The cable is applied for connecting of mobile usersat points where medium mechanical strains occur and in dry rooms where there is no danger of explosion and in mines without methane. At application tensile strain of short duration should not exceed 10 N/mm2 of total conductor cross-section. Bending radius must not be below:
- 4D for normal usage
- 10D for tugging over wheels (guides)
- 10D for winding on wheels (reels)
