Product Introduction
Overview
• A Pole Mounted Transformer is a type of distribution transformer mounted on utility poles to step down high-voltage electricity from overhead lines to lower voltages suitable for residential, rural, and light commercial use across the United States.
Application
• These compact transformers play a critical role in the electrical distribution network by converting medium-voltage power to common service voltages like 120/240 V that safely power homes, farms, businesses, and street lighting. Their elevated design keeps them above ground-level hazards such as flooding and minimizes space usage, making them ideal for suburban and rural grid infrastructure where underground distribution is impractical.
Advantages
• Pole mounted transformers can be single-phase or three-phase units depending on load requirements, and they are valued for cost-effective installation, easy access for maintenance, and compatibility with existing overhead systems. By efficiently managing voltage conversion and distribution, these transformers help ensure reliable, safe, and continuous electric service throughout communities nationwide.
