackets for deadending or supporting secondary voltage conductors.
We have experience with the manufacture of post insulators since 1986.
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.
The spool insulator is equipped with more than two umbrella buildings. The conductor is bound in the middle of the upper and lower umbrella buildings, and the center is perforated. It is fixedly connected to the cross arm or splint with threading nails
