What is a surge? Surges or transients are short duration increases in voltage measured between conductors. These potentially harmful voltages can reach up to 6000 Volts from direct lightning strikes or secondary effects.
What is SPD? Surge Protection Devices (SPD) are designed to limit transient overvoltages and divert current waves to earth, protecting electrical installations and control gear.
Wenzhou Britec Electric Co.,Ltd. was founded in 2003 and specializes in developing high-quality surge arresters including AC surge protectors, DC protection devices, data surge protection, and LED lightning protection systems.
