Surge arresters come in many types, including metal oxide arresters, line-type metal oxide arresters, gapless line-type metal oxide arresters, full-insulated composite jacket metal oxide arresters, and removable surge arresters.

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