LS BUS DUCT Series have ;
1.1 High Quality & Stability of a Power
Distribution System
4 LS CABLE
When electrical power energy becomes more widely used in industry, this kind of needs creates profitable energy
carrying and distribution system to supply the machinery with electricity.
Basically, LS BUS DUCT has been designed, manufactured, and provided in the following conditions.
INTRODUCTION
Suitable to Mass-Current
LS BUS DUCT, which can carry massive power up to
7500A with lower losses is used as distribution system
for main line according to needs of high-rise building and
factory plant through the features of flexibility, safety,
reliability, economical efficiency.
LS BUS DUCT system is simplified so that load may be
freely diverged, extending, moving, replacing and
maintenance of the load easily.
Meanwhile, this has a fine view harmonized with modern
architectural sense.
Service Conditions
Ambient temperature : -15。C~55。C
Relative Humidity : 95% or below
Bus Bar
Copper bus bar has conductivity of 99% or more, or
aluminum bus bar has conductivity of 61% or more.
Connecting plates of bus bar conductors are;
- Tin-Plated : Copper Bus Duct, EPOXY(Cu, Al)
- Silver-Plated : Aluminum Bus Duct, F/R(Cu, Al)
This connecting plates improve the contact resistance
and prevent electrical corrosion.
Temperature Rising Stability
Temperature rising limits shall be within 55。C or less in
the external surface of duct, as specified IEC 60439-1, 2
Insulation Properties
Cless B(130。C) shall be applied on conductor such as
EPOXY, PET and MICA(1200。C) for F/R.
FRP(Fiber Reinforced Plastic) shall be applied as a
spacer between conductors of joint part or conductor
and duct. All of these insulation materials have a very
high electrical dielectric strength of AC and impulse
properties.
LS BUS DUCT can be generally covered the rated
insulation voltage up to 1000V.
Lower Voltage Drop & High Short-
Circuit Ratings
Because of its extremely low impedance, voltage drop
is low also. This efficient design allows power to be
delivered with the highest efficiency possible.
Also LS BUS DUCT has a very high short-circuit
withstand strength.
This makes LS BUS DUCT guarantee for safe
application in commercial or industrial facilities.

5. 1.2 Easy Maintenance & Intelligent Bus Way System through an
Evolutional Process
TECHNICAL DATA INSTALLATION PROCEDURETEMPERATUREMONITORINGSYSTEMforBUSDUCT
LS BUS DUCT has very compact design by using effective heat radiation structure and Aluminum housing for
outside protection. So the weight is extremely light and it makes easy installation and maintenance.
Especially LS BUS DUCT has a special intelligent function of self-temperature monitoring system optionally
which is using optical fiber as a temperature sensor. This optical fiber is embedded in/on bus duct structure and
can easily measure distributed temperature of bus duct line at real time.
Compact Size
Easy heat radiation design of protection housing
brings small size of bus bar conductor. Aluminum
housing makes the bus duct system to be lighter than
other conventional bus duct. LS BUS DUCT requires
less space than wire and conduit.
Easy Installation and Savings
LS BUS DUCT has extruded aluminum housing and
incorporates with “joint kit type”. So light weight, simple
joint connection work can improve the installation
process faster. As a result, it makes cost down of bus
duct installation works.
Temperature Monitoring of Bus Duct
distribution Line (optional)
Integrated monitoring system of bus duct distribution line
at real time. (temperature, fire, vibration etc...)
Easy and early countermeasure is possible for
unexpected accidents.

LS BUS DUCT is covered all of the distributed capacities of buildings and factories from 600A up to 7500A
power distribution line. Especially LS BUS DUCT is very compact and has a light weight, so it can be simply
installed with using special joint kit which has two connecting plates and drastically decreased the contact
resistance.
LS BUS DUCT‚ basically has an IP54 degree and can be easily enforced to be IP65 degree. It has a temperature
monitoring function if needed.

9. 2.2 Grounding and Harmonics
9LS CABLE
LS BUS DUCT can provide a very large grounding capacity according to flange end terminal. As housing itself,
the cross section of our aluminum housing has over 100% of internal bus bar conductor’s area in 2,500A.
Therefore the housing itself can play a good role of grounding conductor with low impedance as well as heat
radiation at the same time.
In the cases of more increasing grounding capacity, internal grounding bus bar is built in the system, providing an
integral 50% &100% current capacity for ground path.
Some special operating cases under the non-linear loads, LS BUS DUCT offers added neutral bus bar which has a
100~200% increased bus bar size because of harmonic currents. The more modern industrial and commercial non-
linear application loads increase, the more harmonic current increases in bus duct system. In this case the ampacity
of the neutral bus bar should be increased. Especially even if the 3-phase currents were balanced, this harmonics
cannot be disappeared and lead to deterioration of distribution system and equipments. This neutral bus bar is
available to minimize the harmonic effect and provide safe operating condition within the heat limit rates.

12. 2.5 Temperature Monitoring (Optional)
INTRODUCTION GENERAL SPECIFICATIONS PHYSICAL DATA12 LS CABLE
One of the most special and remarkable characteristics of LS BUS DUCT is accompanied with the temperature
monitoring performance under the live-line condition of busduct system.
If this temperature monitoring system is installed at buildings and factories, unintended accidents will be
forecasted and prevented earlier time.
Temperature Monitoring System of the bus duct line uses optical fiber as a temperature monitoring sensor. This sensor
can be embedded in/on Ez-WayTM
bus duct housing.
Using only one fiber, the system can measure distributed temperature of several kilometers.
ABF (Air Blown Fiber) enables easy integration & installation where access is difficult, especially this method is
powerful in the already installed bus duct line.

These are identical values per meter for line to neutral at 60 Hz. In case of 50 Hz, multiply reactance (X) by 0.83
and resistance (R) do not change due to very small frequency effect.
Calculate voltage drop of line to line as following equation. cosθis power factor.

4.3 Temperature rising Test
The temperature rising limit values of LS BUS DUCT shall not be exceeded for specified value as the connection
section of conductor by 70˚C or less and outside duct by 55˚C or less.
Effective heat radiation structure and material properties of LS BUS DUCT prevents the over heating of bus bar,
joint box and its outside duct system within the temperature limit values of IEC 60439 1&2 under the rated
currents.

5.2 Principles
Bus Duct Temperature Monitoring System uses optical fiber as a temperature sensor and can measure
distributed temperature of several thousands of meter with ±0.5°C accuracy.
ABF (Air Blown Fiber) enables easy integration & installation where access is difficult such like a bus way line.
Easy operation & user-friendly GUI (Graphic User Interface)
Temperature Measurement
When the light pulse is launched into the fiber several backscattering lights returns to input end. Temperature based
on the intensity of Raman back-scattered light is used to determine the temperature of the optical fiber sensor. ⇒
Accuracy : ±0.5°C
Distance Measurement
The position of temperature reading is determined by measuring the arrival time of the backscattered light pulse similar
to OTDR (Optical Time Domain Reflectometer)
⇒ Measuring resolution : 1 m

ABF (Air Blown Fiber) Technology
After installing flexible tube, optical fiber is flown into the tube by air blowing pressure.
Applying various tube connector, it is easy to install fiber in narrow space & curved line.
Shortening the laying duration & minimizing the optical joints & easy to replace.
