H07RN8-F Multi core EI4 rubber insulated EM2 rubber sheath cable
Application：
H07RN-8-F can be constantly immersed in fresh water to a depth of up to 10 meters at a water temperature of +40oC. This makes it suitable as an energy supply cable for submersed pumps. However, it is not suitable for underwater power transmission, or installation in a waterway, or where it is possible that mechanical damage might occur and cause hazard. It is commonly used as a floater switch to connect equipment in industrial water and in flexible applications in swimming pools.

n the world of electrical installations, Choosing the right cable is crucial to ensuring safety, the efficiency and durability of the installation. Today, we will introduce you to two popular cables – the H07RN8-F and the H05VV-F – which stand out for their technical specifications and applications. Thanks to this detailed comparison, you will know which cable to choose for your specific needs.
H07RN-F and H07RN8-F cables may seem quite similar, but H07RN-F cables are better suited for flexible applications due to their higher flexibility, whereas H07RN8-F cables are designed to withstand the pulling forces from equipment.
Maximum conductor temperature is typically 60°C when submerged in water, and up to 85°C to 90°C for fixed installations in dry environments.
It is most commonly used as a power and control connection cable for submersible pumps, water treatment equipment, and various mobile industrial or agricultural underwater appliances.
