The right foundation for heavy electrical installations
Transformer rooms and MV/LV switchgear configurations are critical environments where transformers, high-voltage equipment, and hazardous installations converge. In these spaces, safety, clarity, and accessibility are of the utmost importance. Cables and conduits must be neatly organized, always accessible for maintenance and inspection, and fully compliant with the most stringent applicable safety standards. A cluttered or inaccessible floor is not only impractical in these environments, but can also create dangerous situations for staff and installers.
Intercell offers the ideal solution. The modular floor system conceals all cables and conduits neatly beneath the floor, ensuring a clear and safe working environment while providing instant access for maintenance and inspection at all times — without demolition work and without disruption. The system complies with the most stringent fire and safety standards and has been tested for electromagnetic compatibility, an absolute requirement in environments housing heavy electrical installations and transformers.
Why Intercell in transformer rooms and MV/LV substation configurations?
In transformer rooms and MV/LV substation configurations, there is no room for compromise. The consequences of a poorly organised or inaccessible space can be significant — from hazardous situations for personnel to costly failures in the electrical installation. Intercell is designed to minimise those risks. The system is fire-safety certified, tested for electromagnetic compatibility, and capable of withstanding the heaviest loads. These are the six key advantages for your transformer room or MV/LV substation configuration.
Fire-safe and certified
Intercell has been fire-resistance tested in accordance with EN13501-1 and EN13501-2, class Afl-s1. In transformer rooms where fire safety is critical, Intercell provides the required assurance and meets the most stringent standards.
Rapid access at all times
The floor panels can be removed in no time for inspection, maintenance, or repair of transformers and cables. No demolition work, no disruption, and minimal interference with the installation.
High load-bearing capacity
Class 4B in accordance with EN12825, with a maximum load of over 9 kN. Suitable for heavy transformers, switchgear cabinets, and other electrical installations without issue.
Electromagnetic compatibility
Intercell has been tested for EMC, with an attenuation of 25 dB between 3 and 30 MHz and 20 dB between 30 and 1000 MHz. Essential in environments with heavy electrical installations and transformers.
Structured cable management
All cables and conduits are neatly concealed beneath the floor. No loose cables, no trip hazards, and a well-organised space that complies with applicable safety standards.
Fast installation
Intercell is installed quickly on a levelled floor using adhesive bonding, with no drilling and no demolition work. Minimal disruption to your installation and your schedule.
Safety without compromise
In transformer rooms and MV/LV switchgear installations, safety is not a secondary concern. Heavy transformers, high-voltage equipment, and hazardous installations demand a floor that is reliable, meets the most stringent standards, and is always rapidly accessible for inspection and maintenance. A minor incident in a transformer room can have major consequences — for employee safety, for continuity of the power supply, and for the organisation’s costs.
Intercell provides that assurance. The system is fire-resistance certified, tested for electromagnetic compatibility, and capable of withstanding heavy loads. The floor panels can be removed and replaced with ease, enabling maintenance to be carried out quickly and safely — without demolition work and without unnecessary downtime. This allows you to focus entirely on what truly matters: a safe and reliable electrical installation that complies with all applicable laws and regulations.
Technical specifications
For transformer rooms and MV/LV switchgear installations, fire safety, electromagnetic compatibility, and high load-bearing capacity are the three most critical specifications. Intercell meets the most stringent standards in all these areas. Below is an overview of the most relevant technical specifications for your environment.
Fire classification
Tested in accordance with EN13501-1 and EN13501-2. Essential in environments with fire risk due to high-voltage equipment.
EMC attenuation
Between 3 and 30 MHz. Critical in environments with heavy electrical installations and transformers.
Maximum load
Class 4B in accordance with EN12825. Suitable for heavy transformers and switchgear cabinets.
Everything You Need to Know
About the Product
Is Intercell suitable for use in a transformer room or MV/LV switchgear installation?
Yes, Intercell is ideally suited for transformer rooms and MV/LV switchgear installations. The system neatly conceals all cables and conduits beneath the floor, is fire safety certified, and has been tested for electromagnetic compatibility — an absolute requirement in these types of environments.
Is Intercell sufficiently fire-safe for use in a transformer room?
Yes, Intercell has been fire resistance tested in accordance with EN13501-1 and EN13501-2, class Afl-s1. In transformer rooms where fire safety is critical due to the presence of high-voltage equipment and transformers, Intercell provides the required level of assurance.
Does Intercell hold an EMC certification?
Yes, Intercell has been tested for electromagnetic compatibility (EMC), with an attenuation of 25 dB between 3 and 30 MHz and 20 dB between 30 and 1000 MHz. This is essential in transformer rooms and MV/LV switchgear installations where heavy electrical equipment and transformers can cause electromagnetic interference.
Is Intercell capable of withstanding the heavy loads of transformers and switchgear cabinets?
Yes, Intercell is certified in accordance with EN12825, Class 4B, and can withstand a maximum point load in excess of 9 kN. The system is designed for use in facilities housing heavy electrical installations, transformers, and switchgear cabinets.
Can I access the cables and conduits for maintenance or inspection?
Yes, the floor panels can be removed easily and without tools. Cables and conduits are always quickly accessible for inspection, maintenance, or repair — without the need for demolition work or disruption. This is of great importance in transformer rooms and MV/LV switchgear installations, where regular inspection of the installation is mandatory.
Does Intercell affect the load-bearing capacity of the building?
Intercell is a lightweight system that adds only 22 kg/m² to the structure. This makes the system suitable for both new and existing buildings, even where the floor’s load-bearing capacity is limited.
Are additional cable trays required alongside Intercell?
No, Intercell eliminates the need for separate cable trays. All cables and conduits are neatly integrated within the system itself, reducing costs and keeping the space organised and accessible.
