Rebecca Longhurst, Marketing & Sales Support at Securi-Flex, identifies some of the benefits of utilising H07RN-F cables for industrial and commercial power-based applications.
H07RN-F cable stands out as a reliable and versatile option when it comes to efficient transmission of power, mainly thanks to its durability, flexibility and resistance to harsh environmental conditions.
A heavy-duty rubber-insulated and sheathed cable, it is primarily designed for use in industrial environments, construction sites and other demanding applications. The main function of a H07RN-F cable is for power supply and control purposes where flexibility, robustness and resistance to mechanical stress are paramount.
The “H” signifies “Harmonised”, meaning that it conforms to European Standards set by CENELEC (the European Committee for Electrotechnical Standardisation). The “07” denotes the voltage rating of 450/750 V, whilst the “RN” represents the rubber insulation and sheath. Lastly, the “F” denotes the cable’s suitability for fixed installation (although it’s often used in flexible applications as well).
Construction and design
The conductor is typically made of stranded copper wires, offering excellent conductivity and flexibility. The stranding ensures that the cable can withstand bending and twisting without compromising its performance. The insulation layer is made of synthetic rubber (usually EPR – Ethylene Propylene Rubber), providing electrical insulation and resistance to high temperatures.
Finally, the outer sheath is also made of robust rubber material, offering protection against mechanical damage, moisture, oils, and chemicals. This sheath is what gives the cable its durability, allowing it to withstand harsh environmental conditions.
Features and benefits
H07RN-F cables offer flexibility, which enables easy installation, even in restricted tight areas and complex layouts. They’re also highly resistant to abrasion, impact and prolonged exposure to environmental factors such as sunlight, moisture and chemicals.
The cables are designed to operate effectively across a broad temperature range, making them suitable for both indoor and outdoor applications.
Applications include constructions sites, outdoor events and concerts, industrial machinery and equipment, power distribution in factories and warehouses and temporary power installations.
H07RN-F cables are a reliable and versatile solution for demanding electrical applications where flexibility, durability, and resistance to harsh conditions are essential. Whether it’s powering heavy machinery on a construction site or providing temporary light for an outdoor event, these cables excel in ensuring safe and efficient power transmission.
