One of the frequently asked questions that our team receives is what is the difference between RFOU and BFOU cable? Below we are going to explain the main difference between these two popular offshore cables.
What are RFOU and BFOU cables?
In simple words, they are armored and sheathed cables designed for the most demanding marine and offshore harsh environments applications.
RFOU and BFOU are categorized as instrumentation and power cables commonly used for telecommunications, and fixed installation in various electromechanical and electronic equipment, emergency, critical systems, and lighting systems.
These cables have similar structures and are made of similar materials, both protect human life and equipment during a fire and are halogen-free thermosetting compound SHF2 or SHF Mud sheathed. But, there is one main difference between them.
It is important to mention that both cables are made in accordance with the NEK 606 technical specification standard widely adopted in Europe and in many other countries around the world.
RFOU and BFOU cables follow the IEC 60092-350, -360, and -370 series. The compliance standards required for the most demanding marine and offshore applications.
RFOU and BFOU Difference
The main difference is that RFOU cables are made with flame retardant capability following the IEC60332 Flame Retardancy standard while the BFOU has an additional fire-proof Mica Glass Tape (MGT) that acts as a fire barrier over the conductor to provide uninterrupted power or signals during a fire situation.
RFOU Cable Specification
RFOU cable is best for instrumentation, communication, control, and alarm systems. This type of cable provides low smoke density which reduces the risk of suffocation and keeps visibility around the fire zone.
EUTEX offers a wide variety of RFOU cables with options from low to high-voltage applications.
BFOU Cable Specification
BFOU cable has fire resistance, low smoke, halogen-free, and mud resistance features which make it the best option for the most demanding offshore applications. These cables are made for high performance where the conditions are harsh, for example, extreme heat, cold, humidity, oil vibration, salt corrosion, etc. This type of cable has an additional fire-proof Mica Glass Tape (MGT) that acts as a fire barrier over the conductor to provide uninterrupted power or signals during a fire situation.
