一、產品質量問題
A, product quality problems
      安全滑觸線軌道發生彎曲很大部分原因是因為產品質量不合格，提掛架、導體外殼等雜質含量高，機械強度不能達到要求，很容易導致導軌發生變形，很多滑觸線生產廠家為降低成本，會在導體內部摻 入很多雜質，這樣產品在使用過程中局部溫升過高，也容易引起滑觸線發生彎曲。
Safety sliding contact line rail bending part of the reason is because of the unqualified product provided, conductor shell, rack high impurity content, mechanical strength can not meet the requirements, it is easy to cause the rail deformation, a lot of sliding contact line manufacturers to reduce costs, will be inside the conductor mixed with a lot of impurities, such products in use the local temperature is too high, also easy to cause the sliding contact wire bending.
二、提掛架間距過大
Two, the pylon spacing is too large
    輕型滑觸線提掛架間距為1.2米/個，重型滑觸線間距為2.4米/個，如果客戶有特殊要求可以根據客戶需求進行配置，如為降低成本增加提掛架間距，則不能夠有足夠強度支撐滑觸 線，所以很容易出現彎曲下垂等現象。
Light sliding contact line extraction pylon spacing is 1.2 meters /, heavy sliding contact line spacing is 2.4 meters /, if customers have special requirements can be configured according to the customer demand, such as to reduce cost and increase lift pylon spacing, are not able to have sufficient strength to support the sliding contact line, so very easy to appear droop etc. phenomenon.
