stagger wire

It proposes to adopt variable stagger arrangement and to change the horizontal tension link on push-off device into the compression link so as to reduce the deflection of contact wire in area adjacent to mid-point anchor in straight line and in large span length up to 65 m.

提出在直线区段的中心锚结附近和65m大跨距内，采取不等之字值布置法和反定位装置处的水平拉杆改成压管的措施减小接触线风偏。

And the extension amount, extraction amount and tangent line stagger of the contact wire in the whole tensioning section can be obtained by calculation, and then the total reservation length of contact wire before cutting can be obtained thereof.

通过计算，求出整个锚段内接触线的延伸量、收缩量和直线拉出值，从而得出断线时接触线总预留长度。
