H07RN-F cable is a highly flexible, heavy-duty rubber cable designed for use in harsh industrial environments. With its durable construction and resistance to chemical, mechanical, and thermal stresses, this versatile cable is commonly employed in applications ranging from mobile power supplies and construction sites to audio-visual equipment and severe agricultural settings.

Cable Code Meaning

The designation H07RN-F is a standardized code that provides key information about the cable’s characteristics and construction:

• H: Harmonized cable, conforming to CENELEC standards
• 07: Rated voltage of 450/750V
• R: EPR (Ethylene Propylene Rubber) insulation
• N: PCP (Polychloroprene) outer sheath
• F: Flexible copper conductor (Class 5)

This coding system allows for quick identification of the cable’s properties, ensuring it meets specific requirements for various industrial applications. The flexibility, voltage rating, and durable construction indicated by this designation make H07RN-F cables suitable for a wide range of demanding environments and uses.

Applications in Extreme Environments

H07RN-F cables excel in extreme environments due to their robust construction and exceptional durability. These cables are designed to operate effectively across a broad temperature range, from -25°C to +60°C for fixed installations and up to +85°C for flexible installations. This makes them ideal for outdoor applications, construction sites, and industrial settings where exposure to harsh weather conditions is common. The cable’s resistance to UV radiation, moisture, and chemicals allows it to withstand prolonged exposure to environmental stressors.

In the wind power industry, H07RN-F cables are particularly valuable, as they can withstand high wind speeds, extreme temperatures, and high humidity while providing the necessary flexibility for suspended installations in wind turbines.

Construction Materials and Properties

H07RN-F cables are constructed with fine-stranded copper conductors, providing excellent flexibility and electrical conductivity. The insulation is made of high-quality Ethylene Propylene Rubber (EPR), which offers superior electrical insulation and thermal stability. The outer sheath consists of Polychloroprene (PCP), a synthetic rubber known for its resistance to oils, chemicals, UV radiation, and weathering.

This robust construction results in a cable that is:

• Highly flexible, allowing for easy installation in tight spaces and complex layouts
• Resistant to abrasion, impact, and mechanical stress
• Capable of withstanding temperatures from -25°C to +60°C in normal use, and up to +85°C in fixed protected installations
• Oil-resistant and flame-retardant, meeting IEC/EN 60332-1-2 standards
• Suitable for both indoor and outdoor applications due to its weather resistance and durability

Core Identification and Configurations

H07RN-F cables are available in various core configurations to suit different applications. The core identification follows standardized color coding for easy recognition:

• Single core: Black
• 2 core: Blue and Brown
• 3 core: Blue, Brown, and Green/Yellow
• 4 core: Black, Brown, Grey, and Green/Yellow
• 5 core: Black, Blue, Brown, Grey, and Green/Yellow

For cables with 6 cores and above, the cores are typically black with white numbers, including a Green/Yellow earth core. This standardized color coding ensures proper installation and helps prevent wiring errors across different industrial applications.

H07RN-F cables are commonly available in cross-sectional areas ranging from 1.5mm² to 25mm² or more, with the number of cores varying to accommodate specific power and control requirements.
