Busbar trunking: the ideal solution for industrial plants

In a constantly evolving sector such as the industrial one, energy efficiency and plant safety are absolute priorities. Electricity distribution plays a crucial role in ensuring operability and reliability, especially in high-intensity contexts such as production plants, data centres and large infrastructures. In this scenario, busbar trunking emerges as the most advanced technological solution to optimize energy transport, reducing waste, simplifying installation and ensuring exceptional durability over time.
But what makes busbar trunking so high-performing compared to traditional systems? In this article we will explore every detail, highlighting the advantages, structure and main fields of application.

What is busbar trunking?

Busbar trunking is a modular system designed to distribute electrical energy safely and efficiently.
Unlike traditional electrical wiring, it uses conductive bars enclosed in an insulating and protective casing.
This system allows for the transport of large amounts of current with reduced dimensions and maximum safety, making it ideal for industrial applications, strategic infrastructures, large commercial and civil buildings.

What does busbar trunking look like?

Busbar trunking consists of:

  • Conductive bars made of copper or aluminium, which transport energy.
  • Insulating sheath (in PVC or advanced thermoplastic materials) that guarantees electrical and mechanical protection.
  • External metal or plasticized structure for protection from impacts, atmospheric agents, water and dust.
  • Quick couplings and modular systems for simple and safe connections.

Depending on the needs, busbar trunking can have different characteristics:

  • Resistance to extreme conditions (high temperatures, humid environments)
  • High protection levels ( IP66, IP68 )
  • Easy expansion and modification without invasive intervention

Why choose busbar trunking instead of traditional cables?

In recent years, busbar trunking has become the preferred choice for industrial plants due to its numerous advantages:

  • Superior safety: thanks to insulation, protection from dust and water (with protection levels up to IP68 ).
  • Quick installation : pre-assembled modules allow for shorter installation times compared to traditional cables.
  • Simplified maintenance : the components are easily inspected and replaced.
  • Modularity : the system can be expanded, modified or adapted without invasive demolition.
  • Energy efficiency: energy loss is reduced, increasing overall efficiency.

Although cables are still used in many plants, in advanced industrial contexts the busbar trunking is establishing itself as the standard for a series of concrete reasons:

Comparison table

Characteristic Bus duct Traditional cables
Safety Very high (IP66–IP68) Media (requires channelling)
Installation time Fast, modular Slower and more complex
Future expandability Very easy (adding modules) Complex (new wiring)
Energy efficiency High (less dispersion) Lower (cable losses)
Inspection and maintenance Simple and fast Difficult
Average implant lifespan >30 years 10–15 years

 

Conclusion : Busbar trunking is safer, quicker to install, longer-lasting and more flexible than traditional wiring.

Where is busbar trunking used?

Thanks to their versatility and reliability, busbar trunking is used in:

  • Industrial plants  where continuous power without interruptions is required.
  • Airports  to support critical infrastructure such as lighting and security systems.
  • Tunnels and subways  harsh environments where protection against humidity is essential.
  • Hospitals and large healthcare facilities  safe power supply for life-saving equipment.
  • Data centre ➔ continuous and easily changeable power supply.
  • Strategic infrastructures ➔ such as the Pedemontana Veneta highway , where Graziadio has made an important supply.

Why is copper called “”RED GOLD”?

Why is copper called “red gold”?

No doubt because of its distinctive colour, but that’s only part of the story. In our sector, especially in busbars, it is a real treasure for its properties, guaranteeing high performance and a long life to the systems.

In our products, copper is an alternative to aluminium conductors, and like the latter, it is truly a “super metal”!

Let’s talk about ALUMINIUM

Aluminium is a SUPERMETAL:

In addition to possessing exceptional physical and chemical properties, which make it super resistant and versatile, it is also environmentally friendly, very easy to recycle and with low costs.

We have always used aluminium in the production of our busbars, using it for both the outer casing and the inner conductors, helping to create an eco-friendly product with an extremely low environmental impact.

Save energy with busbars!

How much energy is wasted unnecessarily in electrical systems?

⚡Sunday 16 February was the International Day of Energy Saving, created to reflect on all those actions, large or small, that can help reduce energy waste.

If we talk about technologies capable of optimizing and reducing energy consumption, the busbar system also offers a small contribution in this regard.
In fact, busbars are confirmed as an energy-efficient solution, as they use energy better and make systems more sustainable, minimizing electricity waste compared to traditional cables.

Making better use of the electricity we consume is important. How does this process take place?

Save energy

The earth trembles:

You know, these events do not warn, and in an instant everything could stop… lights off, machinery blocked, safety of people compromised.

The vibrations of an earthquake put every component of an electrical system to the test. To avoid damage, even very serious damage, busbars must go through rigorous tests that prove their resistance to stress, even the most violent.
