PHASE-TO-PHASE INSULATING SPACER FOR OVERHEAD TRANSMISSION LINES Russian patent published in 2024 - IPC H02G7/12 

FIELD: electric power industry.

SUBSTANCE: invention relates to the field of electric power engineering, in particular to interphase insulating spacers. Spacer comprises insulating part (3), on one side is connected with attachment points (1) to wires (2), and on the other side is connected to flexible element – cable (6) – by means of clamps (7) and (8). To ensure the possibility of adjusting the interphase distance, the spacer is equipped with a means for adjusting its length in the form of a brace formed by clamps (7) and (8), wherein clamp (7) is made to be pressed rigidly fixing cable (6) at one end while second clamp (8) arranged at the other end of cable (6) is adjustable to allow changing and locking the cable working length. Insulating parts (3) are connected to brace by at least one pair of brackets of SK type (9), which form hinged chain connection made with possibility of rotation in two planes.

EFFECT: provision of possibility to adjust interphase distance of spacer, increase of operation reliability and increase of its service life.
