The YH10 series represents our premium line of 10kA metal oxide surge arresters, designed to safeguard medium-voltage distribution networks (3kV to 36kV) from lightning and switching overvoltages. While sharing the same high-performance ZnO varistor core, this series offers three distinct structural designs to meet specific installation environments and utility standards worldwide.

YH10W (Standard Series): The classic distribution design with high-strength stainless steel terminals. Ideal for general overhead line protection and transformer mounting.
YH10C (Cap Series): Equipped with a Silicone Rain Cap / Protective Cover. This design prevents moisture accumulation and bird-related flashovers at the top terminal, making it perfect for high-rainfall or coastal areas.
YHJ (Sharp/Pointed Series): Features a specialized pointed top terminal design. Engineered for specific utility connection requirements and to reduce snow/debris buildup on the apex.

Corrosion & Leakage: Our high-grade silicone rubber housing is hydrophobic and UV-resistant, preventing “tracking” and erosion even in salt-spray environments.
Wildlife Protection (YH10C): The integrated cap significantly reduces outages caused by birds or small animals coming into contact with live terminals.
Voltage Stability: Precision-manufactured ZnO varistors ensure a fast response to surges and low residual voltage, extending the life of your transformers.
Easy Installation: Standardized NEMA mounting brackets and flexible terminal options ensure a “drop-in” replacement for existing infrastructure.
- Customization: We support customization for Creepage Distance (e.g., 31mm/kV for heavy pollution) and terminal thread sizes (M10, M12, etc.).
FAQ
Q: Why should I choose the YH10C model with the Cap? A: The YH10C is highly recommended for tropical areas or regions with frequent bird activity. The cap provides an extra layer of insulation at the most vulnerable point (the top terminal).
Q: Are these arresters compliant with IEC 60099-4? A: Absolutely. All YH10W, YH10C, and YHJ models are designed and tested to meet the rigorous standards of IEC 60099-4 and IEEE/ANSI.
Q: Do you provide the insulating bracket and disconnector? A: Yes, each unit can be supplied with a high-strength insulating bracket and a reliable earth-end disconnector (optional) to simplify maintenance.
