European directives: 2014/35/UE (LVD)  - 2011/65/EC and 2015/863/EU (RoHS).

Conductor: flexible annealed plain copper class 5 (EN IEC 60228).

Insulation: Rubber of type EI4.

Core colours:
Two-core : blue-brown;
Three-core : green/yellow-blue-brown or brown-black-grey;
Four-core : green/yellow-brown-black-grey or blue-brown-black-grey;
Five-core : green/yellow-blue-brown-black-grey or blue-brown-black-grey-black.

Sheath: Rubber of type EM2.
Colour black; if specifically requested, and for agreed quantities, the sheath can be supplied in other single-colours.

Marking: continuous marking on the sheath « LOMBARDA H07RN-F nominal cross section OZONE RESISTANT  IEMMEQU <HAR> production date Made in Italy  Eca».

Minimum installation and handling temperature: - 25 °C

Maximum operating temperature: 85 °C on the conductor if in a protective installations.

Minimum usage temperature:- 40 °C only if the cable is not subjected to shocks, vibrations, movements or other mechanical stresses. If the cable is operated at a constant current and so is not subjected to expansions and contractions due to the conductor temperature variations, it is possible to be used even at lower temperatures.

Maximum short circuit temperature: 200 °C on the conductor (for maximum 5 seconds).

Minimum internal bending radius:
For free movement: 4 times the greatest overall dimension if less than 12 mm; 5 times if between 8 and 12 mm; 6 times if greater than 12 mm;
For fixed installations: 3 times the greatest overall dimension if less than 12 mm; 4 times if greater than 12 mm;
For repeated reeling: 6 times the greatest overall dimension if less than 20 mm; 8 times if greater than 12 mm.

Maximum tensile stress: 1,5 kg/mm² of the conductor cross section.

Current carrying capacity: see EN 50565-1 standard and CEI-UNEL 35024. For cross-sections up to 1 mm² current 10 A

Guide to Use:
for use in dry or moist rooms, in open air; for medium mechanical stresses, e.g. for industrial and agricultural workshop appliances, large boiler rooms, heating plates, inspection lamps, electrical tools such as drills, circular saws, domestic electric tools; also for mobile motors or machines on building sites or in agricultural working, etc; also for fixed installations, e.g. on rough-cast in temporary buildings and huts used for accommodation purposes; suitable for the wiring of construction components in lifting appliances, machinery, etc.
Use up to 1.000 V, a.c. is permitted for fixed, protected installations (in conduit or appliances), and also for motor connections of hoisting motors and like.
Installation directly or indirectly buried or immersed in water is not allowed.

Further instructions and guidance for use are given in the EN 50525-2 standard.

All the above cables are to be used only for electrical power transmission and to be installed only by skilled personal.

The cables H07RN-F are "flame retardant on a single vertical cable test" according to the test EN / IEC 60332-1-2 as indicated in the EN 50525-2-21 and EN 50525-2-81 standards.

The cables contained in this brochure do not need the RoHS conformity declaration as they fall out of the scope of the directive. These cables may been used with electric/electronic equipment that  are called up by the directive as they satisfy the RoHS requirements.
