The Advantages of Using Aluminium Bus Bar in Electrical ...

One of the most critical components in electrical systems is the Aluminium bus bar. Bus bars are widely use to conduct electricity from one point to another and are vital for the efficient operation of electrical systems. While different materials are use to construct bar, aluminium has emerged as the material of choice for many facilities. This post will discuss the advantages of using These Bars in electrical systems.

Aluminium Bus Bars are are widely use in electrical systems to conduct and distribute electricity. The most commonly used material for bus bars is aluminium due to its excellent Conductivity, lightweight, and cost-effectiveness. Various elements are add to improve its mechanical and electrical properties in these bars applications. Some of the common ingredients used in Bus bar aluminium include: 

  • Copper
  • Magnesium
  • Zinc
  • Silicon
  • Manganese

High Conductivity of aluminium Bus bar: 

aluminium is the second most conductive metal after silver. It means that aluminium allows the flow of electricity efficiently. Bus bar aluminium provides low resistance to the electrical current, thereby limiting the loss of energy that occurs as heat. The high Conductivity of this Bar translates to a more reliable and efficient electrical system.

Cost-Effective Aluminium Bus Bar: 

aluminium is lightweight and inexpensive compared to copper or silver. The low cost of aluminium reduces the overall cost of electrical systems. For example, suppose a facility replaces copper with Bus bar ones. In that case, it will achieve cost savings, and the price of bus bar aluminium compared to copper would be much lower.

Corrosion Resistance Aluminium Bus Bar: 

bus bars aluminium are corrosion-resistant, meaning they do not deteriorate even in harsh environments. Aluminium forms a protective layer when exposed to the atmosphere, which prevents further oxidation or corrosion. This characteristic makes Bars highly suitable for use in corrosive environments.

High Thermal Conductivity Aluminium Bus Bar: 

These Bars conduct heat much better than copper or steel. The high thermal Conductivity of bus bar means they dissipate heat more efficiently. This is essential because the failure of an electrical system can occur due to overheating. Using these Bus bar reduces the risk of overheating, promotes efficient operation of electrical systems and reduces power consumption.

Easy Installation: 

These Bars are lightweight and easy to manoeuvre. They also come in longer and lesser thicknesses, making them ideal for tight spaces with complex configurations. Their light structure results in quick installation times, saving time and money.

Conclusion:

These Bars offer numerous advantages over other materials, which makes them a preferred choice in most electrical systems. The high Conductivity, cost-effectiveness, corrosion resistance, high thermal Conductivity, and easiness of Installation all contribute to a more efficient and reliable electrical system. bus bars should be at the top when looking for suitable materials for electrical systems.

Aluminium busbars is it a fashion statement



Not to seem alarmist (well at least until I came to know that roof panels can operate at 400Vdc - that was a wake up call and there have been roof panel fires from failures caused by internal shorts, kakapo's, baboons and aerial object impact damage, hence the insistence by the OZ Civil Servant to install manual breakers up on the roof near panels where you cant reach - nice), I think that a return to basic first principles
is needed and methods originally employed in dc high current systems. Yet I shall only deal with ELV systems 12,24,48Vdc in their ascending severity. For DIY IMHO the jury is out on whether 48V level is worth the risk - its 16x the destructive energy to contain.
At 12/24Vdc levels there is and abundance of well proven devices, tried and tested over decades from the auto industry, readily available provided they are suitably employed. KISS.

But some test rig proof is needed due to the very much greater ampacity and AIC (20kA) needs of Lion battery packs over traditional LABs.

I am aiming for a 500A sc rig first in my detached garage at least to get some experience on monitoring current interruptions at this level. I can record electrical graphs, temperature rises and physical effects, flash damage etc at say 32A level devices (tbc). I have to see what video equip I can muster.
Any help would be much appreciated and acknowledged

OBTW I hope to encompass knowledge from the US off-gridders/systems, ABYC boaties, OZ Rules and (baby in the party BS7671 Regs) so as to get a cross boundary consensus of good practice, after all the Sun goes round the World.

Well Guys I am building a test rig to throw some heavy current at these devices cos I simply dont believe all the hype and BS surrounding this new Solar fashion - but the physics and engineering behind the dc protective devices is not new. High ampacity dc systems have been around for a century in such industries as electroplating, traction (mines, trams, underground rail, telephony exchanges LAB storage UPS, industrial UPS systems, etc.) The technology is out there but covered in proprietorial mystique $$$$). The average DIY Joe only has catalog-claims to go on and little understanding of the nature of electrical protective devises - as evidenced by the squinching vids propounded by said amateurs OMG. Also said Joe (you gotta admire his enthusiasm) simply doesnt have the facilities to test the safety devices and may suffer when a catastrophic fault occurs (even the big kids get it wrong (cf Arizona Surprise incident).Not to seem alarmist (well at least until I came to know that roof panels can operate at 400Vdc - that was a wake up call and there have been roof panel fires from failures caused by internal shorts, kakapo's, baboons and aerial object impact damage, hence the insistence by the OZ Civil Servant to install manual breakers up on the roof near panels where you cant reach - nice), I think that a return to basic first principlesis needed and methods originally employed in dc high current systems.
