Axelent - X-Tray

9 8 * When a fire breaks out it is vital that certain things carry on functioning. This could involve the activation of alarm systems, emergency lighting, sprinkler systems and smoke detectors, or other things that could save lives during a fire. This could be a long list. It is always a good thing for cable trays to withstand a fire for as long as possible. The German DIN 4102-12 standard is used for testing this, a standard that is designed to test complete systems of cable trays, accessories and cables. Cable trays and cables are put in an oven and heated for 90 minutes until the temperature has reached 1000°C. To be approved, the cables must still be in a usable condition. Approval comes in three classes: E30, E60 and E90 or for how many minutes the cable trays and cables are still functional. X-Tray has been approved at the highest class, E90. We carried out the test at IBMB (Institut für Baustoffe, Massivbau and Brandshutz) in Brauswieg, Germany. IBMB is a prestigious, independent testing institute that issued the approval in accordance with the DIN 4102-12 standard. The trays, brackets and cables were approved together. We have tested several batches of cable trays in combination with several different cables. Tested for equipotential bonding in compliance with IEC61537 Find out more about our tests at www.axelent.com As well as IEC 61537, we have also tested and certified our trays in the following areas: material, welding, load, identification, EMC, surface treatment, vibrations and fire. In some installations the cable tray needs to be equipotentially bonded. This is to secure protective bonding or functional bonding. Protective bonding The main reason for protection bonding is to protect against electrical points of contact that could be caused by faults in the electrical system. This is remedied by connecting the cable tray to the main earth terminal in the building. Functional bonding This is done to minimise the impact of electrical and magnetic fields (EMC). It is carried out in the same way as with protective bonding, i.e. by connecting the cable tray to the main earth terminal in the building. Requirements and tests The IEC 61537 standard lays down the requirements placed on a cable tray to ensure electrical continuity. Among other things, the impedance must not exceed 50 mOhm over joints or 5 mOhm X number of metres of cable tray. X-Tray has been tested and complies fully with IEC 61537. The tests were conducted by the Research Institute of Sweden (SP) with test report numbers PX16030 and 5F015879. NB. X-Tray cable trays must never be used as protective bonding conductors, earth conductors or any other type of protective conductor.
