Description:
Arrester is a kind of overvoltage protector mainly applied for the protechtion of various electrical appliances (such as transformer, switch, capacitor, trap, mutual inductor, generator, motor and power cable etc.) in power system, railway electrification system and communication system from being damaged by atmosphere overvoltage, operation overvoltage and power frequency temporary overvoltage etc.
Advantage:
1. The low weight facilitates installation and permits erection in limited spaces and at almost all angles.
2. No continuous current and low current impulse residual voltage.
3. Excellent pollution and short circuit performance.
4. Safe to touch when energised by accident.
5. Stable U-I characteristics,even after multiple strikes.
6. Resistant to UV,ozone,chemicals,mechanical abuse.
7. Fully qualified following IEC60099-4.
