FRP cable trays are typically designed with reference to NEMA VE 1 and IEC 61537 load-rating methods. The exact support spacing depends on tray width, rung spacing, cable load, and laminate stiffness. Because FRP has lower modulus than steel, support spans usually need to be. 2. Minor fabrication detail changes which do not affect the material /dimensional aspect of the equipment. FRP cable tray is the support system for managing cables and protect cables from heating, rains and corrosive elements. There are two types, FRP ladder type cable tray and FRP channel cable tray. Compared with traditional galvanized steel trays, FRP cable trays are lighter in weight, corrosion resistant, non-magnetic and electrically insulating, which makes them ideal for chemical. four-bolt pattern for 3, 4, 6 and 8" tray depths FCT cable tray made of corrosion resistant fibre reinforced plastic, comes in standard height of 50mm and 80mm.
