Product Description
167 kVA Single Phase Pad Mounted Transformer | 12.47V, Multiple Safety Protections, Low TCO
Product Overview
Leilang Electric 167 kVA single-phase pad-mounted transformer is a high-capacity utility-grade power distribution solution purpose-built for North American 12.47kV grid systems, delivering industry-leading safety and exceptional long-term value. Designed to step down 12470GrdY/7200V primary voltage to standard 120/240V secondary power, this unit features a comprehensive multi-layer safety protection system that eliminates operational risks and ensures reliable power delivery in high-demand environments.
Engineered for ultra-low total cost of ownership (TCO), it achieves an impressive 99.33% overall efficiency with only 425W no-load loss and 1733W load loss, significantly reducing energy expenses over its 25+ year service life. Built with a robust Compartmental-Type II dead-front enclosure and 100% high-purity copper windings, it requires minimal maintenance and exhibits exceptional durability in extreme outdoor conditions. Fully certified to ANSI/IEEE C57, CSA and DOE 2016 standards, it is ideal for high-density residential communities, medium-sized commercial centers and light industrial facilities.
