Introduction

In the field of rail transit, DC arresters and voltage limiting devices are safety protection components used in DC systems: DC arrester it is applied to the power input end of the equipment where it is likely to be struck by lightning: It discharges the lightning energy into the ground to protect the system: DC gapless metal oxide avoids with its unique performance advantages and mature manufacturing technology, lightning arresters have become the necessary overvoltage protection equipment for DC systems in the rail transit field:

The voltage limiting device is used to protect the DC traction power supply system from electric shock and is an important safety protection device for the traction power supply system:
