Advantage of Composite Station Post Insulator:
Composite insulators are suitable for substations, because it is difficult to detect zero-value insulators in stations due to power failure, and it is inconvenient to clean, and it is difficult to carry out post-maintenance with porcelain and glass insulators. For the existing substation, the composite insulator may also be replaced according to the site pollution degree and the actual situation.
