About this file
This document is a detailed schematic drawing for an ALAMO 150kVA Three Phase Pad Mounted Transformer, specifically designed for electrical power distribution with primary voltage at 12,470V and secondary voltage at 208V. The technical drawing, labeled as Attachment G.6, provides a comprehensive view of the transformer's structural design, including multiple perspective views (side, front, and internal compartment details) and a complete component inventory listing 29 distinct parts such as tank, filling cap, lifting lugs, cabinet lock handle, high and low voltage compartment doors, and various technical instruments like pressure/vacuum gauges and thermometers.
The transformer weighs 3,461 pounds and has specific dimensional measurements across parameters A through H, ranging from 24 to 63 units. The schematic indicates a Yyn0 connection type and includes detailed technical specifications for both high voltage and low voltage compartments. The drawing was created by Jaime Chulco and reviewed by Diego Moyolema on 31-05-2023, suggesting this is a recent technical specification for electrical infrastructure equipment, likely part of a procurement or infrastructure upgrade project for an electrical utility or large-scale infrastructure development.
