Construction and Insulation
The core and coil are encapsulated in a polyurethane resin. This
tough material has excellent electrical and mechanical properties
over a wide temperature range and is UV resistant for outdoor use.
Core and Coils
The core is made from high quality grain oriented silicon steel,
annealed under rigidly controlled factory conditions. The secondary
winding is made of heavy enameled copper wire. The secondary
windings are evenly distributed around the core for maximum
accuracy and resistance to stray fields from adjacent conductors.
Terminals
Secondary terminals are tin plated brass, compression type with a
0.275” diameter cross-hole for wiring and a 1/4-28 clamp screw. A
shorting device is provided and interlocked to the terminal cover.
The terminal cover is made of a clear plastic. Provision is made for
sealing the cover.
Polarity
Primary and secondary polarity marks are white.
Conduit Attachment
available. It is suitable for outdoor applications. Box and cover has a
gasket and four sealable thumbscrews.
Nameplate
The nameplate is laser engraved aluminum. It is attached to the
top of the unit and has provision for attaching the user’s
identifying tag. The nominal current rating is marked on both
faces of the unit in large numerals.
Baseplate and Mounting
The transformer can be mounted in any position. Optional
stainless-steel mounting feet are available, they are attached to
the transformer with two bolts. If baseplate is not supplied,
mounting hardware to be min (2) 1/2 bolts with
(4) USS flat washers. Torque value not to exceed 35 ft. lbs.
Maintenance
These transformers require no maintenance, other than
occasional cleaning, if installed where air contamination is severe.
