Prysmian BFOU(i) 2×2×1.5 mm² is a halogen-free, flame-retardant instrumentation cable with two individually screened twisted pairs and a 17 mm overall diameter. Each 1.5 mm² tinned-copper conductor is dimensioned for signal, control and data circuits on ships and offshore installations conforming to IEC 60092-350/353. The blue outer sheath is used to identify intrinsically safe circuits.
