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

The main types of surge protectors include tube-type, valve-type, and zinc oxide surge protectors, among others. Each type of surge protector operates on a different principal, but their fundamental function is the same; they are all designed to protect communication cables and equipment from damage.
