POLE-MOUNTED TRANSFORMERS

Pole-Mounted Transformers for Overhead Distribution Lines

Yuantong builds single-phase and three-phase pole-mounted distribution transformers, including SBH15 amorphous alloy units with low no-load loss. They mount directly on a utility pole and step overhead line voltage down to the low voltage used by homes, farms and small businesses. Every unit is routine-tested before it ships.

CONSTRUCTION & CHARACTERISTICS

How Our Pole-Mounted Transformers Are Built

Pole Mounting

Brackets designed for direct mounting on utility poles.

Sealed Tank

Fully sealed oil-filled tank for long, maintenance-light service outdoors.

Amorphous Core Option

SBH15 units use an amorphous alloy core to cut no-load loss.

Light and Compact

Compact design for easy lifting and installation on the pole.

Weather Protection

Painted tank and outdoor bushings for rain, sun and dust.

Utility Voltages

Built for the primary and secondary voltages of your distribution line.

FAQ

Pole-Mounted Transformer FAQ

What size of pole-mounted transformer do you supply?

Our standard pole-mounted transformers range from 25 to 100 kVA, in single phase or three phase. Send us your line voltage and load for a recommendation.

An amorphous alloy core has much lower no-load loss than silicon steel. Because pole-mounted transformers are energised all day, this lowers the lifetime energy cost of the network.

Yes. We build the secondary voltage to your specification, including 120/240 V split-phase or 0.4 kV.

The minimum order is one unit. Standard ratings typically ship 15–30 days after the order and deposit are confirmed; custom designs depend on the specification.

We design to IEC or GB standards, or to the standard named in your specification. A routine test report is supplied with every unit.
