DAMPING DISTANCE PIECE FOR WIRES OF AIR TRANSMISSION LINES Russian patent published in 2018 - IPC H02G7/14 

FIELD: electric power engineering.

SUBSTANCE: invention relates to power industry, namely to the damping distance spacers for the phase conductors, split into two or more components of overhead transmission lines of different voltage classes. Above spacer consists of body 1 made of an aluminum alloy representing a bulk frame, formed by vertical and horizontal ribs 2, 3. Cups 4 are integrated into frame 1, depending on the number of wires 5 in the split phase. In cups 4, damping nodes are placed, consisting of rubber damping elements 6 of the toroidal form. Damping elements 6 are connected by two dies 7 to each damping unit by means of special fastening elements. Set of special fasteners includes bolts 8 with fine thread, washers 9 and all-metal self-locking nuts 10. On slots 7, notches 11 are made, which extend at an angle with respect to longitudinal axis 12 of wire 5.

EFFECT: invention provides a spacer with high vibration characteristics, providing effective damping of oscillations from low to high frequencies, and acceptable reliability during long-term operation.
