|In 1930's, United States started using Busduct
systems for high rise construction and some production
facilities. In 1950's, Europe and Japan began to use the system.
In 1980, Lectro started its first production from the latest
design of the most famous companies among the world. Lectro is
the pioneer in Busduct manufacturing in Africa and the Middle
Lectro's bus duct has been completely type tested at KEMA
testing facility in the Neatherlands.
What is Bus duct?
Busduct is an economical, modem method for distributing
electricity. It is a prefabricated insulated aluminum or copper
conductor enclosed in a metallic housing.
Using large cables for power distribution in high rise
buildings, industrial plants and commercial markets can
cause difficulties when running the cables into cable trays
or ducts or when there is a need for changes or extensions.
These problems are easily overcome using Bus duct systems
instead of cables.
The Busduct system has a lot of outstanding features
compared with conventional cable wiring.
Bus duct vs cable and trays
There are many advantages of bus duct over cables and
trays in distribution systems:
- Less man hours for installation
Bus ducts are built to fit customer specific layout
needs. It is delivered to the site ready for
installation. Bus ducts installation needs only about 40
% of the labor required to install cables and trays. All
parts of the installation can be easily mounted and
- Compact size
Due to its sandwich design, bus ducts have very compact
cross sectional sizes and they occupy far less space
compared with multiple cables.
- Reusable, expandable and flexible
As distribution may need changes, existing" bus duct
runs can be easily relocated or extended by adding new
sections. System components can be added, removed or
relocated after initial installation.
The power supply can be adapted to different production
processes simply by relocating the tap-off Units.
- Safe and versatile design
Lectro bus ducts meets the requirements of IEC 439-2.
The conductors are totally enclosed in a non ventilated
aluminum housing which provides one of the highest short
circuit ratings-in. the industry today. All bus plugs
are polarized to prevent improper installation.
- Lower installation cost
The saving in labor can generate a total installation
cost reduction of as much-as 40% compared Cables.
- Competitive at any rating
When reviewing material cost alone, bus duct may cost
more than cables and trays. However, it Is the reduction
in the number of man hours required for installation
that provides a significantly lower installation cost
Also the cable minimum curvature radius makes the bus
duct path less by 5-20% for runs with many elbows.
- Quick delivery
Lectro lead fames are more competitive than ever and
Lectro can handle the quickest delivery to meet the
- Easy ordering
Accurate layout can be done quickly with the help of
Lectro group. Just provide the equipment position,
dimension and general layout and Lectro will give
detailed aoorival drawings within one week receiving the
- Modern outlook
its functional advantages Busduct system creates a
modern view in buildings and factories where it is used.
