Construction
•
The core and coil shall be vacuum processed to ensure maximum
penetration of insulating fluid into the coil insulation system. While
under vacuum, the windings will be energized to heat the coils and
drive out moisture, and the transformer will be filled with preheated
filtered de-gassed insulating fluid.
•
The core shall be manufactured from burr-free, grain-oriented silicon
steel and shall be precisely stacked to eliminate gaps in the corner
joints.
•
The coil shall be insulated with B-stage, epoxy coated, diamond
pattern, insulating paper, which shall be thermally cured under
pressure to ensure proper bonding of conductor and paper.
•
Coils shall be either aluminum or copper.
•
The tank shall be complete with an anodized aluminum laser engraved nameplate.
This nameplate shall meet Nameplate B per ANSI C57.12.00.
•
Clamp-type tank grounding connections shall be provided for pad
mount distribution transformers in accordance with ANSI C57.12.34.
•
A primary switch shall be provided.
•
Externally-mounted, Distribution Class M.O.V.E. dead-front elbow arrestors shall be
supplied.
