接续金具 Splicing Fitting
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、分为压缩型、螺栓型和预型和预绞丝各三类：压缩型又分为液位、爆压和钳压三种。
产品型号字母和数字的意义为：
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-圆型、预绞丝 S-伸缩、设备
数字表示适用导线的大小：
各种接续金具直流电阻大小等长导线直流电阻；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接断力的95%。
Spelices are used for splicing or repairing of conductor and ground wire of overhead transmission lies.The splices may be compression type.bolt type performed armour rods in accordnce with the construction and mounting way.The compressive splices have hydraulic,explosive and notched type.
The meanings of letters Arabic figures in the catalog are shown as follow:
J-splice D-overlap joing X-repair B-explosion,paraller,repair or ground wire.
T-oval,jumper M-bus-bar Y-round,preformed S-filexibility equipment.
The arabic figures show size of conductor
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 splices conductor.The slip strenght of the compressive must be not less than 95% of the rated strength of conductor.
