Surge Protector factory

Surge protective device (SPD) is also known as Duzhi lightning arrester (SPD). It is suitable for the power supply system (or communication system) with AC 50 / 60Hz and rated voltage Dao to 380V. It can protect indirect lightning and surge with direct lightning impact or other instantaneous overvoltage. It is applicable to the requirements of surge protection in home, tertiary industry and industrial field The protection modes include ground, relative middle line, middle line to ground and their combination.
Surge is also called surge, as the name implies, is the instantaneous overvoltage exceeding the normal working voltage. In essence, surge is a kind of intense pulse that occurs in only a few millionths of a second. The possible causes of surge include heavy equipment, short circuit, power switching or large engine. The products with surge blocking device can effectively absorb the huge sudden energy to protect the connected equipment from damage.
Surge protective device (SPD), also known as lightning protection device, is an electronic device that provides security protection for various electronic equipment, instruments and communication lines. When the peak current or voltage is suddenly generated in the electrical circuit or communication line due to external interference, the surge protective device (SPD) can conduct the shunt in a very short time, so as to avoid the damage of surge to other equipment in the circuit.Surge Protector factory
