• UHV-Specific Design：Rated exclusively for 750kV to 1000kV systems, with electrical parameters optimized to handle the extreme voltage stresses and high energy levels unique to ultra-high voltage transmission, ensuring compatibility with UHV grid equipment.

• Extreme Energy Absorption：Equipped with high-density MOVs capable of absorbing enormous surge energy from catastrophic events (e.g., direct lightning on UHV lines or substation faults), preventing insulation breakdown in high-value UHV components.

• Ultra-Fast Response：Microsecond-scale reaction to transient overvoltages minimizes voltage overshoot, critical for protecting UHV transformers and cables—where even short-duration spikes can cause irreversible damage.

• Enhanced Environmental Resistance：Housings (advanced composite or porcelain) offer superior durability against harsh conditions: UV radiation, extreme temperature fluctuations, heavy pollution, and coastal humidity, ensuring reliability in diverse UHV deployment environments (e.g., deserts, mountainous regions).

• Low Steady-State Leakage：Minimal leakage current during normal operation reduces energy loss and heat buildup, maintaining efficiency in UHV grids where even small losses can impact large-scale power transmission.

• Mechanical Robustness：Structurally reinforced to withstand high wind loads, vibration, and installation stresses in UHV substations, ensuring stability in large-scale infrastructure with heavy equipment and long operational cycles.

• Compliance with UHV Standards：Meets stringent international standards (e.g., IEC 60099-4, GB/T 11032 for UHV) and undergoes rigorous testing for impulse withstand, thermal stability, and long-term performance, guaranteeing compatibility with global UHV networks.

• Integration with UHV Monitoring：Many models feature built-in sensors for real-time monitoring of leakage current and temperature, enabling integration with UHV grid management systems for predictive maintenance and early fault detection.
