Receiving & Inspection
Lifting Procedures
WARNING
Failure to follow lifting procedures can result in
death, serious injury, or damage the transformer
and enclosure.
Installation, Operation, and Maintenance Guide - Cast Resin Transformers
Before any equipment is off-loaded, transformers should first
be inspected for correctness of shipping information. Confirm
that the identifying part number on the nameplate of the
transformer matches the packing list and Bill of Lading.
Inspect the transformers immediately upon receipt for evidence
of damage or indication of rough handling that may have been
caused during shipment.
Examination should be made before removing transformer
from shipping vehicles. Inspection should also be made for
any evidence of water or other contaminants that may have
entered the transformer during transit. A claim should be
filed with the carrier at once and the manufacturer should
be notified.
Ventilated dry-type transformers are shipped either completely
assembled in a sheet metal enclosure or as a core and coil
assembly with or without a separate enclosure. All parts and
components are wrapped in clear plastic sheets and covered
with a shipping tarpaulin. Drawings may also accompany the
shipment in a separate package that detail assembly if required.
Once the transformer has been received, remove the covers
or panels and proceed with an internal inspection for any
evidence of damaged or displaced parts, loose or broken
connections, damaged terminal boards, dirt or foreign materials
and for the presence of any water or moisture. If any damage
is evident, contact the transformer manufacturer or your
representative immediately.
- Do not lift transformer by the enclosure.
- Do not lift transformer with shipping hooks.
- Do not lift transformer from beneath the enclosure.
- Do not jerk, lift to avoid mechanical stresses.
- Do not push, drag or pull the transformer directly on
the floor unless it is supplied with the skid base.
Lifting provisions are provided on all dry-type transformers.
Lifting provision can be 2 or 4 of 5/8" (16 mm) or 3/4" (19
mm) shouldered eye bolts or a pair of lifting angles (see figure
1) based on the total weight of transformer. Shouldered eye
bolts are used if the unit weight is less than 15,000 lbs (6,804
kgs). Lifting angles are used if the transformer weight is
15,000 lbs (6,804 kgs) and greater. Use of slings for an angular
lift is strongly recommended.
