The H07RN-F 3G2.5 cable is one of the most widely used heavy-duty rubber flexible cables in industrial and outdoor environments. Known for its durability, flexibility, and resistance to harsh conditions, it is commonly used for power supply in construction sites, generators, and portable equipment.
This article provides a complete overview of H07RN-F 3G2.5 cable, including its specifications, features, applications, and how to choose the right supplier.
H07RN-F 3G2.5 cable is a harmonized European standard rubber cable designed for heavy-duty applications. It consists of three conductors, including a protective earth wire, with each conductor having a cross-sectional area of 2.5 mm².
The cable features flexible copper conductors, EPR rubber insulation, and a neoprene outer sheath, making it suitable for demanding environments where mechanical stress and environmental exposure are common.
The name “3G2.5” provides important technical information:
“3” indicates three cores
“G” means the cable includes a green/yellow earth wire
“2.5” refers to the conductor size of 2.5 mm²
This configuration makes it ideal for single-phase power supply with grounding protection.
H07RN-F 3G2.5 cable typically includes the following specifications:
Rated voltage: 450/750V
Conductor: Class 5 flexible copper
Insulation: EPR (Ethylene Propylene Rubber)
Outer sheath: Neoprene rubber
Temperature range: -30°C to +60°C
Current rating: approximately 32–36A
These parameters ensure reliable electrical performance and durability in both indoor and outdoor applications.
One of the main advantages of H07RN-F 3G2.5 cable is its excellent flexibility. The fine-stranded copper conductors allow easy installation and repeated movement without damage.
The cable is designed for heavy-duty use and can withstand mechanical stress such as bending, dragging, and vibration. Its neoprene outer sheath provides strong resistance to oil, chemicals, abrasion, and UV exposure.
In addition, the cable is waterproof and suitable for use in wet environments. Its flame-retardant properties also enhance safety in industrial applications.
H07RN-F 3G2.5 cable is widely used in a variety of industries and environments, including:
Construction sites for temporary power distribution
Generator connections for backup or mobile power
Portable tools and electrical equipment
Outdoor installations exposed to weather
Industrial machinery and production lines
Water pumps and drainage systems
Its versatility makes it one of the most commonly selected rubber cables for medium-duty power requirements.
Compared to standard PVC cables, H07RN-F 3G2.5 cable offers several advantages. It has better flexibility, especially in low temperatures, and superior resistance to mechanical damage.
The rubber insulation and sheath provide enhanced protection against environmental factors such as moisture, oil, and UV radiation. This results in a longer service life and lower maintenance costs in demanding conditions.
When selecting an H07RN-F 3G2.5 cable, consider the following factors:
Verify compliance with standards such as EN 50525
Check conductor quality and material purity
Confirm the cable’s current rating matches your application
Evaluate the supplier’s certifications and experience
Ensure availability of technical support and datasheets
Choosing a reliable supplier is essential for ensuring consistent quality and performance.
The H07RN-F 3G2.5 Cable is a reliable and versatile solution for industrial and outdoor power applications. Its combination of flexibility, durability, and resistance to harsh environments makes it a preferred choice for professionals worldwide.
Whether used on construction sites, generators, or industrial equipment, this cable delivers stable performance and long-term reliability.
