About this file
This document is an Amendment 1 Revised Brand Name or Equal Specifications for a 150 KVA 3-Phase Transformer with a detailed technical specification. The transformer is a liquid-filled, pole-mounted unit with a three-phase configuration, designed for 13800V primary voltage and 208Y/120V secondary voltage. Key technical specifications include a 5-position tap changer, copper windings, mineral oil non-PCB fluid, and compliance with DOE 2016 efficiency standards and multiple ANSI/IEEE standards.
The transformer features comprehensive technical requirements such as a 65°C temperature rise, ONAN cooling class, porcelain high voltage bushings, and NEMA 4-hole drilled spade terminals. It undergoes extensive factory testing including winding resistance, insulation resistance, voltage ratio error, short-circuit impedance, and multiple other quality assurance tests. The unit is UL approved, has 99% efficiency at 50% of nameplate base kVA, and includes external labeling with a stainless steel riveted nameplate. The specifications are part of solicitation 140R2025Q0088 and provide detailed performance and technical requirements for potential suppliers.
