Small distribution transformers installed on overhead circuits are commonly referred to as which transformers?

• A. network
• B. pad-mount
• C. pole-type
• D. submersible

Answer: (C)

Pole-type transformers are used on overhead distribution lines; they’re mounted on utility poles and step the high distribution voltage down to service voltage right at the pole. This arrangement keeps the equipment accessible to crews and avoids routing underground. Pad-mount transformers sit on a ground pad and are used where lines are underground or space is limited, submersible transformers are designed for underground or submerged installations, and network transformers are used in specific network distribution configurations for high reliability. So the small distribution transformers on overhead circuits are described as pole-type transformers.
