125 KVA 12470V Medium Voltage Transformers ANSI IEEE Single Phase Pad Transformer
Leilang Electric 125 kVA single-phase pad-mounted transformer is a heavy-duty utility distribution solution engineered for 12470V grids, built to strict ANSI/IEEE C57 standards and featuring a fully sealed structure for maximum reliability and minimal maintenance. This unit safely steps down 12470GrdY/7200V primary voltage to standard 120/240V secondary power, with full compliance to North American utility codes, DOE 2016 efficiency, and CSA requirements. Its fully sealed oil compartment prevents dust, moisture, and contamination, ensuring stable performance in harsh outdoor environments. With UL/cUL certification, copper windings, and a compartmental-type II dead-front design, it delivers long service life, strong safety, and consistent power for residential, commercial, and industrial applications.
