Product Introduction

Product Overview

The 34.5 kV pole mounted distribution transformer is a utility-grade, oil-immersed single phase transformer specifically engineered for overhead power distribution systems. Designed for installation on utility poles, this transformer plays a critical role in stepping down medium voltage to safe and usable low voltage for end users.

Widely used across residential neighborhoods, rural electrification projects, light commercial facilities, and utility grid expansion programs, the 34.5 kV pole mounted transformer is one of the most commonly specified capacities in overhead distribution networks. With primary voltage options of 34.5kV and a standard 240/480V secondary output, it fully complies with North American and international utility voltage standards.

Manufactured for long-term outdoor operation, this pole mounted distribution transformer delivers high efficiency, stable voltage regulation, and excellent environmental resistance, making it ideal for utility companies, EPC contractors, and electrical distributors worldwide.
