They're often mounted high in the air on poles, for safety. 4kV to 35kV) to consumption levels (120/240V in North America, 230/400V in Europe). Other more esoteric phenomenon that also result in elevated voltages on normally non-energized surfaces, are also referred to as “stray voltage. Its core function is to step down medium voltage (e. OMEX Industries – Transformers for the Ones Powering America. Feb 5, 2026 · Its primary function is stepping down the voltage from distribution levels (2. To estimate the current in amps, you need to know the transformer’s power rating and the output voltage. A telephone pole transformer is a type of distribution transformer mounted on utility poles to step down medium voltage electricity (typically 11kV or 22kV) to lower voltages (usually 230V/400V) suitable for residential and small commercial use. Buy Electrical Supplies Online at Platt Electric Supply. Wholesale electrical, industrial, lighting, tools, control and automation products. 1、What Is a Pole-Mounted Transformer? Pole-mounted transformers are essential components in modern power distribution networks. , 11kV – 33kV) from the distribution lines to a usable level (e. Photo by Robert DeDeaux courtesy of US Army Corps of Engineers and DVIDS. We are a value added wholesale distribution company that supplies products and services to the electrical, construction, commercial, industrial, utility and datacomm markets. ” Aug 5, 2023 · Photos: Step-down: distribution transformers like these convert high-voltage power to lower voltages used in homes, so they're examples of step-down transformers. The transformer on a telephone pole steps down the voltage from the high-voltage distribution lines to a much lower, safer voltage (typically 120/240 volts in the United States) that homes and businesses can use. Jul 23, 2025 · A power pole transformer (also called a pole distribution transformer or electric pole transformer) is a distribution transformer mounted on a utility pole. Typically, residential pole-mounted transformers range from 10 to 167 kVA (kilovolt-amperes), with common ratings being 25, 50, or 75 kVA. Core Function: It steps down electricity from high-voltage transmission lines (typically thousands of volts) to safer, usable voltages (120V/240V or regional equivalents). , 120/240V) for homes or businesses. CAD blocks and files can be downloaded in the formats DWG, RFA, IPT, F3D. This transformation makes electricity compatible with everyday appliances and machinery. We stocks UL/CSA Standard Transformers and can help you with your Transformer project Needs from standard dry type Transformers to various oil filled Transformers. Their primary function is to step down high-voltage electricity from overhead transmission lines to lower voltages suitable for . Pole mounted transformers step down high voltage electricity to safe distribution levels for homes and businesses. As their name suggests, these transformers are installed high above the ground, typically mounted on wooden or concrete utility poles. The term "stray voltage" is commonly used for all unwanted electrical leakage, by both the general public and many electrical utility professionals. 3 kV to about 35 kV depending on local distribution practice and standards, often 11 kV (50 Hz systems) and 13. REAP helps families in need pay their utility bills throughout the year and educates them on energy-saving conservation measures to help them save money. 8 kV (60 Hz systems) are used, but many other voltages are standard.
