Attach 1 - TRANSFORMER SALIENT CHARACTERISTICS.pdf

This document is a technical specification for a 500 KVA three-phase oil-filled transformer. The transformer must feature a radial feed configuration with windings of aluminum or copper if remanufactured, or aluminum if newly manufactured. The primary voltage is specified at 12470/7200-volt DELTA with 15 KV, 200-amp loadbreak bushing wells equipped with 15 KV 200-amp inserts, one on-off loadbreak switch, and Bay-O-Net fuses. The secondary voltage is 208/120-volt WYE with 8-hole spade terminals.

The transformer must include standard operational and safety features: an upper fill plug, drain valve, liquid level gauge, pressure/vacuum gauge, and an automatic pressure relief valve. Additional requirements include grounding provisions, a three-point latching door with padlock provision, and standard ANSI green paint finish. This specification establishes the minimum technical requirements that any offered transformer must meet to be considered compliant with the procurement requirement.
