  • EMC Tests

    Carried out in independent and accredited laboratories, AEMC Measures and CETIM, these tests demonstrate the performance of Cablofil® in regard to the EMC of the electrical installation.

    1st test configuration AEMC Measures

    Data cable subjected to an external electromagnetic field

    A UTP category 5e cable, placed in an insulated chamber, is subjected to a severe electromagnetic field, simulating electromagnetic disturbance. Each different type of metal cable tray, connected to earth, is tested:

    Cable without metal cable tray; control

    Cable in Cablofil®

    Cable in Cablofil® + cover

    Cable in perforated tray

    Cable in trunking

    Results and interpretations

    The comparison of the results of each configuration of cable tray, wire mesh and perforated tray, with and without cover, shows the EMC performance of cable tray.

    These tests show that wire mesh and perforated tray offer the same "Faraday cage" effect.

    These results show that it is vital:

    • To use metal cable tray
    • To earth the cable tray
    • To use a cover if required

    Non metallic cable tray (PVC, composite material) has no effect against electromagnetic disturbances

    2nd test configuration

    Data cable alongside a power cable

    A UTP category 6 cable, placed in an insulated chamber, is subjected to an electromagnetic field created by a power cable. The following parameters are studied:

    • Impact of earthing
    • Separation distance : 0, 10, 20, 30 cm
    • Type of containment: wire mesh, perforated tray and trunking
    • Separated cable trays
    • One cable tray with divider and without divider

    118 configurations were tested

    An electromagnetic disturbance was created by passing a current in the power cable.

    The disturbance created in the data cable was measured.

    Disturbing power in the cable in dBpV


    Results and interpretations

    This 2nd test configuration confirms the attenuation effect of a metallic cable tray irrespective of its design (wire mesh or perforated tray).

    To obtain a good EMC, these results shows that it is vital:

    • To use metal cable tray
    • To earth the cable tray

    These tests show the importance of the following criteria:

    • To ensure maximum separation distances
    • To use two separate cable trays for power and data
    • To use a divider if sharing containment systems
    Never mix power cables and data cables in a solid bottom tray system

    Compression Testing

    During the test, 300 foot lengths of Category 5e and Category 6 test cable were placed in Cablofil cable tray, subject to zero load and tested to the requirements of TIA/EIA-568A Draft II (TSB-95) and TIA/EIA-568-B-2-1 Draft respectively.

    The test was performed in a Cablofil Tray and outside of the tray on the floor. Both tests were performed at no load and loaded down cable.

    Shock and Vibration Studies

    Nuclear Facility Vibration Study 

    Cablofil is often installed on machines that generate substantial vibrations. It seemed desirable for us to fix the limits of our product regarding this utilization, especially since in the nuclear field, our cable path is required to withstand 2 or 3 g of acceleration for 30 to 45 seconds at a frequency of 15 Hz.

    MIL-SPEC 901 Vibration Study

    Cablofil Tray is the only wire mesh cable tray to be tested to the most rigorous military shock and vibrations standards.

    Tests conducted proved that Cablofil Wire Mesh Cable Tray complied to the requirements of MIL Spec-901D.

    Tests were done according to the requirements of:

    • MIL-S-901D Military Specification, Shock Tests, H.I.(High Impact); Shipboard Machinery, Equipment and Systems
    • MIL-STD-167-1 (SHIPS) Military Standards Mechanical Vibrations of Shipboard Equipment


     

    E90 Fire Testing

    Fire tests according to DIN 4102-12: 1998-11

    • Circuit integrity of electrical cable systems

    • Tests whether a complete system (cable+tray+support) can maintain circuit integrity over a defined period of time
      • Duration Label received
        30 minutes E30
        60 minutes E60
        90 minutes E90
      • Types of cables
        • Specific electric cables
        • Specific telecommunications cables

      Fire tests according to DIN 4102-12: 1998-11
    • Requirements
      • Furnace of 3 meters in length, minimum
      • Temperature must follow the standard temperature curve (ETK) according to DIN 4102-12
      • Cables tested by pairs
      • Results:

        Cablofil did not fail after 1-1/2 hours in fire chamber. Cablofil is safer for emergency personnel than J-Hooks or aluminum tray since cable bundles and tray stay up in the ceiling.



        Cablofil Cable Tray: PROVEN to be Corrosion Resistant

        The Requirements:
        According to NEMA VE 1-2002/CSA C22.2 No. 126.1-02, Metal Cable Tray Systems:

        Cable tray systems shall be made of either corrosion-resistant metal, such as aluminium or stainless steel, or metal with a corrosion-resistant finish.

        Carbon steel used for cable trays shall be protected against corrosion by one of the following processes:

        a) Type 1 - Hot-dip galvanizing after fabrication
        b) Type 2 - Hot-dip mill galvanizing
        c) Type 3 - Electrodeposited zinc

        The Results:

        Cablofil's ETL Intertek Testing Report gives "the results of the inspection, tests and evaluation of Metal Cable Trays, for compliance with applicable requirements of the Standard for Metal Cable Tray Systems" (NEMA VE 1-2002/CSA C22.2 No. 126.1).

        This testing report states that Cablofil's "carbon steel used for the cable trays are protected against corrosion".

        Comparison of Various Finishes: Salt Spray Testing

        Tests on metallic protection coatings have proven the superiority of the Stainless Steel wires, in comparison to Electro Zinc and Hot-Dip Galvanized.

        The Salt Spray Test represents typical enviromental corrosion. Tray is subjected to salt spray over a set amount of time, and the resulting corrosion is measured.

        Time EZ (Electro Zinc) GC (Hot-Dip) IN (Stainless)
        120 hours No Rust No Rust No Alteration
        144 hours No Rust No Rust No Alteration

        Seismic Bracing Click Here for Certification

        In California, there are very strict rules for all medical facilities and hospitals. OSHPOD (Office of Statewide Health Planning and Development) is an organization that exists to ensure safety requirements are met in these buildings (their website is www.oshpd.state.ca.us/index.htm.) Cable tray itself doesn't need OSHPOD certification; however, both seismic bracing kits and the supports mounted on the wall or ceiling must be OSHPOD-certified.


        Loos' seismic bracing kits are OSHPOD-certified, as well as Title 24 certified (Title 24 addresses energy efficiency and was released by the California Energy Commission).

         

        Short Circuit Testing
        Cablofil wire mesh tray is the cable management solution for both power and data cables. Cablofil is the only wire mesh tray that has been short circuit tested for use with single conductor power cables. Single conductor power cables are required to be strapped to the cable tray and shor circuit forces can be substaintial. The unique design of Cablofil wires, welded at every intersection distributes the forces and stays intact even during a short circuit. A quick look at the video below proves how robust Cablofil tray is.
