JAU-0C

Construction and Insulation

The core and coil are enclosed in a case molded with GE Noryl
thermoplastic PPO resin. This material has excellent electrical and
mechanical properties over a wide temperature range, low water
absorption and is flame resistant .

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 on Model JAI-0C are No. 8-32 brass studs with
one flat washer and one lock-washer and a regular nut. Model JAU­0C has 24” flexible leads of #16 stranded wire.

Polarity

The H1 polarity mark is molded into the case, at the side of the
window on one face. The X1, X2 polarity marks are also molded into
the case adjacent to the secondary terminals. On Model JAU-0C,
the polarity X1 lead is white and the non- polarity X2 lead is black.

JAI-0C

Primary Conductor

These units are designed to be placed over an insulated cable
which forms the primary winding.

Nameplates

The nameplate is a polyester label attached to the side of the
transformer.

Mounting

The transformer can be mounted in any position. And, may be
suspended from the bus-bar or cable.

Maintenance

These transformers require no maintenance, other than
occasional cleaning, if installed where air contamination is severe.
