YH5WZ lightning arrester is a kind of lightning protection equipment specially designed for power system, mainly used to protect power equipment from lightning overvoltage, to ensure the stable operation of power system. YH5WZ arrester is made of advanced technology and materials, with excellent performance and reliability, widely used in various power system scenarios ; The working principle of the YH5WZ arrester is based on the characteristics of the metal oxide nonlinear resistance. During normal operation, the arrester presents a high resistance state, which does not affect the normal operation of the power system. When the power system is subjected to lightning shock and overvoltage is generated, the metal oxide resistor in the arrester will act quickly, showing a low resistance state, and introduce the lightning current to the ground, thereby limiting the amplitude of the overvoltage and protecting the power equipment from damage
