Description
[technical field]
The utility model relates to the technical field of overhead transmission line, particularly a kind of technical field of conductor spacer.
[background technology]
It is the large factor that transmission line safe and stable operation in serious threat that ice coated on overhead transmission line conductor is waved always.When wire icing is waved, each phase conductor there will be different wave, the random vibration of out of phase, very easily there is alternate or relatively air breakdown flashover, wave the serious accident that overlong time can cause transmission line hardware, lead wire and earth wire, shaft tower etc. to damage, wave and bring very large harm to the safe operation of transmission line.
Conductor spacer is one of anti-dancing device of control conductor galloping, and its anti-dance principle is that each phase conductor is mechanically coupled together, and makes it mutually pin down when moving, to reach the object suppressing to wave.Of the prior art, the oidiospore lead spacer of the structure of jumper wire spacing rod normally regular length, not only can affect the visual aesthetics of wire jumper, and stress can be caused to concentrate, easily destroy jumper wire spacing rod.
