Fundamental to providing safety to people and property, electrical continuity also plays an essential role in the EMC performance of an electrical installation.
The electrical continuity of a system is its ability to conduct electric current. Each system is characterised by its resistance R.
If R=0 Ω, the system is a perfect conductor.
If R is infinite, the system is a perfect insulator.
The lower the system's resistance, the better is electrical continuity will be.
Even at the same electrical potential each part of the cable tray helps dissipate any fault currents :

CABLOFIL Trays Tests show that CABLOFIL more than meets the requirements of the standard IEC 61537, which stipulates that cable tray resistance must not exceed 5mΩ/m. CABLOFIL Couplers The standard IEC 61537 states that coupler resistance must not exceed 50mΩ. The test involves running an electric current trough the system (cable trays + couplers) and measuring coupler resistance. |

An average of 0.82 mΩ for CABLOFIL couplers. This is between 50 and 80 times better than the requirements given in the standard.
All CABLOFIL couplers are tested and compliant. Please contact our technical support service for the full results of these tests.
