EMU Lightning Arrester
The high-speed railway uses a gapless metal oxide lightning arrester, primarily applied in high-speed railway systems. The high-speed rail lightning arrester exhibits excellent nonlinear volt-ampere characteristics, presenting a high-resistance insulation state under normal operating voltage. When subjected to lightning or switching overvoltage surges, it enters a low-resistance state, rapidly discharging surge currents into the ground, protecting parallel electrical equipment from damage and ensuring insulation safety.
