HO5RR-F and HO7RN-F are two common rubber cable models on the market, but many users find it difficult to distinguish between them. In fact, although they both belong to the rubber cable series, they differ significantly in terms of voltage resistance, temperature resistance, oil resistance, and protection rating.
HO5RR-F is a light-duty rubber cable with a rated voltage of 300/500V, suitable for lightly loaded household appliances, small tools, etc., and can be used indoors or in light outdoor environments. HO7RN-F, on the other hand, is a heavy-duty rubber cable with a rated voltage of 450/750V and excellent oil resistance, abrasion resistance, and water resistance. It is commonly used in high-intensity applications such as construction sites, welding machines, motor equipment, and industrial settings.
In terms of flexibility, both perform well, but HO7RN-F, due to its neoprene or EPDM rubber sheath, has stronger weather resistance and is more suitable for long-term outdoor use.
Therefore, your choice should be based on the power of the equipment and the operating environment:
Household or light-duty equipment → HO5RR-F
Industrial, outdoor, high-load equipment → HO7RN-F
Choosing the right model not only extends cable life but is also crucial for the safe operation of your equipment.
