In order to improve the current situation and ensure the safe and stable operation of the transmission line, in combination with the defects in recent years, deep analysis and discussion are carried out, and the conditions that the single wire provided with the wire clamp type galloping-prevention spacing rod is not subjected to strand breaking and wire breaking at the wire clamp position and the conditions that the galloping-prevention spacing rod provided with the double split wires is subjected to strand breaking and wire breaking for multiple times are found, so that the fact that the true 'original fierce' of the wire breakage and wire breaking is a fixed type vertical double-row suspension wire clamp can be judged. As shown in fig. 1, the connection between the upper and lower sub-conductors (typically 400mm apart) in the prior art devices is fixed and can easily cause damage due to high stress on the conductors caused by the waving between the upper and lower sub-conductors. If the fixed connection mode of the vertical double-row suspension clamp is changed into the flexible connection mode, certain movement margin exists among the sub-conductor suspension clamps, vibration energy in the clamps can be effectively reduced, the risk of strand breakage and wire breakage of the conductors is reduced, and the power supply reliability is improved.
