Southwestern Battery Supplys Bus Duct System is unique in that it is housed in anenclosure constructed entirely of high strength clear polycarbonate plastic. The system

is built on site without the need for special rigging, cranes or lifts. The Bus Duct System

can be installed supported by stanchion support poles upon the floor , or suspended

from the ceiling utilizing standardized support structure framing.

The Bus Duct enclosure has removable side covers to allow easy access to perform

maintenance, as well as providing access to the bus to add additional battery drops.

The design of the Bus Duct provides for flexibility in the location of the battery drops

in that they may be located anywhere within the available room on the bus.

Polycarbonate covers are provided to insulate the battery drops, as well as where the

cables or flex bus will attach to the drop.

Each polarity is housed in separate sections of the enclosure so that when a side cover is

removed for access, the other polarity is still enclosed for safety, limiting the shorting

hazard. The Bus Duct is provided with ventilation holes to eliminate any heat build up

inside the duct.

Virtually any Bus Duct layout is permissible with our design. This includes both

vertical height changes from the battery room to the equipment room, as well as busarrangements, which penetrate though a building floor, connecting one floor to

another.

Our Bus Duct has been thoroughly tested. Computational Fluid Dynamic analysis has

verified that our design excels at its ability to keep the voltage drop at or below that

which was specified by the customer, while maintaining its rated ampacity.

Southwestern Batterys Bus Duct has undergone analysis by

Underwriters Laboratory Conformity Assessment and complies with:

UL Subject 1801

Telecommunications D.C. Power Equipment Dated July 1997
