Post Insulator Lightning Arrester

Surge protectors come in various types, including metal oxide surge protectors, line-type metal oxide surge protectors, gapless line-type metal oxide surge protectors, full-insulated composite sheath metal oxide surge protectors, and removable surge protectors.

The main types of surge protectors include tube-type surge protectors, valve-type surge protectors, and zinc oxide surge protectors, etc. Each type of surge protector operates on a different principle, but their fundamental function is the same – to protect communication cables and equipment from damage.
