TRANSPORTATION
Prior to shipment, the SHV switchgear under
goes careful factory inspection and crating. Each
crate is plainly marked at convenient places with
crate number and position. When size or other
reasons make it necessary to divide the equipment
for shipment, the unit number of the particular
equipment enclosed is also marked on the crate,
along with its weight. The circuit breakers are
shipped in individual crates.
Immediately upon receipt of the switchgear, ex
amine for any damage or loss sustained during
transportation. Check the contents again_st the
packing list before discarding any packing material.
If there is any shortage notify the nearest 1-T-E
Circuit Breaker Company representative at once.
The
1-T-E
Circuit Breaker Company is not re
sponsible for damage after delivery
of
shipment
to the carrier. However, if the company is notified
of such claims, it will furnish forms to facilitate
securing any adjustments. If damage to the ship
ment indicates rough handling, claim for damage
should be filed at once with the carrier and the
I-T-E Circuit Breaker Company promptly notified.
The switchgear housings are crated and shipped
in groups of one to six units. Each group is pro
vided with heavy wooden skids. The remainder is
crated for protection. Unloading and handling at
the site is usually done by placing rollers under
the skid. To avoid distortion to the switchgear, any
force to move the structures should be applied
to the skid by means of crowbar, block and tackle,
crane, etc.
STORAGE
Remove crating from the switchgear units, but
leave each group on its skid for subsequent mov
ing. Uncrate circuit breakers and accessories.
Observe the following precautions:
1. Check for missing or damaged parts.
2. Store in clean, dry place.
3. Cover parts susceptible to rust with heavy oil
or grease.
4.
Cover with heavy wrapping paper to keep
dirt or dripping water from entering. Dirt or mois
ture may foul working parts or deteriorate contacts
and insulation.
5. If the switchboard is to be stored for any
length of time, or in any place where dampness
may be present, then heaters should be ..:sed to
keep the switchboard dry until it is placed in serv
ice. When outdoor switchboards equipped with
heaters are stored, the power source for the
heaters should be brought to the load terminals of
the ET thermal circuit breaker or cutout device
which controls the heater circuits.
UNLOADING AND HANDLING
The following is a recommended method for
unloading and handling type 5HV metal-clad
switchgear housings.
INDOOR INSTALLATION
1. Prior to uncrating, the switchgear should be
moved near installation site. This operation may be
completed by raising switchgear shipping skid with
track jacks to allow rollers to be placed under skid.
