Made by Robbins Lightning, it emphasizes high conductivity and resistance to environmental wear. The braided construction helps resist fatigue and corrosion, contributing to stable lightning protection paths over time, making it a solid option for grounded connections in residential to light commercial installations.
Buying Guide: Key Considerations for Lightning Protection Cable Clamps
Material and corrosion resistance: Look for aluminum, copper, or brass clamps designed for outdoor use, with corrosion-resistant finishes or plating to withstand exposure to weather and salt air.
Conductor compatibility: Verify that the clamp supports your conductor size and type (AWG ranges, aluminum vs copper) and whether the clamp is suited for direct burial or rooftop mounting.
Installation method: Drilled vs non-drilled options, adhesive mounting vs mechanical fasteners, and ease of installation (tool requirements, required hardware) impact project timelines and safety.
Electrical performance: Consider clamps with UL approval, IEC-aligned discharge capabilities, and adequate surface contact area to ensure low resistance and reliable bonding.
Durability and suitability for environment: For rooflines or PV installations, ensure clamps resist wind, temperature fluctuations, and exposure to UV and moisture.
Pack size and scalability: Multi-pack options help cover multiple grounding routes or future expansions, reducing the need for repeat purchases.
