Vibration dampers, type ГВУ
The uniform vibration dampers, type ГВУ are intended for vibration protection of bare conductors and ground wires for OTL and self-supporting fiber optic cables.
Legend to the marking of vibration dampers, type ГВУ-P1-m1-m2-d-L-М1:
Г – damper;
В – vibrations;
У – wire dancing;
П1 –availability of a protective element;
m1 and m2 – weights, m1 ≠ m2, kg;
d – diameter of a damper rope, mm;
L – length of the damper rope, mm;
M1 – retainer modification:
1 – coupling diameter 9 to 18 mm;
2 – coupling diameter 18 to 29 mm;
3 – coupling diameter 28 to 38 mm;
ATTENTION: The standard delivery set for vibration damper, type ГВУ does not include protective element which shall be ordered separately.
Vibration dampers, type ГВУ meet the requirements of TU U 31.2-30255335-002:2006.
