Description
ABB Distribution Transformers manufactures
single-phase, oil type small distribution transformers for pole mounting. These represent
an economical option for certain networks.
They are suitable for serving residential overhead distribution loads, as well as for lighting,
commercial loads, industrial and diversified
power applications. ABB’s core design provides

1. Primary Termination
• Cover-mounted high voltage porcelain
bushing(s) with spin top terminal.
• Side-wall mounted high voltage
porcelain bushing(s) with spin top
terminal (Standard on all 4800 volts
and below).
• Primary current limiting backup fuse.
2. Secondary Termination
• Low voltage porcelain bushings with
NEMA spade terminals (Standard on
all units 167 kVA and above).
3. Primary Switching
• Externally-operated tap changer.
• Externally-operated dual voltage
switch or internal terminal board.
4. Overcurrent Protection
• Internally-mounted current limiting
fuse in series with protective link.
5. Contact the division for voltages and
dimensions on 666 through 833 kVA.
Optional Accessories
1. High voltage bushings are of two types
and are made of wet process porcelain:
• Speed wrench operable eyebolt
bushing for cover mounting.
• Spin-top bushings for either cover or
side-wall mount.
2. Tap changers compensate for small
voltage variations along the distribution
system. The externally-operated tap
changer is a single-phase, five-position
design for de-energized operation.
3. A dual voltage switch permits use of the
same transformer on distribution
systems with different system voltages.
4. The CSP® protection package consists
of four related components that work
together to provide complete selfcontained protection against surge
currents, short circuits and overloads:
