Overview: The TEBAOFLEX 0.6/1kV RFOU cable (along with RFBU, RFCU, and BFOU variants) is a premium double-braided, flame-retardant, and halogen-free power cable. It is specifically engineered for extreme marine and offshore environments.
Key Specifications:
- Approvals & Standards: Complies with IEC 60092-353, IEC 60332, IEC 60754, and IEC 61034.
- Extreme Resistance: Outstanding Oil & Mud resistance meeting the strict NEK 606 requirement.
- Temperature Range: Withstands severe cold environments with cold bend/impact resistance at -40°C / -35°C (CSA 22.2 0.3-01 & IEC 60092-350).
- Application: Fixed installation for power, control, and lighting in both EX- and safe areas on offshore platforms and ships.
The Ultimate RFOU Cable for Extreme Marine and Offshore Environments
When operating in the middle of the ocean, the safety and reliability of your electrical infrastructure cannot be compromised. The TEBAOFLEX 0.6/1kV RFOU cable is an industry-leading, flame-retardant, and completely halogen-free power cable. It is double-braided and explicitly designed for fixed installations in some of the most demanding offshore environments worldwide, ensuring continuous power, control, and lighting in both EX- (explosion-proof) and safe areas.
Why Choose TEBAOFLEX’s RFOU Cable?
As a professional cable manufacturer, TEBAOFLEX engineers the RFOU cable to withstand the harshest chemical and climatic challenges. One of the most critical features of this cable is its outstanding Oil and Mud resistance, which strictly meets the rigorous NEK 606 requirements for installations exposed to drilling and cleaning fluids. Furthermore, it excels in freezing conditions, meeting the cold bend and cold impact requirements of CSA 22.2 0.3-01 and IEC 60092-350 (Annex E) down to -40°C / -35°C.

Comprehensive Standards and Approvals
Our marine cables, including the RFOU cable, RFBU, RFCU, and BFOU variants, are manufactured and tested according to the highest international maritime standards:
- Design & Conductor: IEC 60092-353 (Design), IEC 60228 class 5 (Flexible Conductor).
- Insulation & Sheath: IEC 60092-360 (EPR Insulation and SHF2 Sheath).
- Flame Retardancy: IEC 60332-1-2 and IEC 60332-3-22.
- Halogen-Free & Low Smoke: IEC 60754-1,2 and IEC 61034-1,2.
Detailed Cable Construction (EPR/EPR/TCWB/EVA)
The structural integrity of our RFOU cable prevents moisture ingress, mechanical damage, and chemical corrosion. The core construction includes:
Conductor: Tinned annealed flexible circular copper (IEC 60228 class 5) to prevent oxidation in salty air.
- Insulation: High-grade EP-rubber (EPR) for excellent electrical properties.
- Inner Covering: Flame retardant and halogen-free thermoset compound (SHF1).
- Armour/Screen: Braid of tinned copper wire (TCWB). *Options for Bronze wire (BFOU) or Galvanized steel wire (RFCU) available.
- Outer Sheath: Heavy-duty Black SHF2 compound, with NEK 606 Category a, b, c, d Mud or oil resistant options.
Core Identification for Power Cables
To facilitate easy and accurate installation on offshore platforms, our RFOU cable series utilizes a standardized core identification system:

Frequently Asked Questions (FAQ)
1. What does the “Mud Resistant” NEK 606 standard mean for this cable?
In offshore oil and gas drilling, cables are frequently exposed to highly corrosive drilling muds and cleaning fluids. An RFOU cable certified to NEK 606 has a specially formulated SHF2 outer sheath that prevents the cable from swelling, cracking, or degrading when submerged or splashed with these caustic hydrocarbons.
2. Can this cable replace RFCU or BFOU cables?
Yes, they are highly related. RFOU utilizes a tinned copper wire braid, while RFCU uses galvanized steel wire, and BFOU uses bronze wire for the armour/screen. Depending on your specific mechanical protection needs and shipyard requirements, our factory can manufacture any of these variants to exact specifications.
3. Are you a trading company or a direct cable factory?
TEBAOFLEX is a direct, certified manufacturer of high-performance marine and offshore cables. We support bulk wholesale orders, custom cross-sections, and project-based manufacturing.
