Buying Guide: How To Choose The Right Lightning Arrestor
- Material and durability: Porcelain bodies resist corrosion and aging better in outdoor environments. Metal components offer strength but may require extra coatings or maintenance.
- Completeness of kit: Look for arrestors that come with grounding clamps, connection clips, screws, and grounding electrodes for faster, cleaner installations.
- Compatibility: Ensure the arrestor is compatible with your energizer and fencing wire size. Cross-brand compatibility can reduce the number of separate parts you need.
- Grounding quality: Proper grounding is essential. In sandy or dry soils, consider additional ground rods and a robust ground clamp.
- Ease of installation: Front-end accessories and clearly labeled wiring instructions save time and reduce errors during setup.
- Protection scope: Decide if you want a single-point protection or a multi-point strategy to cover multiple fence segments.
- Weather exposure: Outdoor installations should favor rust-resistant materials and sealed components to extend life in harsh conditions.
Frequently Asked Questions
- What is a lightning arrestor for electric fences? It is a device that diverts or shunts surge energy away from the fence energizer to prevent damage and keep fences energized after a strike.
- Do I need grounding for an arrestor? Yes. Proper grounding helps dissipate surge energy and protects the entire fencing system.
- Can I use any arrestor with my energizer? Check compatibility with your energizer model and wire gauge; some kits are universal, others are brand-specific.
- How many arrestors should I install? Install at least one arrestor near the energizer, and add additional arrestors for long or multi-section fences or high-surge areas.
- How do I know if my fence is protected? If a surge occurs, your energizer should remain operational and the fence should stay energized; inspection after storms confirms continued function.
- Are porcelain arrestors better than metal? Porcelain resists cracking and corrosion, offering stable electrical performance; metal parts are strong but may corrode without proper coating.
