• 07: Rated for 450/750V.

Р: Stands for a rubber insulation.​

R or N: Indicates the type of sheath material.·

• Р: Ordinary rubber.​
• Н: Chloroprene rubber (neoprene), known for enhanced oil and chemical resistance.·

Ф: Signifies a flexible cable suitable for frequent bending and movement.

H05RR-F Cable: Light-Duty Rubber Cable

Construction & Features

H05RR-F cables consist of fine-stranded copper conductors, Резина изоляциясы, and an outer sheath made of ordinary rubber. These cables are highly flexible and are designed for light-duty applications.

Voltage рейтинги

H05RR-F cables have a voltage rating of 300/500В, making them ideal for low-voltage applications.

Mechanical Strength & Узактыгы

These cables are designed to withstand light mechanical stress but are not suitable for harsh environments or heavy-duty industrial applications.

Тиркемелер

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 & Features

H05RN-F cables are built with Резина изоляциясы and a neoprene sheath (chloroprene rubber), which enhances their resistance to oil, chemicals, and mechanical stress compared to H05RR-F cables.

Voltage рейтинги

H05RN-F cables also have a voltage rating of 300/500В, similar to H05RR-F.

Mechanical Strength & Узактыгы

These cables are designed for medium mechanical stress and can withstand moderate levels of movement, bending, and external impacts.

Тиркемелер

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 & Features

H07RN-F cables are composed of Резина изоляциясы with a neoprene sheath, offering superior resistance to mechanical stress, oils, chemicals, UV radiation, and harsh weather conditions.

Voltage рейтинги

H07RN-F cables are rated for 450/750В, which makes them suitable for higher power industrial applications.

Mechanical Strength & Узактыгы

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.

Тиркемелер

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:

1. Voltage Requirements: Make sure the cable meets the voltage specifications for the project application.
2. 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).
3. Mechanical Stress: Determine whether the cable will be subjected to light, medium or heavy mechanical stress and choose accordingly.
4. 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.

Understanding the differences between H05RR-F, H05RN-F, and H07RN-F rubberized flexible cables is critical to selecting the right cable.H05RR-F is best suited for light-duty applications, H05RN-F offers medium durability, and H07RN-F is ideal for heavy-duty industrial applications.

Users can ensure optimal performance and longevity of electrical installations by taking into account the differences in voltage ratings, mechanical stress and environmental resistance of each cable type. When you need high-quality rubber cables for industrial or commercial use, be sure to choose a reliable supplier that meets international safety standards.
