Insulators are widely used in overhead transmission lines to provide mechanical support and electrical protection, as well as in distribution lines and substations.
The butterfly insulators and pin insulators in ceramic insulator products are mainly used for high and low voltage transmission lines, and suspension insulators are used for high voltage transmission lines.
A surge arrester is a device to protect electrical equipment from over-voltage transients caused by external (lightning) or internal (switching) events.
Haivo polymer housed zinc oxide surge arrester has passed the short- circuit test successfully in XIHARI again in 20th of April 2021 (National quality supervision & inspection center for insulator & surge arrester).
Application of silicone composite insulators has increased significantly over the past 30 years. One of the key factors behind continued growth will be the confidence shown in them by power utilities.
