FURUKAWA H-P BUS DUCT SYSTEM
Structure and Feature
Feeder Bus Duct
●Excellent insulated conductor
●No temperature gradient
The uniform insulation layer of heat resistant vinyl has a very
excellent electrical and mechanical feature coupled with a
no edge conductor. The quality is stable, since the insulation
coating method is continuous extrusion.
As convection is not caused inside the duct, so temperature
gradients is not induced by installation conditions such as a
vertical installation, a flatwise installation and an edgewise
installation.
●Compact and light weight
●Safe against fire
Since the conductor and the duct are contact, then the
external dimensions are small, and the laying space can be
The insulation coating is self-extinguishing and there is no
space in the duct, then there is no risk of the flue of a fire.
saved. So its weight is reduced by the improved efficiency of
each portion.
●No noise
●Low voltage drop
The duct and conductors are integrated, and vibration sound
is not caused by a current flow.
The small conductor mutual distance results small reactance
and very low voltage drop.
●Less magnetic flux leakage
●High short circuit capacity
The structure is very strong against the electromagnetic force
generated between the conductors, and a high short circuit
capacity can be ensured.
Since phases are close each other, then external leakage
magnetic flux is small, and influences to telecommunication
lines are low.
●Easy installation and maintenance
The features of compact, light and one-touch jointing make
installation very easy.
Since the entire surface is coated with insulator, then risk
of electric shock is less and concern about insulation
deterioration caused by dust and moisture is low.

●High clamping reliability
A snap pin hole, for clamping confirmation, is perforated
at threaded part of a joint bolt, and highly reliable clamping
can be obtained by just fastening a nut with a common
wrench until the hole is exposed. No special torque control
is required, in addition multiple times of tightening and
loosening are available.
●Perfect joint system
If clamping is insufficient, the snap pin hole, for clamping
confirmation, does not expose as the hole is hidden in the
nut. Then the snap pin, for clamping confirmation, cannot
be inserted. In other words, by checking the insertion of
the snap pin, for clamping confirmation, clamping can be
confirmed whether completed or not. Furthermore, a red
display plate is attached to the snap pin, for clamping
confirmation, to be able to be confirm from a long distance.
In addition, the snap pin, for clamping confirmation,
has a nut anti-loosening effect. Then additive tightening
maintenance after the installation is not required.
●Highly reliable leaf spring
The thick and large size leaf spring, employed even for
vehicles, is used. Because of the sufficiently large amount
of deflection in tightening, uniform conductor contact
pressure is induced then high reliability is obtained.

●No bolt through hole in the conductor
Tightening bolts are placed at parts where the conductor
is completely avoided. Then the conductor has no bolt
through hole and has high electrical and mechanical
reliability.
●Spacer has high strength
Since the spacer is made of high performance materials
and has no bolt through hole, then no stress concentration
is caused. So, the spacer has high mechanical and
electrical safety.
●Earth wire is not required
Earth wire is not required because structural duct each
other can be electrically connected automatically by
attaching the joint cover.
●General features of batch tightening joint
○J
ointing work is simple and construction time is
shortened.
○T
ightening maintenance is available during energization
and maintenance can be easily carried out.
○ The structure is compact.

Actual Measurement Method
Straight Portion
Prior to measurement, it should be
confirmed that there is no misalignment in
the bus duct laying.
The distance between the V-grooves of the
joint case (A) is measured.
(A)
V-groove
Edgewise Elbow
The center line of the bus duct is extended
with a straight tool such as a ruler.
The distance between the extended bus duct
center line and the V-groove is measured.
The distance at the other side is measured
in the same manner.
Flatwise Elbow
The cor ner point of the bus duct is
extended with a straight tool such as a
ruler.
The distance between the extended bus duct corner point
and the V-groove is measured and the measured value is
deducted by the 1/2 of the bus duct height dimension.
Edgewise Offset
The V-groove line is extended with a
carpenter’s square, etc.
The distance between the extended
V-groove line and the V-groove on the other
bus duct is measured.
The side plane of the bus duct is extended
with a straight tool such as a ruler and the
distance to the side plane of the other bus
duct is measured.
23
Flatwise Offset
The side plane of the bus duct is extended
with a straight tool such as a ruler and the
distance to the side plane of the other bus
duct is measured.
The V-groove line is extended with a
carpenter’s square, etc. and the distance
to the V-groove on the other bus duct is
measured.
Edgewise Tee
The center lines of the bus ducts are extended with 2 straight tools such as rulers, and the distances from the crossing point to each V-groove
are measured.
Flatwise Tee
The corner points of the bus duct are extended with 2 straight tools such as rulers and the distances from the crossing point to each V-groove
are measured and the 1/2 of the bus duct height dimension is deducted from the measured values.
Combination Elbow
The bus duct center line and the plane
of the side face of the other bus duct are
extended with 2 straight tools such as
rulers, and the distance is measured, then
the 1/2 of the bus duct height dimension
is deducted from the measured value.
The V-groove position is extended with a
plumb (or a carpenter’s square). The plane
of the side face of the other bus duct is
extended with a straight tool such as a
ruler. The distance is measured and the
1/2 of the bus duct height dimension is
deducted from the measured value.
The bus duct center line is extended
with a straight tool such as a ruler and
roll down the plumb. And distance to
the V-groove of the other bus duct is
measured.
＊The measurement methods shown above are just examples. On necessity a laser device or other devices are used in combination.

office or our agent office as soon as possible.
Reference
page
Avoid storing equipment and materials in hot, humid and areas with
the presence of corrosive gasses. Otherwise, dewing, rusting and other
causes will deteriorate the performance and likely to induce serious
accidents.
29
The installation shall be done following the specified method. There
is a possibility that the equipment cannot provide the expected
performance.
29
Be sure to observe jointing methods. Insufficient tightening of joint is
liable to cause heat buildup and damage the equipment.
30
Any joint components other than those attached must not be used.
It will be a cause of insufficient tightening, and a risk of burnout is
occurred due to overheating.
30
In the jointing work, be careful not to damage the spacer which is attached
to the conductor. There is a possibility to cause short-circuit failure.
31
There are two kinds of leaf springs; one is used to a bolt side and
the other is used to a nut side. Please perform attaching work after
confirming the condition at the time of delivery or the next figure.
Mistaking of the attaching direction leads a risk of insufficient tightening
which causes the burning due to overheating.
31
The pin shall be pulled out, after jointing the bus ducts in the upper floor
and the vertical spring hanger is attached.
33
The double nut portion must not be turned as the spring strength has
already been adjusted.
33
Make sure qualified personnel carries out maintenance and checking
work.
34
In order to maintain the functions and safety, make sure checking is
carried out as scheduled. When the system is used without making the
necessary checks and maintenance, failures are generated in equipment
and devices, and results in inducing serious accidents.
34
1-2. Preparation
(1)Thoroughly check the laying route bus duct to see if there
are any obstacles, heat source, water leakage, etc.
(2)Install the base channel for vertical hanger beforehand.
1-3. Laying
CAUTION
The installation shall be done following the specified method.
There is a possibility that the equipment cannot provide the
expected performance.
(1)U sing sufficiently strong materials and equipment for
transportation and lifting. The weight per 1m of H-P type
bus duct is given in the table at page 7. However, the
special bus duct with box sometimes weight 2-3 times
more than those shown in the table.
(2)When hanging the bus duct with a rope, insert thick pieces
of rag or corrugated cardboard between them to prevent
the bus duct from being damaged.
(3)A bus duct name plate is attached near the joint portion
of power source side; please set up by checking the duct
numbers shown in drawings.
29
(4)When moving the bus duct, the joint case portion shall
not be held. There is a risk to cause a problem such as
breakage of the insulation plate. The enclosure portion
shall be held to move the bus duct.
Joint procedure of the bus duct is as follow.

6. Test and inspection after the installation
7. Maintenance and checking
After the completion of the bus duct installation, a person
responsible for installation management (Qualified person)
shall measure the entire insulation resistance values and
shall confirm the completion of all the work by inspecting the
entire route by the method of (1) to (8) shown below; also the
person shall confirm the safety of the jointed equipments, and
activate the installed system. Here, we recommend that the
confirmation results of the important confirmation portions
shall be recorded following the cautionary notes ravels, and
store the record as the evidence.
When measuring the insulation resistance, the jointed
equipments shall be disconnected and, if the breaker is
attached, the breaker shall be turned off.
The insulation resistance value is difficult to be identified
because of the difference in the route length and the ambient
conditions; the value is usually 100 MΩ (500 V megger testing)
approximately in the dried ambient condition. If the value is
less than 10 MΩ, it is considered that there is some factors
which lowering the insulation. Each jointed portion shall be
checked following the joint procedure. (The confirmation can
be easily performed, if the intermediate check, shown in “1-3
Installation (7)”, has been carried out.)
(1)The bus duct is not damaged. There is no extreme twist or
meandering.
(2)The joint components are firmly attached. All the snap pins
for clamping confirmation are attached.
(3)T he equipment joint bolts are firmly tightened with the
specified torque. The blue surfaces of Belleville washers
face to the correct direction.
(4)The hangers support the bus duct firmly.
(5)The pins are pulled out as specified in the cautionary note
label of the vertical spring hanger. The double nut portion
must not be turned. (Check the marking.)
(6) Grounding is surely taken.
(7)A fter completion of the installation, the transport
reinforcement brackets are removed as specified in the
cautionary note label for the expansion.
(8)T he branches such as the plug-in box with mccb, the
tap box etc. are properly installed with the boxes which
have the specified capacity (confirmation of the insertion
condition and tightening torque of the bolts)

recommended for guaranteeing safe usage of bus duct for a
long time.
CAUTION
CAUTION
Make sure qualified personnel carries out maintenance and
checking work.
In order to maintain the functions and safety, make sure
checking is carried out as scheduled. When the system is used
without making the necessary checks and maintenance, failures
are generated in equipment and devices, and results in inducing
serious accidents.
(1) Appearance Check
Check the bus duct along its entire length to make sure
that there are no deformations, damage, smears or loose
joint with the join covers, hangers and plug-in breakers, or
crooks or other abnormal condition.
(2)Environmental Check
The environment in which the bus duct has been installed
may change immediately following its installation.
Therefore, the environment should be checked to see
that water, dampness, high temperature, corrosive gas,
excessive oscillation and dust have deteriorated the bus
duct.
(3) Joint Check
The H-P bus duct uses largely flexed leaf spring in its each
joint, so the joint has no potential to become loose due to
acclimatization and aging. This means that the joint needs
not be re-tightened at regular intervals. However, if during
installation or storage the joint surface has been damaged
or deteriorated, this will adversely affect it gradually. In
such a case, it is recommended that temperature of the
joint while being energized should be measured to check
its status. (If the temperature of the leaf spring is roughly
the same as that of the bus duct, there would be no
problem.)
(4)Loading Condition Check
For a Plug-in bus duct, requirement for an additional load is
anticipated after its installation. Therefore, a check should
be made upon installing an additional load. To make sure
that the sum of the load currents is not in excess of the
capacity of the bus duct. In particular, attention should be
drawn if the trunk line has been branched off by using a tee
or a cross.
(5) Insulation Resistance Check
Check the insulation resistance between the each
phase also between the earth and the phase. In the dry
atmosphere, the insulation resistant is usually 100 MΩ
approximately (500 V megger testing). It is recommended
to confirm and record the magnitude of the value also the
entire balance and the presence or absence of aging.
These maintenance operations are recommended to be carried
out about once a year as a guide.
