Cables, often referred to as the "blood vessels" of power transmission, play a critical role in various equipment and systems. However, not all cables are designed to withstand extreme working conditions. In environments with high temperatures, humidity, oil contamination, or even potential fire hazards, standard cables may face issues such as insulation aging, performance degradation, and safety risks. So, how can you select a reliable and durable cable for these demanding conditions to ensure stable power system operation?

This article focuses on the H05 RN-F SUPremeFlex rubber cable, providing an in-depth analysis of its design features, performance advantages, and suitable applications. It serves as a professional selection guide to help you choose the most appropriate power solution for complex environments.

The H05 RN-F SUPremeFlex rubber cable is a harmonized European-standard cable with a rated voltage of 300/500V. Its unique design and material selection make it an ideal choice for reliable power transmission in various challenging environments.

• Conductor: Utilizes electrolytically annealed Class 5 bare copper strands (tinned copper strands available upon request). The multi-strand design provides excellent flexibility for easy installation and mobile use. High-purity copper ensures superior conductivity and reduces energy loss.
• Insulation: Features EI4-type rubber (EPR) compound. EPR (Ethylene Propylene Rubber) offers exceptional heat resistance, weather resistance, chemical corrosion resistance, and electrical insulation properties, maintaining stable performance even in high-temperature or humid environments. Compared to PVC insulation, rubber insulation is more elastic, less prone to cracking, and has a longer service life.
• Core Identification: Color-coded according to HD 308 standards for easy installation and maintenance, preventing wiring errors.
• Outer Sheath: Made of EM2-type elastomer compound. EM2 elastomer provides excellent oil resistance, abrasion resistance, and weather resistance, effectively protecting the cable from external environmental damage. The black sheath (other colors available upon request) offers superior UV resistance, making it suitable for outdoor use.

The H05 RN-F SUPremeFlex rubber cable excels not only in material selection but also in performance, meeting the demands of various harsh environments.

• Temperature Resistance: Maximum conductor working temperature of 60°C, short-circuit temperature of 200°C, and maximum cable surface temperature of +50°C. This ensures stable operation in high-temperature environments without premature aging or damage.
• Cold Resistance: Minimum installation temperature of -25°C. The cable maintains excellent flexibility even in cold conditions, facilitating installation and use.
• Flame Retardancy: Complies with EN/IEC 60332-1-2 and DIN VDE 0482-332-1-2 standards, offering excellent flame-retardant properties. The cable self-extinguishes in case of fire, reducing the risk of fire spread.
• Oil Resistance: Meets HD/EN/IEC 60811-2-1 and DIN VDE 0473-811-2-1 standards, providing superior oil resistance for long-term use in oily environments without corrosion or damage.
• Weather Resistance: Features excellent ozone resistance, tear resistance, and UV resistance, making it suitable for long-term outdoor use without aging or deterioration.
• Bending Radius: Minimum bending radius complies with HD 516 Tab.7c standards, allowing for easy installation in confined spaces.

Thanks to its exceptional performance, the H05 RN-F SUPremeFlex rubber cable is widely used in various demanding environments, including:

• Industrial Workshops: Ideal for connecting industrial equipment such as machine tools, welding machines, and lifting devices. Its oil resistance, abrasion resistance, and high-temperature tolerance meet the harsh demands of industrial environments.
• Agricultural Settings: Suitable for agricultural equipment like irrigation systems and feed processing machines. Its weather resistance, cold resistance, and chemical corrosion resistance address the challenges of agricultural environments.
• Kitchens: Perfect for kitchen appliances such as ovens, microwaves, and dishwashers. Its high-temperature resistance and flame-retardant properties ensure safe electrical use in kitchens.
• Offices: Ideal for connecting mobile office equipment like printers, copiers, and computers. Its flexibility and safety features meet office electrical needs.

When selecting the H05 RN-F SUPremeFlex rubber cable, consider the following factors:

• Conductor Number and Cross-Sectional Area: Choose the appropriate conductor number and cross-sectional area based on the equipment's power and current requirements to ensure safe and reliable power transmission. Refer to the specification table for guidance.
• Working Environment: Select a cable with suitable performance characteristics based on environmental factors such as temperature, humidity, and oil exposure.
• Installation Method: Choose a cable that matches the installation method. For example, opt for a highly flexible cable for frequently moved applications.
• Certification Standards: Ensure the cable complies with relevant certification standards, such as European harmonized standards, to guarantee quality and safety.
