RFOU cables in Singapore are categorised as marine cables; also known as XAI cables, which are widely used in all manners of emergency and critical equipment ranging from lighting systems to fire warning alarms. XAI is a designation used to indicate marine cables for 1kV power and control, and a capacity of medium voltage up to 30k, and 150/250V instrumentation cables. These cables usually consist of plain copper, tinned copper, and galvanised wire braiding, with an LSZH sheathing or insulation.More Information
RFOU cables are flame-retardant, making them highly effective in high-heat situations and environments. Manufactured according to NEK-606 grade, it has halogen-free properties to accommodate people when they may be endangered by toxic fumes or acid-forming gases in the event of a fire outbreak. RFOU cables are also designed for both offshore and onshore buildings in a marine environment and has an operational temperature range of -40oC to +90oC.
RFOU cables are MUD-resistant, meaning they are exceptionally resistant to hydrocarbons and oils resulting from drilling. This is essential as the cables need to withstand harsh marine working environments. It also has an Ethylene Vinyl Acetate sheathing that is rated SFH2 and certified by NEK-606. Its main conductors are tinned annealed stranded copper, and its cores can be identified by series of colours.
The application of RFOU power cables is commonly used in fixed installations to connect power, control, and lighting in both EX (Zone 0,1 & 2) and safe areas, general purposes. For Installation in areas exposed to MUD and drilling/ cleaning fluids.
