Product Introduction

Product Overview

Yawei Electric proudly presents the 34.5 kV industrial-grade pad-mounted distribution transformer, engineered for modern cities, industrial parks, commercial complexes, infrastructure projects, and renewable energy applications. This pad-mounted distribution transformer safely steps down medium-voltage primary power to low-voltage secondary power, ensuring stable, reliable electricity supply for utility, industrial, and commercial networks.

Designed with a utility-grade concept, the 34.5 kV pad-mounted transformer is widely used in utility feeder systems, industrial plants, commercial developments, data centers, and renewable energy projects across North America, Europe, South America, Central Asia, Africa, and Australia. Its outdoor ground-mounted design, oil-immersed insulation system, and heavy-duty enclosure allow long-term reliable operation even under harsh environmental conditions.

Yawei Electric offers factory-direct manufacturing, customized engineering, and bulk supply, supporting international power distribution projects with OEM production and large-scale deployment.
