Frequently Asked Questions
Q
What is the primary function of the 10 kV zinc oxide arrester (model 17/50)?
The primary function of this arrester is to protect electrical equipment from overvoltage damage. It mitigates risks from atmospheric overvoltage (such as lightning strikes), operating overvoltage, and power frequency transient overvoltage, ensuring the safe and stable operation of power systems, railway electrification systems, and communication networks.
Q
What makes zinc oxide resistor sheets superior as a core material?
Zinc oxide resistor sheets exhibit outstanding nonlinear volt-ampere characteristics.
