Product Introduction
The high-speed railway uses a meital-oxide surge arrester with gapped structures, 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.

Product Features
1、Overvoltage Protective Characteristics
When overvoltage occurs in the power system, the lightning arrester can quickly respond, limiting the overvoltage within the tolerable range of the equipment, thereby protecting the electrical equipment and systems of the EMU train from damage.
2、High Mechanical Strength
It is manufactured with high-strength, corrosion-resistant materials and undergoes rigorous mechanical strength testing to ensure stability and reliability under various harsh operating conditions.
3、Strong Resistance to Vibration and Impact
Through reasonable structural design and material selection, its natural frequency and damping ratio are improved, reducing the impact of vibration on the equipment and enhancing its shock resistance.
4、Stable Insulation
Rigorous control over insulation material selection, insulation structure design, and insulation performance testing ensures stable insulation performance of the EMU train lightning arrester.
