電纜線路接地部位的確定

發布日期：2022-04-18 點擊率：66

電纜線路的接地部位應根據不同的環境、不同的電纜類型等因素來確定：

    (1)電纜類型方面。不同的電纜類型其接地方式如下：

    1)單芯電纜。其截面積大于等于16mm2時，為了消除渦流，它的金屬外表面的一端應接地。

    2)平行敷設兩根單芯電纜。為防止產生較高的感應電壓，要采用多點接地方式。

    3)非金屬外皮電纜。對這類電纜的支架必須接地。金屬外皮電纜的支架可不接地。

    (2)環境方面。高壓電纜兩端均應接地，地下室的電纜兩端也應接地，對于有導電粉塵或腐蝕性氣體等危險的場所的電纜，其兩端也應可靠接地。
