1. Transport and handling
Chapter 2 Transport, handling,
inspection and storage
1.1. The switchgear must be transported under the conditions that
the load switch is in “OFF” position, with its charging device
in “energy-releasing” state and the ground switch in “closed”
state.
1.2. The outer packing of the switchgear shall have anti-shock,
moisture-proof and dust-proof performance, and be adaptable
to railway and highway transportation.
1.3. In the case of handling by hand-push type forklift or by freight
forklift, the switchgear should be put onto the transportation
pallet (see Figure 10.1). In the case of crane handling, the
lifting hook of the crane should be hooked into the two lugs
on the top of the switchgear. The angle between the lifting
rope and the top of the cabinet shall exceed 45° (the angle
between the lifting rope and the plumb line shall not exceed
45 °), so as to avoid any deformation to the cabinet or the lug
(see Figure 10.2).
2. Inspection and storage
2.1. Visual inspection
Users shall make open-box inspections in a timely manner
after receiving the goods, to check the equipment for any
damages or deformation during transportation.
2.2. SF6 gas pressure inspection
When the product is delivered from the factory, SF6 gas has
been filled, with the gas relative pressure of 0.03 MPa. During
on-site inspection, the gas density meter will indicate whether
the pressure of the gas is normal (normal when the pointer
points to the green area, and abnormal when pointing to the
red areas).
2.3. Accessory inspection
After unpacking the package, please check whether the
equipment’s primary scheme conforms to the requirements
of the order, and whether the accessories are complete, such
as the equipment’s factory data, special opening tools, and
spare parts. In the case of any errors, please contact the
After-sales Service of Cooper Electric in a timely manner.
2.4. Storage
If the equipment can not be installed in time and has to be
stored for a period of time, use the original packaging
materials to properly pack the equipment after open-case
inspections, and store the equipment in a dry and clean place,
to avoid any mechanical damages to the equipment.
1.4. During loading and unloading, the switchgear shall be handled
according to the storage and transport indication mark on the
package, to avoid equipment damages. In general, the
switchgear should be moved vertically, to prevent from tilting
or turning over.
1.5. In the case of any damages found on the switchgear after
long-distance transportation, notify the cargo division
immediately to have the damage accidents identified.
CAUTION
IN THE CASE OF ABNORMAL GAS PRESSURE, NOTIFY THE AFTER-SALES
SERVICE OF COOPER ELECTRIC IN A TIMELY MANNER FOR DULY AND
PROPER HANDLING.
CAUTION
CHECK THE WEIGHT OF THE SWITCHGEAR. DO NOT USE WORN OUT
AND DAMAGED STEEL ROPES OR LIFTING RINGS. DO NOT USE THE
LIFTING EQUIPMENT WITH THE LIFTING CAPACITY LESS THAN THE
WEIGHT SHOWN ON THE NAMEPLATE OF THE SWITCHGEAR.
