FIELD: manufacturing technology.
SUBSTANCE: present invention relates to device (1) for expansion of multi-strand wire strand (301) of tensioning cable, in particular, steel wire strands of tension rope, wherein device (1) comprises main body (3) with hole (7) for conducting the entire wire strand of tensioning cable, as well as several spacer elements (5a-5c, 9a-9c), which are installed in main body (3) movably in radial direction, and each of them has a contour converging in radial direction for insertion between the adjacent strands of wire strand tension cable and creation of gap (13) between these respectively adjacent conductors. Invention also relates to the use of said device (1) and the expansion method, as well as lubricating device (100) with such expansion device (1).
EFFECT: this device (1) simplifies the expansion operation.
