In addition to mechanical and electrical tests, cables are often also subjected to fire tests (the CPR Regulation is proof of this). The most common test is the flame retardancy. In fact, each cable sold must comply with certain resistance standards that vary according to the country of installation.
In the video we made at the laboratories of La Triveneta Cavi, we illustrate two ways to carry out the test, but according to different countries that require different requirements of the test: the one in force in the European Union, EN 60332-1-2 and the one used for North America, UL 2556.
Both have the same purpose but different methodology. In the European test EN 60332-1-2 the cable must be subjected to a continuous flame for a time determined according to the diameter of the cable. In the American test EN 60332-1-2 instead, the cable must undergo a series of cycles where the flame is applied and then removed.
Both cables tested have successfully passed the two tests; it is very interesting to visually observe the exceptional performance of the FG17, designed to withstand in these harsh conditions with a very low flame propagation.
The endless search for innovative solutions, to improve the performance of energy accumulators, is leading the whole world of home automation into unexplored areas. In fact, Stanford University has recently announced, the surprising innovative results related to aluminum-ion batteries. This technology will be replacing alkaline batteries and lithium-ion batteries, that are currently sold on the market.…Read more
