Designed to help suppress radiated electromagnetic interference in airport lighting systems, the StrikeShield lightning-retardant cable is composed of two independent isolated shields. The first layer of metallic tape shield wraps helically around the second layer, which is made up of wires isolated from each other. The magnetic field resists the flow of lightning generated current, allowing it to dissipate without damaging the cable. It can be used in direct burial, conduit, or raceway applications, and it also works for inset and elevated lighting systems for runways and taxiways.
