Densimet Heavy Metal High Density Tungsten Alloy Screw for Air Terminations
Air terminations provide a critical role in the lightning protection system, capturing the fullness of the lightning strike current and channelling this current safely to the conductor network to protect buildings and substations.
Furse air termination products are specifically designed to provide highly effective protection against the risks and consequences of a direct lightning strike.
Complete protection against lightning strikes with Furse air termination.
Furse air rods are manufactured from highly-conductive, hard-drawn copper or aluminium, and provide an excellent, durable strike point for lightning - the comprehensive range of air rod bases, conductor fasteners and earth clamps are manufactured from high quality copper or aluminium alloys, ensuring that a high level of conductivity is maintained throughout the air termination system. It also ensures these components are robust enough to last a significant number of years on exposed roof lines.
All these components link together with copper or aluminium conductors, which provide the low resistance path for lightning current - from strike point, safely to earth.
