摘　　要：介绍了一起110 kV电缆终端构架撑杆螺栓发热缺陷。通过对电缆设备进行检查分析,确认接地扁铁与接地网接触不良以及中间接头处护层接线连接错误是导致发热的主要原因,并针对这一情况制定了相应的处理对策,为今后类似问题的解决提供参考。A fault of overheat of a bolt of the strut at an 110 kV cable termination is introduced. A check and analysis of the cable machinery are implemented and it is found that bad contact between grounding fiat iron and grounding grid and connection error in the induced sheath are the main causes of the overheat. Corresponding countermeasures for tackling this kind of fault are designed, which provides a reference for similar issues in the future.
