Prysmian FLEXTREME MAX H07RN-F combines this flexibility with resistance to water, oil, UV and ozone, as well as impact resistance and suitability for demanding mechanical loads. It is HAR-certified, CPR-rated Eca and AD8 rated for permanent immersion in water up to 100 metres (10 bar). FLEXTREME MAX H07RN-F is a premium H07RN F flexible rubber cable variant for harsh environments, and as an H07RN-F cable it is specified where reliability is critical.

What is H07RN-F cable?

H07RN-F is a heavy-duty, rubber-insulated and rubber-sheathed flexible power cable.

It is designed for applications where cables may be subjected to movement, mechanical stress, moisture or challenging environmental conditions. Its flexible construction makes H07RN-F particularly suited to equipment and installations where flexibility and durability are required. In short, H07RN-F cable is used whenever a tough, mobile power solution is needed. Typical examples include portable tools, site power and industrial machinery that benefit from an H07RN F flexible rubber cable.

Prysmian FLEXTREME MAX H07RN-F has a rated voltage of 450/750 V, with permitted voltages up to 1 kV AC in the applications specified by the product datasheet.  

What does the marking H07RN-F mean?

The marking identifies key design parameters: H = harmonised (HAR) standard cable; 07 = 450/750 V rating; R = rubber insulation; N = polychloroprene or equivalent rubber outer sheath; F = fine-stranded flexible conductor. Together, H07RN-F denotes a harmonised, flexible rubber cable for 450/750 V service. This is why H07RN F flexible rubber cable is widely specified across Europe and trusted as a versatile H07RN-F cable for tough duties.
