供電安全單極滑觸線裝置由導管，單極滑觸線導電器兩主要部件及一些輔助組件構成如圖：
The power supply safety of the single pole sliding contact line is made of a catheter, a single pole sliding contact line guide apparatus two main parts and some auxiliary components:
1、滑觸線導管：是一根半封閉的異形管狀部件，是安全滑觸線的主體部分。其內部可根據需要嵌設2-9根裸體導軌作為供電導線，各導軌間相互絕緣，并與外殼絕緣，從而保證供電的安全性。
1, sliding contact line pipe: is a semi closed shaped tubular parts, is the main part of the safety of sliding contact line. Its internal can be set according to the need to set the 2-9 root naked guide as a power supply wire, each guide rail insulation between each other, and with the shell insulation, thereby ensuring the safety of power supply.
并在帶電檢修時有效地防止檢修人員觸電事故。重慶天寶生產的導管每條長度6m，可以連接成任意需要長度，普遍導管制作成直線形，也可以按特殊需求制成圓弧形等。
And in the electric maintenance to effectively prevent the maintenance personnel electric shock accident. Production of Chongqing Tianbao catheter each 6m length can be connected to any desired length, universal catheter into straight, can also be made according to the special needs of circular arc.
2、滑觸線導電器是在導管內運行的一組電刷殼架，滑觸線由安置在用電機構（行車、小車、電動葫蘆等）上的拔叉（或牽引鏈條等）帶動，使之與用電機構成同步運行，將通過導軌，滑觸線電刷的電能傳輸到電動機或其它控制元件。導電器電刷的極數有3-16極與導管中導軌數相應。
2, sliding contact wire guide is a set of electric brush frame, sliding contact line from the placement in the electric machine (driving, car, electric hoist, etc.) on the pull fork (or traction chain, etc.), so as to make the synchronous operation with the motor, the electric brush through the guide, the electric brush can be transferred to the motor or other control components. The pole number of the electrical conductivity of the electric appliance is 3-16 pole and the number of guide rail in the guide.
