四種類型的滑觸線的性能特點：
The performance characteristics of four types of sliding contact line:
1、單極滑觸線：根據不同的極數進行組合，電流也可達千安，是目前zui常用的滑觸線。
1, unipolar sliding contact line: according to the number of different combinations, current also can amount to thousands of Ann, sliding contact line is by far the most commonly used.
2、多極滑觸線：它的安裝方便，速度快，結構簡單緊湊，安全可靠，適用于電流在100A以下常用。
2, multipolar sliding contact line, its installation is convenient, fast, simple and compact structure, safe and reliable, applicable to the current commonly used below the 100 a.
3、安全滑觸線：安全滑觸線可以用于灰塵、潮濕等環境，可配防塵密封條和手保護。集電器運行速度小
3, safety sliding contact line: safety sliding contact line can be used in the environment such as dust, moisture, dust can match sealing strip and hand protection. The running speed small collector
于300米/分鐘。
In the 300 m/min.
4、剛體滑觸線：剛體滑觸線一般用于高電流設備，電流可達幾千安，適應于環境惡劣，溫度高。
4, rigid body sliding contact line: rigid body sliding contact line is generally used in high current equipment, electric current can amount to thousands of Ann, adapted to the conditions of high temperature.
