H07RN-F

Design

The design of H07RN-F consists of one or more insulated copper stranded conductors of the 5th class of flexibility, with round shape. Each conductor is covered with a layer of thermoplastic elastomer. Insulated conductors are stranded together into a core by correct unidirectional twisting, which provides increased cable flexibility. In multi-conductors cables, the free space between the conductors is filled. The sheath is made of blue or black thermoplastic elastomer. In a single-conductor cable, the copper conductor is covered with the insulation and a sheath or immediately with an insulating-protective sheath also made of thermoplastic elastomer.

2-conductors cables have the same conductor cross-section. In the rest of the multi-conductor cables, the neutral conductor or the grounding conductor has a smaller cross-section compared to the phase ones. For the convenience of cutting, the conductors are treated with talcum powder, which reduces the labor intensity of the work.

Operation

H07RN-F are designed to connect mobile mechanisms to power grids at the ambient temperatures from -60°C to +50°C. Installation of the cable without preheating is allowed at a temperature not lower than -15°С.

H07RN-F is extremely flexible, the minimum bend radius is at least 8 cable diameters at an admissible heating temperature of the conductors of up to +75°С.

Tensile forces on the cable should be no more than 19.6 N (2.0 kgf) per 1 mm² of the total cross-section of all conductors.

H07RN-F with a nominal cross-section of the main conductors up to 4 mm² inclusive and the number of conductors from 2 to 5 inclusive must be resistant to multiple bends through a system of rollers under a current load and withstand at least 30,000 bending cycles.

The cables with a nominal cross-section of the main conductors up to 4 mm² inclusive (single-conductor and with more than 5 conductors) and cables with a nominal cross-section of the main conductors of 6.0 mm² and more must be resistant to multiple bends at an angle of ± π/2 rad at a nominal tensile force of 49 H (5.0 kgf).

The service life of cables is not less than 4 years. The guaranteed service life of operation is 6 months, calculated from the date of putting the cables into operation, but not later than 12 months from the date of manufacture.
