H07RN-F heavy duty rubber flex, single/multicore

H07RN-F heavy duty rubber flexible rubber cables are available in single or multicore formats. They are designed for trailing or mobile power supply applications. Commonly used in generators, portable equipment, moving machinery handling equipment etc. 

The tough rubber sheath renders this cable type suitable for indoor or outdoor applications including in wet and oily  areas. For example on worksites, external stages, port areas and in severe industrial environments.

These H07RN-F heavy duty rubber cables are also refered to as HO7RN-F, H07RNF & HO7RNF. 

PCP or Neoprene Rubber (Polychloroprene) Properties: this self-extinguishing compound has excellent resistance to oxygen, UV, ozone & water and very good resistance to acids, alkalis & solvents. It also has good abrasion resistance.
