In modern electrical installations, especially in sensitive environments with high plant density, the management of magnetic fields is no longer a detail. It is a design requirement.
With the K Series, a casing shield can be integrated that can reduce the magnetic field to less than 1 μT at 1 meter.
What does this mean exactly?
• Greater compatibility with sensitive environments (hospitals, data centres, offices)
• More freedom in plant design and layout
• Less interference with electronic equipment and systems
An advantage that is also becoming increasingly relevant in the tender phase, where the requirements related to EMC and magnetic fields are increasingly required.
Shielding is a solution to be evaluated based on the actual context, current, configuration and installation, because performance always depends on the system.

Choosing the most suitable busbar system for an electrical system is a crucial step in ensuring safety, operational continuity, and consistent performance over time. Each type of busbar has different construction and behavioural characteristics, which make it more or less suitable for specific application contexts.
Among the solutions offered by Graziadio, ISOLSBARRA and the K Series represent two systems with different technologies: one individually insulated in fiberglass or PVC, the other designed with a sandwich architecture to maximize compactness and heat dissipation.
This guide provides a clear and structured comparison of the two systems, helping designers and installers choose the solution best suited to their needs.
Overview of the two systems
ISOLSBARRA
ISOLSBARRA is a system of individually insulated fiberglass or PVC busbar trunking systems, designed to ensure high dielectric strength and maximum protection from external agents such as dust, humidity, and contaminants. The fiberglass or PVC seamlessly insulates the busbars, ensuring constant protection along their entire length, guaranteeing an IP66 or IP68 degree of protection.
Consolidated features:
Individually isolated phases.
High protection against infiltrations and deposits.
Superior mechanical and environmental resistance.
Reduction of risks arising from humidity and dust.
Ideal for applications with critical or particularly severe environmental conditions.
K Series
The K Series is a sandwich-architecture busbar trunking system designed to offer high compactness, excellent heat dissipation, and great installation versatility. The modular structure allows for rapid installation and efficient space management.
Consolidated features:
Sandwich structure that optimizes thermal dissipation.
Extremely compact layout.
Quick and easy installation thanks to its modularity.
Easy maintenance.
Versatile solution for industrial and infrastructure applications in standard environmental conditions.

Standard or infrastructure environments → K Series
2. Level of protection required
Maximum protection and operational continuity → ISOLSBARRA
Balance between protection, compactness and efficiency → K Series
3. Project priorities
Compactness → K Series
Total barrier and complete insulation → ISOLSBARRA
Regardless of the system chosen, both busbar trunkings are designed with the same principles that have always characterised Graziadio:
Attention to safety,
Certified construction quality,
Long operating life,

Design and production Made in Italy.
Graziadio supports designers and installers throughout every phase: system definition, component selection, configuration, and dedicated technical support.
ISOLSBARRA and the K Series represent two different solutions for different design needs. The former guarantees maximum protection and reliability in harsh environments; the latter offers compactness, versatility, and optimal thermal management. Correctly analysing the application conditions is the first step in choosing the most suitable busbar trunking system and ensuring the system’s high performance over time.
For a complete evaluation of the most suitable solution, it is always advisable to contact the Graziadio technical office for a dedicated analysis.
ELECTROMAGNETIC fields: with busbars, they are not a problem!
♀️ Did you know that electromagnetic fields can have negative effects on health and electronic equipment?
In particular facilities, such as hospitals or data centers, it is essential to minimize these emissions.
This is why busbars are a valid solution: compared to traditional cables, precisely by virtue of their structure, they have a very low electromagnetic emission.
In the carousel, we explore this aspect!
We also remind you that:
◾ Our technical department is available to calculate the electromagnetic emission of a given system, also through simulations.
◾ our K Series busbar duct is available in the Emagnetic version, with a very low magnetic field, and can be installed near particularly sensitive environments.
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.
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.
