H07rn-F Heavy Rubber Sheathed and Rubber Insulated Flexible Cable

Application

Used for medium and heavy mechanical loads, in dry and wet areas, also outdoor. Could be installed under or on plaster, in rocks, concrete, but not in pre-stressed concrete. Cable suitable for fixed industrial and home installation, for operating conditions with possible fire or explosion hazard, for mobile energy users, machine tools and agricultural machines, for construction sites at medium mechanical loads, for large kettles, heating plates, hand lamps, electrical tools such as drills, circular saws and electrical tools for household use, same as for mobile engines or machines on construction sites and craftsman i.e. agricultural plants. Permitted fixed laying on crane and machine elements etc. Permitted voltages up to 1000 V AC at protected laying in tubes or devices, and as connecting rotor cable for engines. Also suitable for cooling installations. Resistant to oil, ozone and UV irradiation.
