Key Selling Points
  • High-Performance MOA Core: Utilizes premium non-linear Zinc Oxide Varistors (MOA) for superior over-voltage protection and steep-current impulse response.
  • Excellent Hydrophobicity: The red silicone rubber housing provides outstanding water-repelling properties, preventing surface tracking even in heavy rain or fog.
  • Superior Sealing: Engineered with a specialized triple-sealing structure to ensure the unit remains 100% moisture-proof throughout its service life.
  • Full Range Coverage: Available for all systems from 3kV up to 220kV, suitable for both distribution lines and high-voltage substations.
  • IEC 60099-4 Compliant: Manufactured and tested to meet international standards for reliability in extreme electrical environments.

Product Description

Our YH Series Polymer Housed Zinc Oxide Surge Arresters (MOA) are premium overvoltage protection devices designed for power distribution lines, transformers, and high-voltage substations. Engineered with high-quality non-linear zinc oxide varistors, these arresters effectively suppress lightning surges, switching overvoltages, and transient power frequency overvoltages, safeguarding critical electrical equipment from damage. The durable red silicone rubber housing offers exceptional hydrophobicity, UV resistance, and anti-pollution performance, making it ideal for harsh outdoor environments including coastal areas, high-humidity regions, and industrial zones. With a full voltage range covering 3kV to 220kV, the YH Series caters to both distribution-level and substation-level applications. Its robust triple-sealing structure ensures long-term moisture-proof reliability, while the explosion-proof design guarantees operational safety. Fully compliant with IEC 60099-4 and GB/T 11032 international standards, these arresters deliver consistent, maintenance-free performance for decades.
