Electric Transformer Types

Transformers are generally categorized into single-phase and three-phase types. Within each category, you'll find a variety
of specialized transformers, including step-up, oil field, dry-type, and pad-mounted models. Pad-mounted transformers, which are
installed at ground level, are typically housed in secure, tamper-resistant cabinets. In contrast, pole-mounted transformers
are elevated on utility poles and mainly serve to reduce high distribution voltages to levels safe for residential and small business use.

Dry Type Transformers

Utilizes air instead of liquid coolant to regulate temperature, ensuring a safer and more environmentally friendly solution. Ideal for indoor environments where safety is a top priority.

Oil Filled Transformers

The core and windings are submerged in insulating oil, which serves as both a coolant and an electrical insulator, ensuring efficient heat dissipation and protection for internal components.

Padmount Transformers

Enclosed in a durable metal cabinet and securely ground-mounted, these units are commonly installed in residential neighborhoods and commercial complexes to ensure safe and reliable power distribution.

Polemount Transformers

Pole-mount transformers are installed on utility poles to efficiently reduce high-voltage electricity from distribution lines to a safe, usable level for homes and small businesses.

Step Up/Down Transformers

Step-up and step-down transformers adjust voltage levels by either increasing (step-up) or decreasing (step-down) the electrical voltage. These transformers play a crucial role in ensuring efficient power transmission over long distances and adapting voltage to meet specific application requirements.

Substation Transformers

Often referred to as "Sub-type" transformers, these units step down voltage for residential and commercial use. They play a crucial role in distributing electrical power while ensuring the correct voltage levels for various applications. Commonly located behind fences in transformer distribution yards.
