Why Is The Investment Cost Of Insulator Lightning Protection So High?

The investment cost of high voltage transmission line insulators lightning protection is relatively large, mainly because overhead power line insulators has high requirements for lightning protection performance and relatively complex materials and manufacturing processes. In order to improve the lightning protection capability of the power system, tension insulator needs to use high-strength, high-temperature resistant and corrosion-resistant materials. These special materials are expensive. In order to achieve better lightning protection effect for dead end insulators, dead end suspension insulators needs to be tested and verified multiple times to ensure its reliability under various harsh environmental conditions.
