Lightning rods with bases protect these cultural assets by diverting strikes away from the building. It also ensures that the surrounding electrical systems remain protected. Many historic structures are fitted with lightning protection systems to ensure they remain undamaged during severe weather.

Product Specifications and Features of Lightning Rods with Bases

Technical Specifications

• Rod Material

  Lightning rods with bases are primarily made of copper or zinc-plated steel. Both materials have excellent electrical conductivity, ensuring efficient lightning dissipation. Copper rods typically last longer, especially in corrosive environments.

• Conical Section

  The conical section protected by a lightning rod is the area where lightning is likely to strike. The aim of the rod is to attract the strike and direct it safely into the ground. A longer conical section provides a wider protective range.

• Base Design

  The base of a lightning rod is usually fabricated from tough materials like galvanized steel or aluminum. It ensures stability and corrosion resistance. Most bases have mounting provisions for secure attachment to structures.

• Height

  A lightning rod's height affects its ability to attract lightning. Commonly used rods are between 8 to 10 feet long. Taller rods provide additional protection in areas with extreme lightning activity.

• Compliance Standards

  These lighning rods with bases usually conform to international standards like the NFPA 780 and UL 96. These standards mean that the rods meet minimum requirements for electrical safety and protection against lightning.

Installation Guidelines

• Mounting Base

  The bases for the lightning rods fabricated from either aluminum or galvanized steel are mounted securely onto the rooftop or the uppermost point of a structure. It ensures the rod remains stable.

• Grounding System

  A proper grounding system is critical. The lightning rod should be connected to an underground metal wire or pipe. This helps dissipate electrical energy safely into the ground.

• Multi-Rod Installation

  If the structure is large, consider several lightning rods. Space them out evenly and connect them with horizontal conductors. This way, the whole area will receive protection.

• Bonding

  Ensure all metal parts of the structure are bonded together. This helps prevent side flashes that could jump between unbonded metal surfaces during a lightning strike.

Maintenance and Repair

• Visual Inspections

  Conducting frequent visual checks allows for the validation of the lightning rod's physical integrity and of its base as well. Look for corrosion, structural damage, or any discoloration due to wear. Also, examine cables connected to the rod for signs of fraying or deterioration.
