A metal oxide arrestor (MOA) is an electrical device that is designed to protect electrical systems and equipment from surges caused by lightning, switching operations, and other sources of overvoltage. The MOA technology utilizes a mov arrester element that provides low impedance paths for high voltage surges, thereby diverting the excess energy to the ground.

Medium voltage surge arresters are electrical devices designed to protect electrical equipment from surges or transients that occur on medium-voltage power systems. These systems typically operate at voltages between 1kV and 36kV, and they are commonly found in various industries, such as manufacturing, oil and gas, and utilities.

Railroad glass insulators are a critical component in ensuring the safety and operational efficiency of railway systems. These insulators are specifically designed to provide a durable and reliable means of securing and isolating electrically charged rails from each other and the rest of the railway infrastructure. One of the leading brands of rail insulators on the market is YF POWER, which offers a range of high-quality insulators that are designed to meet the stringent requirements of modern railway systems.
