Silicone Polymer Distribution Arrester

The Silicone Polymer Distribution Arrester is a high-performance surge protection device designed for medium-voltage power distribution systems. It protects electrical equipment by safely diverting overvoltage surges caused by lightning strikes, switching operations, or faults to ground. Engineered with a robust silicone rubber housing and zinc oxide (ZnO) varistors, this arrester delivers superior reliability, hydrophobicity, and long-term outdoor durability.

Key Features:

  • Silicone Polymer Housing: Offers excellent UV resistance, hydrophobicity, and resistance to weathering and tracking.
  • Zinc Oxide Varistors: Provides high surge absorption capacity with low residual voltage and fast response time.
  • Lightweight and Compact Design: Easier handling and installation on distribution poles or equipment bushings.
  • Sealed Construction: Prevents moisture ingress, ensuring long service life and stable performance.
  • High Energy Handling Capability: Withstands multiple high-energy surges with minimal degradation.
  • Corrosion-Resistant Hardware: Stainless steel fittings ensure long-term performance in harsh environments.
  • Compliance: Meets or exceeds IEEE C62.11 and IEC 60099–4 standards for surge arresters.
