Substation type disconnect switches, substation type surge arresters, and post insulators that are widely used in substations with voltage levels of 33-220KV to actively ensure the stable operation of substations.
Composite suspension insulators, Composite strain insulators and lightning arresters are widely used in 110-220KV high-voltage transmission lines, which play a positive role in ensuring long-distance power transmission.
Insulators, lightning arresters, and disconnect switches are widely used in electrified railway contact networks.
