Huber+Suhner has launched a fire-resistant version of its Radox cable system for offshore applications.

The Radox OFL  (Oil & Gas Flexible Lightweight) cable reduces weight and space by up to 60 percent compared to other cables on the market. The cable’s small bend radius and thin wall – which is half the size of standard cables – reduces stripping time by 60 percent, making installation easier and quicker. This has the potential to save industrial and offshore facilities several hundred thousands of dollars in structural design by overcoming space and weight restrictions.

The OFL cable is highly fire-resistant and low smoke halogen free (LSFH), which provides exceptional performance in harsh outdoor environments and offshore industrial applications. Core cables do not melt or drip in the event of a short circuit, ultimately minimising emergency repairs and the potential for hazardous fume inhalation. The OFL cable is also oil, mud and hydraulic oil resistant according to the highest standard NEK606 Cat. a-d.

In addition, the Radox technology offers a 120°C sheath and 145°C core temperature threshold, giving the cable an expected lifetime which is eight times longer than standard 90°C offshore cables. The polymers in the insulation of the wires and in the cable sheath are cross-linked using electron beams which provides resistance to mechanical, chemical, temperature and weather influences.

“The offshore industry presents challenging conditions, including high temperatures, oil, chemicals and UV radiation. This means cables have to be robust and stand the test of time. The latest RADOX OFL cable does exactly this, while also reducing installation time and reducing weight, making it a valuable investment that can future-proof offshore connectivity,"said Frank Thorn, Head of Market Unit Industry, Low Frequency division of Huber+Suhner.

The smaller diameter means smaller cable accessories such as connectors and trays can also be used, further reducing space, weight and cost in monitoring and control, as well as sensor applications on offshore platforms.

“Offshore applications require durable, flexible and reliable cables that can operate seamlessly and withstand harsh environments to avoid deterioration," added Thorn. "We developed the Radox OFL cable
