10 kV Zinc Oxide Surge Arrester - High-Quality Protection from Overvoltage by China Suppliers and Factory
Product Overview
The 10 kV zinc oxide arrester (model 17/50) is a core protective device designed to shield various electrical systems from overvoltage damage. As a professional overvoltage protector, it plays a crucial role in ensuring the service life and operational reliability of key electrical equipment such as transformers, switches, capacitors, and motors.
Its core function is to mitigate the risks posed by atmospheric overvoltage (e.g., caused by lightning strikes), operating overvoltage, and power frequency transient overvoltage (resulting from power system operational anomalies). By participating in the insulation coordination of electrical systems, this arrester effectively maintains the integrity and stable operation of power systems, railway electrification systems, and communication networks.
Product Performance
Excellent Core Material Performance
The core component is zinc oxide resistor sheet, which has outstanding nonlinear volt-ampere characteristics, laying a solid foundation for reliable operation.

Railway Electrification Systems
Safeguards electrical components of railway power supply lines and locomotives, ensuring stable operation of railway transportation.
Communication Systems
Protects communication power supply equipment and signal transmission equipment from overvoltage damage, maintaining the smoothness of communication networks.
Industrial & Commercial Buildings
Suitable for industrial and mining enterprises, high-rise buildings, and other places with 10 kV electrical systems that require overvoltage protection.
Frequently Asked Questions
Q
What is the rated voltage of the 10 kV zinc oxide arrester (model 17/50)?
The arrester is rated for 10 kV systems. The model designation 17/50 refers to its continuous operating voltage of 17 kV and a nominal discharge current rating, making it suitable for standard 10 kV distribution and transmission networks.
Q
What types of overvoltage can this arrester protect against?
This arrester is designed to protect against three main types of overvoltage: atmospheric overvoltage caused by lightning strikes, operating overvoltage generated during switching operations, and power frequency transient overvoltage resulting from abnormal conditions in the power system.
Q
Why is zinc oxide used as the core resistor material?
Zinc oxide (ZnO) resistor sheets exhibit outstanding nonlinear volt-ampere characteristics. Under normal operating voltages, the resistance is extremely high (allowing only microampere-level leakage current), while under overvoltage conditions, resistance drops sharply to allow thousands of amperes to pass — effectively clamping and dissipating the surge energy.
Q
What electrical equipment does this arrester protect?
The 10 kV zinc oxide arrester is used to protect a wide range of electrical equipment including power transformers, circuit breakers, disconnect switches, current and voltage transformers (mutual inductors), generators, capacitors, motors, and power cables within 10 kV electrical systems.
Q
Is this arrester suitable for railway and communication applications?
Yes. The arrester is specifically designed to be compatible with multiple system types. In railway electrification systems, it protects traction power supply lines and locomotive electrical components. In communication systems, it safeguards power supply and signal transmission equipment, ensuring uninterrupted network operation.
Q
Does the arrester affect the normal operation of connected equipment?
No. Under normal operating conditions, the arrester maintains an extremely high resistance state, allowing only a microampere-level current to pass through. This negligible leakage current has no measurable impact on the performance or efficiency of any connected electrical equipment.
