PE (Earthing) Why is it important?


Our products offer A HIGH EARTHING SYSTEM: it is significant in terms of safety and reliability of operation of electrical systems.

➡ By providing a low resistance earth path, a high PE system can protect sensitive electronic equipment from potential damage caused by electrical faults or power surges. Vital in industries where equipment is critical to operations, in addition to the expense of the equipment

➡ All of our busbars have enhanced protection due to the external casing being produced with aluminium. This metal has a low resistance to electricity and consquently any fault current is discharged through it and then in to the ground

➡ In addition, the earthing system helps to stabilise voltage levels throughout the busbar system, providing a reference point (zero volts) for the system itself which is useful for maintaining the proper functionality of electrical devices.

DALI Lighting Busbar

DALI Lighting Busbar

DALI is the acronym for Digital Addressable Lighting Interface. It is a standardised protocol for lighting control in buildings.

DALI enables communication between lighting control devices such as sensors, switches and and luminaires providing flexibility and energy efficiency.

WIth Graziadio UK Ltd GLS Lighting Busbar, The DALI signal can be transported using two of the conductors normally used for electrical power. This is possible on a 4P busbar system as illustrated below, or on a 6P system if also requiring additional phases such as emergency lighting.

Tech Talk 2024 – London

tech talk

Talking about a great company, but in just 10 minutes?

There is so much to say about what we can offer…. but we’ll try!

We were proud to attend the Tech Talk event in London, which took place on 22 January 2024, where we were present with our partners from Italy.

These were meetings with some leading names from within the sector, learning about what is valued most by them so we can adapt our offering to suit. It was a delight to be able
to meet everyone face to face and show them first-hand our products, whilst also sharing ideas and projects, building connections and finding new opportunities!

Thanks to all who stopped by our stand to have a chat!

Blindocad Software



Blindocad is the modern software for  Graziadio & C. busbar planning from 25 to 6300 A, fully integrated  in Autocad, Ares, BricsCAD v10, ZWCAD, progeCAD, GStarCAD, BitCAD

The application gives the total technical execution of busducts in 2D and in 3D version, or the review of a previously created project. Through the layout of the electrical system, the application permits the complete elaboration of every single component and the following assembly with all the accessories. The result is a precise execution of the project by the addition of every single element: the straight elements, the elbows, the end feed units, the tap off boxes.

Data Center Nation Milan 2023

Data centers are the backbone of today’s digital economy, and new developments by cloud service providers are increasing the space of Italian data centres by more than 60 per cent.

Our busbars are now present in the world’s largest new Data Centers. We are projected to become more and more qualified and competent providers, so we will participate in the next Italian flagship event DCN Milan.

It will be an important opportunity to meet and network with the largest data centre operators and companies, and an unmissable opportunity to keep up to date with the latest trends in the sector.

We look forward to meeting you on 31 May at #AllianzMiCo!

Disneyland Paris

We provided busbars for the expansion of the “Disneyland Hotel“.
Disneyland Paris welcomes between 12 and 16 million visitors each year, who come from every country, and not just from Europe. The 2 theme parks that hosts 60 attractions and 7 hotels provide unforgettable experiences for children and adults of all ages.
The #busbars that were provided for the hotel makeover are K Series. This busbars have the capacity of 2500 A and are an excellent solution for electricity transportation. The chosen #busduct is sandwich type, compact in size, and has a high heat dissipation capacity.
With the K Series busduct, ideal for switchboard-transformer connections, the Disneyland Hotel will be able to have electricity and reopen in 2024.
Graziadio. Yes, We Busbar.

Coloured K-Series

A system in France, 4 line colors so as not to confuse the utilities and guarantee the electricity without errors even during scheduled maintenance.
Each element is uniquely identified in the drawing to simplify assembly, making work quick and efficient.

Eurovision – Turin 2022

The Eurovision was a great success for Turin, the show took place inside the Pala Alpitour where all the main electric backbones are made with GDA busbar ducts, reliable in all conditions of use.

Design to site

When it comes to power busbar trunking, a standard out of the box system is not always appropriate.

Graziadio UK can assist with providing bespoke systems, without the bespoke lead times.

Polo Davinci-1 Data Center Genova

We have supplied our busbar trunking for the project at Polo Davinci-1, Genova. It is a new Datacenter made by the Italian company Leonardo and it is among the top 100 in the world for power and performance.

Our supplied products are
* GDA 160A & GDA 250A thanks to which we offer a simple plug and play solution for power distribution. Power cables can be quickly installed with a large variety of tap off boxes, switches, plugs and meters.

* Isolsbarra 630A & 1600A busbars in aluminium and IP66

The flexible distribution of energy provided by Graziadio’s products is suitable for moving and changing load distribution frequently, very quickly and without cost.
