Composite Cable Trays – The Best Fire Resistance Technology
When fire starts, the basic need is to stop or reduce its propagation and extinguish it if possible. Several fire retardant systems including GRP cable trays have been developed by cable industry to ensure safety of workforce. These systems prevent spreading of fire and major loss when the fire is out of control. Special devices are being installed to alert people to EXITs. And these devices must be connected to the power network. Fire resistant cables are often applied for power connections and they function as active elements since they have to maintain continuity of electricity for an adequate amount of time. Fire retardant cables are produced by using three main technologies. Initial designs were based on copper conductors that were wrapped in mica tape and cross-linked polyolefin. Today, manufacturers combine the benefits of mica and silicone rubber conductors excluding their limitations.
