The
UltraCast Cast Coil transformer is cast in epoxy on a mold under vacuum,
for a completely sealed rigid coil structure.
The design provides numerous additional benefits over standard oil
filled or VPI transformers, including superior short circuit strength,
resilience from adverse environments, virtually zero maintenance and high
Basic Impulse Insulation Level (BIL) capabilities.
The UltraCast Cast Coil transformer has the following
features:

| Semiconductors |
|
Each
thyristor is mounted on silver plated deep hole drilled copper heat sinks
and cooled from both sides to efficiently remove the heat generated in the
devices. By operating the
thyristors at a conservative level, relative to the rating of the device
and by removing the heat generated in an efficient manner, the junction
temperature of the device may be maintained to a conservative level
ensuring long-term reliability. N-1
semi-conductor redundancy is available. |

|
| Cabinet |
|
The cabinet is
heavy-duty industrial steel mill type design providing added protection
from the mill environment. Heavy
welded angle iron base, combined with pre-formed structural members,
provide sturdy construction and attractive appearance.
Acid resistant paint over a primer is used on all structures and
panels, and all bolted panels are removable for component inspection.
