2.0 Receipt & Storage prior to installation
2.1 General
The breaker with complete packing should always
be stored indoor to protect from direct sunlight
& rain/snow.
Breakers can be stored upto 3 months from date
of shipment from the factory. For longer storage,
the packing needs to be removed and the breaker
be kept under controlled environmental conditions.
We define storage in controlled conditions as a
place with :
Leak proof roof
Solid, flat ground
Relative humidity less than 50%
Temperature 20°C (± 10° C)
2.2 Receipt & Storage of Breaker
Each delivery, on receipt, should be checked
for:
Shortages and discrepancies. (Check
against order and delivery documents).
Any transit damage and material losses.
Abnormality, if any, must be notified
immediately to: ABB, forwarding agents
and the insurance company.
The operating cabinet should be unpacked on arrival.
If it is not going to be stored in an approved storage
the heating elements must be connected
permanently to the electric supply to protect the
control equipment from corrosion or freezing damage.
The breaker with duct & poles should be stored in their
original transport units, where they are well protected
from damage. The breakers if stored outdoors, should
be well covered with tarpaulin. The tarpaulin should
not be placed directly on breaker. An air gap should
be left to prevent condensation.
The minimum allowed ambient temperature for the
Outdoor Vacuum Circuit Breaker is (-)30°C.
Structures may be stored outdoors.Spare parts should
be stored indoors in a recommended storage area
in their original packings.
