接续金具主要用于架空电力线路的导线、避雷线的接续和补修。按结构形式和安装方法的不同，分为压缩型、螺栓型和预绞 丝各三类：压缩型又分为液压、
爆压和钳压三种。
各种接续金具直流电阻不大于等长导线直流电阻；载流温升低于导线的温升。压缩型接续管对导线的握力不小于导线计算拉断力的 95%。
产品型号中字母和数字的意义为： 接续金具
J- 接续 D- 搭接 X- 补修 B- 爆压、并沟、补修、避雷线 T- 椭圆、跳线
M- 母线 Y- 圆形、预绞丝 S- 伸缩、设备
数字表示适用导线的大小：
Splices are used for splicing or repairing conductor and ground wire of overhead transmission lies.The splices may be compression type，bolt type
performed armour rods in accordance with the construction and mounting way.The compressive splices have hydraulic.explosive and notched type.
The DC resistance of all splices must be less than that of the equi-length conductor，the temperature rise of all splices must be less than that of the
splicing conductor.The slip strength of the compressive sleeve must be not less than 95% of the rated strength of conductor.
The meanings of letters Arabic figures in the catalog are shown as follow:
J-splice D-overlap joing X-repair B-explosion，parallel，repair or ground wire.
T-oval，jumper M-bus-bar Y-round，preformed S-flexibility equipment.
The arabic figures show sizes of conductor
