Surge arresters are the foundation of the insulation coordination of various electrical equipment in power systems (transformers, reactors, capacitors, generators, motors, PTs, CTs, circuit breakers, contactors, and all other medium- and high-voltage electrical equipment). The protection performance of surge arresters determines the internal and external insulation indicators (short-time power frequency withstand voltage, lightning impulse withstand voltage, and operating impulse withstand voltage, etc.) of all electrical equipment in the power system. Metal Oxide surge Arresters (MOAs) are advanced products among conventional surge arresters. The core working element uses a multi-metal oxide powder mainly composed of zinc oxide, which has excellent non-linear voltage-current characteristics, fast steep wave response, and large current carrying capacity.

Metal Oxide surge Arresters (MOAs) are advanced products among conventional surge arresters. Their core working components are made by sintering a multi-metal oxide powder with zinc oxide as the main component. They possess excellent non-linear volt-ampere characteristics, fast steep wave response, and large discharge current.

The grading ring is primarily used for voltage equalization and is suitable for AC voltages. It evenly distributes the high voltage around an object, ensuring that there is no potential difference between any points within the ring, thereby achieving voltage equalization.
