Arresters, including metal oxide, line-type metal oxide, gapless line-type metal oxide, fully insulated composite jacket metal oxide, and detachable arresters, are used to protect communication cables and equipment. They are connected in parallel between the cable and the ground. When abnormal voltage occurs, the arrester activates to divert the surge current to the ground, safeguarding the insulation of the protected equipment. The arrester remains inactive under normal working voltage, acting as an open circuit to the ground. Its main function is to reduce overvoltage and protect communication lines and equipment. National standards classify different pollution levels based on creepage ratio grades.
