Busbar vs Cable
main problems with cable system:
•poor flexibility
•long time in installing and checking
•voltage drop
•bad heat dissipation
•need cable tray or pipeline
•short life of pvc and insulation material
the solution
busbar system

8 good reasons to choose BUSBAR:
1 – Busbars have compact structure. Compact structure is provided by placing
insulated/separated conductors in the housing. Busbar systems need less
space than cable systems, especially for high ampere rates.
2 – Busbars have sheet metal body. This helps transferring the generated heat
out through metal housing. Cooling is better than cable systems.
3 – Busbars can be applied to any kind of building by its modular structure. The
design of busbar system can be changed in the future and/or moved to another
building then installed again.
4 – Busbar systems do not burn, do not carry flames and do not generate
poisonous (halogen, etc.) gas incase of fire. Cable systems can burn and enable
fire to split out in the buildings (especially required in high-rise buildings and
shopping centers).

5 – Installation time is much shorter than cable systems. This provides low
installation and man-power costs and helps for better time management.
6 – With robust structure, short circuit stand is much higher than cable systems.
7 – Especially for high ampere rates, compact structure reduces the distance of
conductor’s axis and this reduces inductive reactance. Result of low resistance
and impedance, voltage drop is much lower than cable.
8 – The compact structure and steel sheet housing allows much lower
electromagnetic field around busbar system than cables. High current rated
busbars (4.000A-5.000A busbars) can be safely installed by the data cables.
Busbars do not create electromagnetic interference on data system.
