Hollow insulators

Hollow insulators are main products used for substations, so they also called hollow station post insulators. Innovative insulator design and high voltage hollow insulators need advanced technology.

Innovative insulator design of Hollow insulators:
The traditional high voltage insulators are subject to new developments focusing on improved performance with reduced dimensions. The design of hollow insulators has long been restricted by limitations in material and production processes, complicating the introduction of new insulator designs. Long lead times required for engineering, preparation and tooling has mandated product uniformity and strict recommendations at the cost of function-specific design.
