Airport Lighting Cable, officially designated as FAA L-824, is a specialized 5kV-rated single-conductor cable. Unlike standard wire, it is engineered for series lighting circuits where a Constant Current Regulator (CCR) pushes power through a continuous loop that guide aircraft on runways and taxiways. It features rugged insulation (typically Type B EPR or Type C XLPE) designed to withstand direct burial and constant exposure to jet fuel, de-icing fluids, and hydraulic oils common in airfield environments.
#8 AWG is the industry-standard size for FAA L-824 primary series circuits. Its primary applications include:
Runway Edge Lighting: Powering the white and yellow lights that define runway boundaries.
Taxiway Edge & Centerline: Illuminating blue taxiway edge lights and green centerline navigation paths.
Navigational Aids (NAVAIDs): Providing high-voltage power to critical landing systems such as PAPI (Precision Approach Path Indicators) and VASI (Visual Approach Slope Indicators).
Approach Lighting Systems (ALS): Supplying the sequence flashers and steady-burn lights that guide aircraft during their final descent.
While L-824 cable is frequently installed in underground conduit or duct banks, it is officially rated for direct burial. However, for direct burial applications, it is critical to use a sand-padded trench and ensure there are no sharp rocks that could compromise the insulation during backfilling.
Yes. Our L-824 Type C cable is engineered explicitly for the harsh "airside" environment of commercial and military airports. The advanced XLPE jacket is completely impervious to degradation from leaked aviation jet fuel, aircraft hydraulic fluids, heavy engine oils, and aggressive runway de-icing chemicals that naturally leach into the surrounding soil.
FAA Advisory Circular 150/5345-7F regulates materials used in federal airfield lighting systems. An L-824 certification guarantees the wire meets strict baseline testing standards for dielectric strength, thermal longevity, and chemical exposure. Installing non-certified wire in an airport grid is a major regulatory violation and puts critical aviation landing infrastructure at risk of sudden failure.
Type B: Typically insulated with EPDM (Ethylene Propylene Diene Monomer) or similar rubber-like compounds. It is known for its extreme flexibility and ease of handling in cold weather.
Type C: Features XLPE (Cross-Linked Polyethylene) insulation. Type C is generally more rigid but offers superior resistance to heat and chemical degradation, making it a favorite for long-term durability in underground conduits.
Yes, all L-824 cables stocked by Wire America are sunlight (UV) resistant. While they are primarily used underground, they are often exposed at connection points or in surface-mounted taxiway sign housings, and the insulation is designed not to crack or degrade under UV exposure.
