Extreme H07RN-F 90°C HOFR submersible flex is available in single or multicore formats. HOFR = heat & oil resistant, flame retardant rubber. They are designed for trailing or mobile power supply applications in extreme environments including submersion in water. Commonly used in generators, portable equipment, moving machinery, handling equipment & underwater pumps.
This cable is suitable for indoor or outdoor applications including in permanently submersed installations. For example in port areas, dams, drainage or water treatment works, water features, oily or refrigerated conditions.
These Extreme H07RN-F 90°C HOFR cables are ideal for power transmission in both fixed or flexible installations. Nominal voltage up to 1000V is accepted in fixed protected assemblies.
Type EM2 Thermosetting Rubber Properties: this self-extinguishing compound has excellent resistance to oxygen, UV, ozone & water and very good resistance to acids, alkalis & solvents. It also has excellent abrasion resistance.
