Surge Protection Device

Surge protection device (SPD), also known as lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instrumentation, and communication lines. When a peak current or voltage is suddenly generated in an electrical circuit or communication line due to external interference (such as lightning), the surge protector can conduct and shun the current in a very short period of time, thereby avoiding the damage of the surge to other equipment in the circuit.

The basic components used in surge protectors are: discharge gap, gas-filled discharge tube, varistor, suppression diode and choke coil. The surge protector is suitable for protecting the safety of equipment and ensuring the normal operation of the system in the family residence, the tertiary industry and the industrial field.
