DEVICE FOR FIXING INSULATED WIRES ON SUPPORTS OF AIR TRANSMISSION LINES (OPTIONS) Russian patent published in 2018 - IPC H02G7/05 

FIELD: electric power engineering.

SUBSTANCE: invention relates to the electric power industry, namely to devices for fixing insulated wires on the supports of overhead power lines. Device (its variants) comprises a clamp, a shunt connected to the clamp and a contact clamp piercing the insulation of the wire conductor. In case of the anchoring variant of fastening (Fig. 1) the spiral clamp consists of U-shaped power spiral 1, loop 2, and cushion 3. Power spiral 1 of loops 2 is inserted into cushion 3 and its ends are wound on wire 4. Shunt is made from insulated or uninsulated conductor 5, fixed at one end by girdle 3, and fixed at the other end into contact terminal 6.

EFFECT: invention allows to achieve a significant result in terms of ensuring reliable operation during use and saving material costs during their manufacture and installation.
