Intumescent coatings are reactive fire-protection paints applied to the tray surface—often factory-applied to control thickness and quality. Under fire exposure, the coating expands to form an insulating char layer, slowing heat transfer. ALTIC 007 is a water-based, intumescent fire retardant coating designed for cables, cable trays, and penetrations, providing up to 4 hours of certified circuit integrity as per NTH Mumbai testing. Our products, ideal for contractors, painters, and new businesses, meet fire and building codes, ensuring safety against fire risks in construction projects. So, what exactly is fire retardant. Most EPC specifications narrow the choice to two mainstream solutions: fire wrap systems (encapsulation) and intumescent fire-resistant coatings (reactive coatings).

Electrostatic interference is caused by stray capacitance between the control signal cable and other conductors and machinery in the area. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require. This article will explain the thermal and electromagnetic factors affecting cable ampacity in tray installations, discuss various calculation methods (analytical and numerical), summarise the standards including IEC 60287, and outline three different methods for calculating the ampacity of cables. (i) Metal raceways, cable trays, cable armor, cable sheath, enclosures, frames, fittings, and other metal noncurrent-carrying parts that are to serve as grounding conductors, with or without the use of supplementary equipment grounding conductors, shall be effectively bonded where necessary to. Any break in a conductive enclosure – a cable entry, a ventilation slot, a connector port – is a potential source or entry point for electromagnetic interference. Learn our precise method for installing a low-impedance grounding system.
