Rubber Cable

Rubber Flexible Cable

Rubber flexible cables are most commonly of heavy-duty variety. A Rubber-sheathed cable is a type of cable which normally consists of a black outer sheath of rubber with several conductors inside. They are sheathed with a thick layer of rubber allowing them to withstand the mechanical stress that normal cable can’t.

A combination of robustness and flexibility makes rubber insulated cables ideal to provide power supply to portable electrical equipment and devices. The mechanical stresses involved in moving apparatus require cables to withstand a high degree of wear and tear.

Decode the cable type:H07RN-F

What is H07RN-F ?

H07RN-F is a type of rubber insulated flexible cable that is commonly used for power transmission in harsh environments. It is designed to be durable and resistant to abrasion, moisture, and chemicals, making it ideal for use in applications where standard PVC cables would not be suitable.

What is the meaning behind H07RN-F ?

The “H” in H07RN-F stands for harmonized, which means that the cable meets European standards for electrical cables. The “07” refers to the voltage rating of the cable, which is 450/750 volts. The “RN” stands for rubber insulated, neoprene sheathed, while the “F” indicates that the cable is suitable for use in continuous operation at a maximum conductor temperature of +85°C.

What is the structure of H07RN-F cable?

The cable structure of H07RN-F typically consists of a stranded copper conductor, an ethylene propylene rubber (EPR) insulation, and a polychloroprene (PCP) outer sheath. The stranded copper conductor provides flexibility, while the EPR insulation provides resistance to high temperatures and electrical conductivity. The PCP outer sheath provides protection against abrasion, moisture, and chemicals.

What is the specification of H07RN-F cable ?

The specification of H07RN-F cable varies depending on the application and the manufacturer. However, some common specifications for H07RN-F cable include:

• Voltage rating: 450/750 volts
• Temperature rating: -25°C to +85°C
• Conductor size: 1.5mm² to 630mm²
• Core colors: black, brown, blue, grey, green/yellow
• Standards: BS EN 50525-2-21, VDE 0282, HD22.4 S4, IEC 60245-4

What is the difference between H05RR-F and H07RN-F?

H05RR-F and H07RN-F are both types of flexible rubber cables, but there are several differences between them.

1. Voltage rating: H05RR-F is rated for a lower voltage than H07RN-F. H05RR-F has a voltage rating of 300/500V, while H07RN-F has a voltage rating of 450/750V.
2. Temperature rating: H07RN-F has a higher temperature rating than H05RR-F. H07RN-F is rated for continuous operation at a maximum conductor temperature of +85°C, while H05RR-F is rated for a maximum conductor temperature of +60°C.
3. Outer sheath material: H07RN-F has a polychloroprene (PCP) outer sheath, while H05RR-F has a polychloroprene/Neoprene (PCP/Neoprene) outer sheath.
4. Conductor size: H07RN-F is available in larger conductor sizes than H05RR-F. H07RN-F is available in conductor sizes from 1.5mm² to 630mm², while H05RR-F is available in conductor sizes from 0.5mm² to 6mm².
5. Flexibility: H05RR-F is more flexible than H07RN-F. H05RR-F is designed for light duty applications and has a higher degree of flexibility than H07RN-F, which is designed for heavy duty applications.

In summary, H07RN-F is designed for heavy duty applications that require a higher voltage rating, higher temperature rating, and larger conductor sizes. H05RR-F is designed for light duty applications that require a higher degree of flexibility and a lower voltage rating.

What Applications is H07RN-F used for ?

H07RN-F cable is commonly used in industrial and construction applications, such as mining equipment, power tools, portable machinery, and lighting. It is also used in outdoor events, such as festivals and concerts, where the cable needs to be flexible and resistant to harsh weather conditions.
