Drawing_Schematic_LCOM D_ALW-D2-05_1.jpg

The image is an electrical schematic diagram labeled ALW-D2-05, depicting a lightning protection circuit design. The diagram shows a complex arrangement with differential gas tubes (GT), surge resistors (R), and a diode clamp array, connected between a line side and equipment side, with an earth ground connection. Key components include multiple resistors, gas tubes, and a grounding mechanism designed to protect electrical equipment from lightning-induced surges and voltage spikes.

The schematic is associated with a federal solicitation (142082-25-0133) by the National Oceanic and Atmospheric Administration (NOAA) for L-COM Lightning Protection Units at the National Logistics Support Center in Grandview, MO. The procurement is a firm fixed-price contract with the intent to award to the most responsive and responsible quoter providing best value. Contractors must be registered in the System for Award Management (SAM) to be eligible for award, and must obtain a unique entity identifier through SAM.gov.
