The lightning arrester is connected in series on the equipment to prevent the equipment from being damaged by lightning by transmitting excessive voltage and current to the equipment when lightning strikes the equipment. Through series lightning arrester, excessive voltage and current can be introduced into the lightning arrester when lightning strikes, and the lightning arrester can disperse and consume the energy of voltage and current to protect the equipment. Therefore, in order to ensure the safety and reliability of the equipment, it is very important to use the signal lightning arrester and connect it in series on the equipment.
