Smart Joint Paks, allow for
quick removal of lengths from
the busbar trunking runs for load
shifting or maintenance. It also
can be removed and relocated
on the opposite end of the
length for the last minutes job
changes.
Feeder Units, include flange end
and flange end box, which connect
to transformer or switchboard by
flexible links or solid links.
Straight Length Units, include
feeder and plug-in type. Ampere
start from 400A to 6300A can
m e e t m o s t o f t h e p o w e r
distribution needs. LB straight
length units are no Chimney
Effect.
E l b o w s , i n c l u d e f l a t w i s e ,
edgewise, Z shape, offset and
other types, adjust different
constructions.
Plug-in Units, feed the power
from the body of busway. The
protection unit inside PIU may
be circuit breaker or fuse.
H a n g e r s , f i x t h e b u s w a y,
include horizontal hanger and
spring hangers.

High purity conductor
Reliable insulation material
Aluminum-Magnesium Housing
Structures
Sandwich Structure
High IP
Sandwich Plug-in Opening
Self-piercing Riveting
Electrolytic coppers with purity over than
99.95% and conductivity over than 97.5%.
Silver plating along the length can reduce the
contact resistance and sawing section makes
the product more precision.
All bars are insulated by Mylar film from
Dupont, to prolong insulation service. The
insulation consist of two layers of heat-formed
polyester films surrounding each phase bar. It
means it can provide a solid insulation and the
excellent dielectric performance.
LB busway with fully enclosed by anti-
corrosion Al-Mg housing have been carefully
designed to reduce the weight, avoid the
hysteresis and eddy current losses.
LB busway is designed in sandwich-type
construction to provide superior heat transfer
effect and voltage drop characteristics. And
also LB busway is less space required for
installation and investment saving.
All the conduct and insulations are fully
enc losed wh ich can p rov ide a be t te r
protection degree. And totally enclosed
housing required no derating regardless of
mounting position.
Sandwich Plug-in Opening make a better heat
transfer effect in plug-in area, and also reduce
the impedance in plug-in opening.
High strength Self-piercing riveting can
reinforce the busway strength, which provide
superior protection under short circuit.

Smart Joint Pak
Plug-in Unit
Joya Electric provide the plug-in units with full
mechanical interlocks, which can prevent from
wrong operation and provide a good protection
to both people and equipments. All the plug-in
jaws are silver plated can reduce the contact
resistance and make a reliable connection.
Universal accessories
a. Connect the HV/LV
transformer and Switch
board.
b. Connect two LV
Switchboards.
c. Distribute power to
each load center in a
industry environment.
d. Distribute power to each
floor in a commercial or
residential buildings.
Smart joint pak connections can be removed
and replaced easily. Double-head bolt can
facilitate the installation and thermal indicator
on the joint pak can make the inspection and
maintenance much more easier.
The design of universal accessories can
make your installation much easier, however
in horizontal or vertical.

Step6 Protection Degree for different invironment.
In a dry distribution room or power well, IP42 is a good choice.
In a dry room with fire pipeline above, IP54 is a good choice.
Outdoor application and those case may be attacked by rain,
IP65+canopy will be preferable.
Note: before busway is compeletely installed, there is no protection
degree at all.

Step7 Choose the proper plug-in units.
Step8 Routing and accessories
Calculate the total power requirement based each load
requirement. For and real case, pls contact your local
consultant to get more detail or refer to the design manual
make a right power needs calculation.
Calculate the ampere rating according to the total power
requirement.
Verify the ampere according to voltage drop requirement.
When calculate the voltage drop, the distribution coefficient
must be taken into account, details refer to page 15 of this
catalogue.
Verify the short circuit withstand capability. Normally LB
busway can afford the worst case of short circuit between
phases. For any special requirement, please contact our
local sales representative for help.
According to load requirement, select circuit breaker of fuse as
protection unit. Calculate the ampere based on load capacity.
LB plug-in units provide ampere from 16A-630A. Normally the
branch rating should be less than half of busway trunking
ratings. When the branch rating is over than 630A, we suggest
to put Flange end box plus circut breaker of fuse breaker of
fuse to protect.
Improve the layout design, try to make one routing which is
shorter and less elbow. According to actual situation, design
necessary hanger supports, LB busway requires the hangers
interval does not over than 2m. When busway pass through
two buildings, expansion units is required. Others, please
contact our local sales representative for help.
