The 12KV Polymer Lightning Arrester (Model: HY10W-12L) is the only 12kV arrester on the market with IEC 60815 Class IV pollution resistance— tailored for heavily polluted environments (e.g., coastal, industrial, mining zones). It features a ZnO varistor core (10kA discharge current, <1μA leakage) and six alternating large-small silicone sheds (large: Ø116mm, small: Ø95mm), with a 425mm creepage distance (exceeding Class IV requirements). Operating from -40°C to +85°C, it protects 12kV AC systems (7.2kV–12kV) from transient surges.
Large Sheds: Enhance creepage distance and prevent pollutant bridging in heavy-contamination zones (e.g., coastal salt fog, industrial chemical vapors).
Small Sheds: Improve rain/ice resistance and reduce dry-band arcing— a leading cause of arrester failure in wet-polluted areas.
Sintered ZnO blocks with Bi₂O₃ additives ensure <1μA leakage current under normal voltage, reducing power loss and thermal aging.
425mm creepage distance + HTV silicone housing resists salt-fog corrosion, protecting HV switchgear/transformers in coastal substations.
Hermetic design prevents conductive dust ingress, ensuring reliable performance in mining switchrooms (a major pain point for standard arresters).
-40°C to +85°C operating range handles offshore humidity and temperature swings, safeguarding 12kV collector systems for wind turbines.
Rigorous Certification: Passes 1000h salt fog test (IEC 60507), 5000h aging test (115°C), and 20-cycle short-current test (4kA RMS); test reports provided.
Custom Shed/ Grounding: Offers ultra-heavy-pollution shed profiles (ESDD >0.8 mg/cm²) and M10 bolt grounding lug adjustments.
Long-Term Warranty: 8-year warranty + on-site fault diagnosis; designs grounding schemes (Rearth ≤10Ω) for optimal surge dissipation.
