H05RR-F Cable: Light-Duty Rubber Cable
Construction & Ерекше өзгешеліктері
H05RR-F cables consist of fine-stranded copper conductors, резеңке оқшаулау, and an outer sheath made of ordinary rubber. These cables are highly flexible and are designed for light-duty applications.

Voltage Rating
H05RR-F cables have a voltage rating of 300/500В, making them ideal for low-voltage applications.
Mechanical Strength & Durability
These cables are designed to withstand light mechanical stress but are not suitable for harsh environments or heavy-duty industrial applications.
Қолданбалар
H05RR-F cables are commonly used in: Household appliances, Light workshop tools, Handheld equipment, Temporary outdoor setups (under minimal stress conditions)
Due to their limited mechanical strength, they should not be used in applications exposed to oils, chemicals, or extreme environmental conditions.
H05RN-F Cable: Medium-Duty Rubber Cable
Construction & Ерекше өзгешеліктері
H05RN-F cables are built with резеңке оқшаулау and a neoprene sheath (chloroprene rubber), which enhances their resistance to oil, chemicals, and mechanical stress compared to H05RR-F cables.
Voltage Rating
H05RN-F cables also have a voltage rating of 300/500В, similar to H05RR-F.
Mechanical Strength & Durability
These cables are designed for medium mechanical stress and can withstand moderate levels of movement, bending, and external impacts.
Қолданбалар
H05RN-F cables are ideal for: Kitchen appliances, Medium-duty industrial tools, Workshop power tools, Equipment exposed to light oil and chemical contact
Their neoprene sheath makes them more durable than H05RR-F, allowing usage in environments where minor exposure to oils and mechanical wear is expected.
H07RN-F Cable: Heavy-Duty Rubber Cable
Construction & Ерекше өзгешеліктері
H07RN-F cables are composed of резеңке оқшаулау with a neoprene sheath, offering superior resistance to mechanical stress, oils, chemicals, UV radiation, and harsh weather conditions.

Voltage Rating
H07RN-F cables are rated for 450/750В, which makes them suitable for higher power industrial applications.
Mechanical Strength & Durability
These cables are built for heavy mechanical stress and can endure rough handling, frequent bending, and exposure to extreme conditions. Their rugged nature makes them ideal for demanding environments.
Қолданбалар
H07RN-F cables are widely used in: Industrial machinery and equipment, Construction sites, Agricultural applications, Outdoor installations and mobile power units, Marine and shipboard applications
Their durability and flexibility make them the preferred choice for environments requiring high mechanical resilience and electrical reliability.

How to Choose the Right Rubber Cable?
Users should consider the following factors when selecting the right rubber cable:
- Voltage Requirements: Make sure the cable meets the voltage specifications for the project application.
- Environmental Conditions: If the cable is exposed to oils, chemicals or outdoor environments, it is best to select a neoprene sheathed cable (H05RN-F or H07RN-F).
- Mechanical Stress: Determine whether the cable will be subjected to light, medium or heavy mechanical stress and choose accordingly.
- Flexibility Requirements: If the application environment requires frequent bending and movement, select a cable with a highly flexible design, such as H07RN-F.
For other uncertain selection factors, please feel free to consult ZMS Cables.
