Prysmian BFOU(i) 8×2×0.75 mm² is a halogen-free, flame-retardant instrumentation cable with eight individually screened twisted pairs and an overall diameter of 21.5 mm. The 0.75 mm² tinned-copper conductors carry low-level signal, control or data circuits in marine and offshore installations conforming to IEC 60092-350/353. The blue outer sheath is generally used to designate intrinsically safe circuits.
