Description

Insulator string anti-wind deviation device for single hanging point of transmission line

technical field

The utility model relates to an anti-wind deviation device for an insulator string on a transmission line, in particular to an anti-wind deviation device on a 220 kV transmission line.

Background technique

Some existing transmission lines do not meet the wind deflection requirements and need to be modified. In particular, some existing 220 kV transmission lines are modified to meet the wind deflection requirements by using standard hangers and supporting hardware weights. However, for the insulator strings with single hanging points of straight towers that do not meet the requirements of wind deflection, it is impossible to add a heavy hammer to the original hanger. Windproof requirements.
