Trunk busbar system is made of copper or aluminium as conductor, metal slot as the cover to carry and distribute the high current power in industry, building, and power industry field. Trunk busbar system is a power distribution solution of size saving, flexible installation and flexible maintenance, repeatedly installation and uninstallation. 

       Trunk busbar system used in data center to carry the power to head cabinet and its related rack machine. As below listed are key difference between the traditional head cabinet + cable and new trunk busbar system.      

       Traditional head cabinet + cable:

1. Cable installation takes much more time, not economic for change or upgrade in future

2. Heat gathering with higher fire risk

3. Underground cable installation brings down the effect of air cooling

4. Longer cable with higher resistance brings more power loss

5. Head cabinet occupation reduces the utility size of data center room, 10% at least.

       Trunk busbar system:

1. Quick and flexible installation, much less time, economic for further change or upgrade in future based on the modular design power head and socket box

2. Metal of copper as conductor has higher power efficiency and less risk

3. Installation in air, better effect for air cooling

4. No cross impact due to the switch located in different socket boxes.

5. Save room size by removal of head cabinet.
