一种可延长双拼接电缆中间接头的研究与应用

Research and Application of A Prolonged Double Spliced Cable Intermediate Joint

在10kV配电网系统中,特别是市政电缆沟不完善的地区,直埋敷设是一种常用的敷设方式。直埋电缆受运行时间、线路环境等影响,电缆很难拖动。当电缆中间接头或者电缆本体故障时,需要切除损伤的电缆,导致现场原有电缆长度不够,无法通过安装一个电缆中间接头来完成修复,为克服电缆中间接头的技术不足,提出了一种可延长双拼接电缆中间接头,能够短时间、低成本解决故障电缆的连接问题,具有一定的实用性和经济性。

In the lOkV distribution network system？ especially in the municipal area that cable trench is not perfect, bur-ied laying is a commonly used laying way. Buried cable by the operation time,line environment and other effects？ the cable is difficult to drag. If the cable intermediate connector or cable body failure, it is needed to remove the damaged cable. However, because the original cable is not long enough, it is unable to be repaired by installing a cable interme-diate connector. An extendable double splicing cable intermediate connector is proposed, which can solve the problem of connecting the fault cable quickly with low cost.
