對于單相的直埋敷設,不能用鐵磁材料作保護盒,建議用玻璃鋼或硬質塑料保護盒。 與傳統的電纜附件施工工藝不同,預制式電纜附件施工工藝復雜,工技術難度較大,它的安裝程序和工藝要求不容易被施工人員熟練握,施工中普遍存在這樣或那樣的問題,是影響電纜分支箱正確安裝與安全運行的主要因素。
For single-phase direct buried laying, ferromagnetic materials cannot be used as protective boxes, and FRP or hard plastic protective boxes are recommended. Different from the traditional construction process of cable accessories, the construction process of prefabricated cable accessories is complex and difficult in engineering and technology. Its installation procedures and process requirements are not easy to be mastered by the construction personnel. One or another problems generally exist in the construction, which are the main factors affecting the correct installation and safe operation of cable branch boxes.
電纜在安裝的時候需要通過各種技術手段來確定電纜附件長度,對復檢長短合適、平齊,防止因過長或過短相電纜產生較大的推力或拉力,導致固定的T型電纜接頭與電纜或電纜分接箱出線套管接觸不良,避免電纜分接箱出線套管因受力導致漏氣。
During cable installation, the length of cable accessories shall be determined through various technical means, and the recheck length shall be appropriate and flush to prevent large thrust or tension caused by too long or too short phase cables, resulting in poor contact between the fixed T-shaped cable joint and the cable or the outlet sleeve of the cable junction box, so as to avoid air leakage caused by stress on the outlet sleeve of the cable junction box.
電纜分接箱基礎內必須安裝電纜固定支架,電纜三心分相處以下在支架上進行固定處理,同時應采取措施保證三叉頭在接線柱的正下方,確保不發生分接箱內電纜及附件受到下拉力,這樣可以有效避免電纜分接箱出線套管因受力導致漏氣現象的發生。
The cable fixing bracket must be installed in the foundation of the cable distribution box, and the cable with three centers shall be fixed on the bracket. At the same time, measures shall be taken to ensure that the Trident head is directly below the terminal to ensure that the cable and accessories in the distribution box are not subject to downward tension, so as to effectively avoid air leakage caused by stress on the outlet sleeve of the cable distribution box.
