Airfield Cable, Isolation Transformers & MV Switchgear

The buried and switchroom electrical infrastructure that carries AGL power around the airfield, distinct from the fixtures and the CCR/control layer: series-loop isolation transformers (FAA L-830/L-831), primary series-circuit cable, L-823 connectors and connector kits, secondary cabling, medium-voltage airfield switchgear and distribution, plus the AGL grouts, sealants and fixing compounds that bed inset fittings into the pavement. This is a civil-electrical procurement line specified by loop kVA, insulation class, connector standard and pavement-compatibility, sourced heavily during new-runway construction and rehabilitation, and a large recurring spares category given series-loop transformers fail individually over time.
