接續(xù)金具 Splicing Fitting
接續(xù)金具主要用于架空電力線路的導線、避雷線的接續(xù)和補修。按結構形式和安裝方法的不同，分為壓縮型、分為壓縮型、螺栓型和預型和預絞絲各三類：壓縮型又分為液位、爆壓和鉗壓三種。
產(chǎn)品型號字母和數(shù)字的意義為：
J-接續(xù) D-搭接 X-補修 B-爆壓、并溝、補修、避雷線 T-橢圓、跳線
M-母線 Y-圓型、預絞絲 S-伸縮、設備
數(shù)字表示適用導線的大?。?
各種接續(xù)金具直流電阻大小等長導線直流電阻；載流溫升低于導線的溫升。壓縮型接續(xù)管對導線的握力不小于導線計算接斷力的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.
