10.2 kV MCOV Distribution Arrester
Distribution arresters are critical surge protection devices used in power line construction to safeguard electrical equipment from overvoltage transients caused by lightning strikes or switching operations. Installed on distribution systems (typically 1–38 kV), these arresters divert excess energy safely to the ground, ensuring system reliability and extending equipment life.
Key Features:
- High Energy Absorption: Utilizes zinc oxide (ZnO) varistor blocks for superior surge handling capacity.
- Weather-Resistant Housing: UV-resistant polymer or porcelain insulation ensures long-term durability in harsh environments.
- Compact and Lightweight Design: Simplifies installation and maintenance on poles and substations.
- Creepage and Leakage Control: Optimized shed profiles reduce surface current paths in polluted or wet conditions.
- Fail-Safe Mechanism: Designed to disconnect from the line in the event of internal failure to maintain system safety.
- Standard Compliance: Meets or exceeds ANSI/IEEE C62.11 and IEC 60099-4 standards.
