H07RN-F cable is a highly flexible and weather resistant rubber insulated flexible cable for a wide range of electrical connection needs. It contains many applications varying from the indoor uses to the outdoor uses. Due to the cable’s oxygen permeation, it is usable and mechanically resistant even in extreme heat, water, wind, and chemical environments. Compared to the H05RN-F, the H07RN-F cable has a higher voltage rating of 450/750V, which guarantees high power reliability under such harsh conditions. Let’s examine the H07RN-F cable and its applications.
H07RN-F cable meaning follows the standardized European regulations.
H- Harmonized
07- 450/750volts
R- EPR （Ethylene Propylene Rubber )
N – PCP (Polychloroprene)
F – ( fine wire flexible cord )
Construction and Material Properties
Composition of H07RN-F cable
Conductor: Stranded with multiple strands of fine copper wire, this construction improves the flexibility of the cable, allowing for better shape adaptation when bending, conforming to the requirements of DIN VDE 0295 and IEC 60228 standards for high category conductors, usually oxygen-free pure copper, annealed to increase flexibility and reduce resistance.
Insulation: The use of the high mechanical properties of the rubber material EPR (Ethylene Propylene Rubber) provides good electrical insulation, while ensuring stability and durability in harsh environments. This insulation is resistant to high and low temperatures, oil and chemical attack.
Sheathing: The outer layer is usually a reinforced PCP (Polychloroprene) sheath providing additional mechanical protection against oils and chemicals, as well as certain flame retardant properties.
Properties of H07RN-F cable
Insulation and Temperature Resistance: High-quality rubber as regards used as insulation materials can operate temperature -20°C to +90°C which is appropriate for dry, wet, outdoor and even some extreme conditions.
Mechanical Properties: It is rugged and is constructed to withstand mechanical impact and shock, such as abrasion and compression, which makes it ideal for interfacing and connecting with mobile equipment and machines.
Chemical Resistance: Despite good principles of H07RN-F cables giving them wide applicability, it is advisable to restrict exposure of the cable to a limited amount of specific chemicals such as mold release compounds, certain glues and grease.
Installation characteristics: There is good bending radius which accommodates simple installation on such equipment where there is limited free space or such where frequent movement is needed.
Flame retardancy: It passes flame retardancy tests ion IEC 60332-1-2 and similar to prevent fast spread of fires in case they occur thereby improving safety.
H07RN-F Cable Application
Industrial Environment
- Factories and Manufacturing Plants
Industrial Equipment: H07RN-F cable in industrial environment is very flexible and can withstand mechanical pulls, these cables are mainly used to connect mobile power and handling equipments. For instance, it can be used to connect mobile cranes, forklifts and such other movable equipments inside a factory.
- Construction sites
Building electrical installations: Whether for permanent or temporary buildings, such as temporary power supply systems on construction sites, H07RN-F cable is ideal for electrical installations due to its weatherproof and fireproof characteristics. It can adapt to the harsh conditions during building construction while meeting safety standards.
Outdoor applications
- Outdoor and special environment applications
In harbor area, street, stage lighting, audiovisual arrange and wind power generation facilities, the H07RN-F cable has effective water, oil and weather proof. Due to extreme weather and complex conditions, these cables ensure the proper transmission of electric power. In wind power generation, this cable is mainly used as rotor connection cable withstanding mechanical dynamic stress and climate conditions inside wind generator.
- Explosion-hazardous areas
In areas where there is a risk of explosion, such as chemical plants and gas stations, the flame-retardant and chemical-resistant properties of H07RN-F cables make them the choice for safe connections, reducing the risk of potential sparks and safeguarding personnel and equipment.

The above is a detailed specification and current-carrying capacity table for H07RN-F cables. The table is intended to help us determine the appropriate cable based on the number of cores and nominal cross-sectional area. Also the maximum continuous operating temperature for conductors during normal use varies depending on the type of installation. For mobile installations, the temperature should not exceed +60°C. In fixed and protected installations, the maximum is +85°C. During short circuits, conductors can withstand temperatures of up to +200°C.
The H07RN-F cable remains a preferred option across various applications. The construction is stable and flexible under extreme conditions. Also the H07RN-F cable offers long-term use with minimal maintenance. High resistance to wear extends the cable’s lifespan. Regular inspections ensure optimal performance.
