The Package Compact Substations are completely self-contained, mounted on an integral base, factory
assembled in a totally enclosed, aesthetically and acceptable cladding, vandal-proof, vermin-proof and
weather-proof housing ready for installation into position on a concrete base pad or pier.
The base frame is of welded structural steel and been hot-dipped galvanized after fabrication to assure
affective corrosion resistance in service.
Housing of the Package Compact Substation is made of special material called ALUZINK, a sheet steel
with a metallic alloy coating. The alloy consists of 55% aluminum and 43.4% zinc. This provides
optimum corrosion protection.
The housing has three compartments, separated with ALUZINK sheet. The transformer compartment is
completely separated from the medium voltage and low voltage compartments.
RECEIVING / INSPECTION / STORAGE
The Package Compact Substation is shipped from the factory ready for installation on site. It has been
submitted to all normal routine tests before being shipped, and it is not required to do any voltage testing
before putting it into service, provided the substation has not sustained any damage during transportation.
Immediately upon receipt of the Package Compact Substation, examine them to determine if any damage
or loss was sustained during transit. If abuse or rough handling is evident, file a damage claim with carrier
and promptly notify the nearest ABB office. ABB ELECTRICAL INDUSTRIES CO. LTD. is not
responsible for damage of goods after delivery to the carrier; however, we will lend assistance if notified
of claims.
PERSONNEL SAFETY
The first and most important requirements are the protection against contact with live parts during normal
service as well as maintenance or modifications.
This is the reason why all live parts have been metal enclosed, so that when the parts are live and the
Package Compact Substation doors are open, no one can be able to touch them.
Also, it is safe in case any short-circuiting or sparking occurs at the busbars.
VENTILATION
Transformer compartment has been provided with sand trap louvers, to prevent ingress of sand and that
proper air circulation should take place.
EARTHING
Proper earthing busbar has been provided.
HANDLING
Lifting lugs has been provided on top of four corners of the housing for lifting the DPS by crane and
chains as a single unit, otherwise this can be done by a forklift of sufficient capacity, but the lifting fork
must be positioned under the transformer portion.
