船用電纜的填充及屏蔽層介紹

摘要:
    船用電纜用于在船舶電網中連接各種電氣設備,以傳輸電能或電氣信號。隨著船舶電氣化和自動化程度的不斷提高,船用電纜的品種和用量不斷增多。船用電纜基本上分為電力電纜、通信電纜及特種高頻電纜三大類,其中電力電纜用于電力、照明等系統,是船上使用多的電纜。

電纜的填充及屏蔽層:

    多芯電纜線芯間的縫隙必須使用物質(如非吸濕性材料)進行填充,填充時既可使填充物與護套分離開,也可以將填充物與護套擠壓為一體,還可將非吸濕性扎帶繞包在線芯與護套之間。另外,電纜內部還設有屏蔽層,目的是優化電纜內部的電場分布。電纜導體通常是多根導線絞合而成,其與絕緣層之間必定有縫隙,局部的電場會集中,在導體與絕緣層間設置內屏蔽層,可有效解決這一問題并防止線芯與絕緣層之間發生局部放電。而絕緣層與護套間設置外屏蔽層,可使護套與屏蔽層之間的電位相等,且絕緣層與屏蔽層間的接觸良好,避免局部放電的產生。.
