About Bus Bar Trunking system (BBT)

Busbar trunking systems (BBT) consist of insulated copper or aluminium busbars enclosed in a trunking. Use a specialist epoxy resin coating to insulate each conductor, the coating is applied to the busbars using an in-house developed and industry leading process. Modern busbar trunking is modular in design and is supplied in pre-fabricated lengths and available in a range of conductor configurations. The product range typically includes elbows, T-connectors, feeder units, panel flanges and various other standard or custom components that make it simple to configure for almost any application.

Product Features:

• Easy to design power distribution and clear network structure, easy engineering and installation possibility.
• Law ignition energy and high short-circuit value.
• Fast & simple installation with minimum tools.
• Tap-off connections can be made to Distribution Busbar lengths; Tap-offs can be added, removed and repositioned as necessary.
• During installation, there is no waste or scrap. So it’s environment friendly.
Easily be removed and re-used where required.

Advantages of Busbar System Over Cable System:

1 – Busbar systems need less space than cable systems, especially for high ampere rates.
2 –Cooling is better than cable systems.
3 –Modular structure.
4 – modern and esthetic look.
5 – 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).
6 – Busbar systems have no chimney effect, because of compact structure (KB type) or pre-installed inner fire barriers (KO type).
7 – Busbar trunking systems have the advantage of expansions, changes, replacements and reusing capability in the future.
8 – Installation time is much shorter than cable systems.
9 – During design stage of the building, busbar systems reduce the cost of other systems;
  a) Reduce amount of CABLE TRAYS,
  b) Reduce number of DISTRIBUTION BOARDS. It is possible to feed loads (machinery, floors, etc.) directly with tap-off boxes,
  d) Reduce number of the MCCBs / MCBs,
  e) Cancel many ACCESSORIES used for cable systems,
  f) Make easy to prepare projects and reduce PROJECT PREPERATION TIME.
10 – Short circuit stand is much higher than cable systems. (For example; for 3000A busbar, 264 kA peak and 120kA/rms)
11 –voltage drop is much lower than cable.
12 – Busbars do not generate electromagnetic interference on data system.
13 - Location of Tap-off boxes can be easily and safely changed according to future needs. Also, number of tap off boxes can be increased.
14 – Busbar systems are consisted of fully certified standard elements and designed to eliminate possible human mistakes. Such as tap off boxes/plugs are tested and certified parts of a busbar system and complies all safety requirements. Securities of all tap-off boxes are standard and does not change depend on the installer.
15 – Busbars cannot be bitten and damaged by various animals, which may live in the buildings (rats, etc.). Because, housing is steel sheet and it is not delicious.
