BFOU 0.6/1 kV
NEK 606 offshore fire-resistant power cable, halogen-free, braid armoured
BFOU 0.6/1 kV is the fire-resistant version of RFOU: a mica-tape barrier under the insulation keeps the circuit working in a fire, with circuit integrity to IEC 60331. For emergency and safety circuits on platforms and ships: fire-fighting, emergency lighting, emergency shutdown (ESD) and alarm. Supplied to order; the lead time is stated in the quote.
BFOU 0.6/1 kV is a fire-resistant, flame-retardant, halogen-free and drilling-mud-resistant power and control cable for fixed installation on offshore units, drilling rigs, FPSOs and ships, designed to NEK TS 606 (code P5/P12, now P105) and IEC 60092-353. The tinned copper conductors carry a mica-tape fire barrier under the halogen-free EPR insulation, so that the circuit remains functional during a fire to IEC 60331; the cores are protected by a halogen-free inner sheath, a braid of tinned copper wires and a halogen-free, drilling-mud-resistant thermoset outer sheath. The cable is intended for emergency and safety circuits that must keep operating in a fire, such as fire-fighting, emergency lighting, shutdown and alarm systems, as well as general power, lighting and control circuits below 1 kV in safe and hazardous areas, including locations exposed to oil, drilling fluids and drilling mud.
Also known as: fire-resistant offshore cable
Applications
- Emergency and safety circuits that must keep operating in a fire.
- Fire-fighting, emergency lighting, shutdown and alarm systems offshore.
- General power, lighting and control circuits below 1 kV in safe and hazardous areas.
What to look out for
- Circuit integrity to IEC 60331 applies to the cable; brackets, penetrations and terminals must survive the same fire time, or the circuit fails anyway. Metal brackets, no plastic.
- For circuits without circuit integrity, RFOU is sufficient and more cost-effective.
- Conductor
- Tinned annealed stranded circular copper, class 2 acc. to IEC 60228. Class 5 (flexible) on request.
- Fire barrier
- Mica-glass tape applied over the conductor.
- Insulation
- Halogen-free EPR compound.
- Inner sheath
- Halogen-free, flame-retardant compound.
- Armour
- Braid of tinned copper wires.
- Outer sheath
- Halogen-free, flame-retardant and drilling-mud-resistant thermoset compound (SHF2), black.
- Core identification
- Up to 4 cores: coloured cores acc. to NEK TS 606; 5 cores and more: white cores with black numbers.
- Rated voltage Uo/U
- 0.6/1 kV (max. operating voltage 1.2 kV).
- Test voltage
- 3.5 kV.

BFOU or BU?
BFOU 0.6/1 kV
- inner sheath and tinned braid
- mechanical protection and screen
BU
- unarmoured
- lighter and more flexible
Both are fire-resistant: a mica tape under the EPR insulation keeps the circuit working in a fire to IEC 60331-21. BFOU also has an inner sheath and a braid of tinned copper wires, for mechanical protection and as a metallic screen. BU is unarmoured and therefore lighter and more flexible. Choose BFOU where the cable can be damaged or a screen is needed, and BU on protected routes.
View BU 0.6/1 kV →BFOU 0.6/1 kV or BFOU(c) 250 V?
BFOU 0.6/1 kV
- power cable below 1 kV
- emergency lighting and extinguishing systems
BFOU(c) 250 V
- instrumentation cable
- measuring, control and alarm signals
Both keep the circuit working in a fire. BFOU 0.6/1 kV is the power cable for emergency and safety circuits below 1 kV, such as emergency lighting and fire-extinguishing systems. BFOU(c) 250 V is the instrumentation cable with twisted pairs under a collective screen, for measuring, control and alarm signals. Power therefore runs over BFOU 0.6/1 kV, and signals that must keep working in a fire over BFOU(c).
