The power transmission line of 220KV and 330KV uses binary fission conducting wire, 500KV power transmission lines that tripartition and conductors on quad bundled, voltage is used to be higher than
The ultra high-tension transmission line of 500KV is using six divisions and more polytomic conducting wire, in order to ensure that split conductor harness spacing is kept not
Become to meet electric property, reduces surface voltage gradient, and in a short-circuit situation, electromagnetic force is will not occur between wire harness, make
At the collision that attracts each other, though or cause the attraction of moment collide, normal condition can be restored to after accident elimination, thus in shelves
It is separated by a distance away to be mounted with that conductor spacer, installation interval stick also play the oscillation and aeolian vibration of secondary span certain
Inhibiting effect can substantially be divided into two classes, i.e. damping spacer and non-damping spacer by the working characteristics of conductor spacer, damping
Type conductor spacer feature is:The vibrational energy for consuming conducting wire as damping material using rubber at conductor spacer turning joint, to leading
Linearly coupled generates damping action, and therefore, such conductor spacer is suitable for each department, still, it is contemplated that the economy of power transmission sequence, it should
Class conductor spacer emphasis is the circuit in the area that vibration is easy tod produce for conducting wire, and the absorb shock resistance of non-damping conductor spacer is poor, can fit
For being not likely to produce the regional circuit of vibration or being used as jumper wire spacing rod.
In the prior art, especially double bundle conductor easily occurs when encountering the oscillation and aeolian vibration of time span
Resonance so that two conducting wires generally require to consume energy by shaking for a long time and could stop vibrating.
