Splices are used for splicing or repairing conductor and ground wire of overhead transmission lines. The splices may be compression type, bolt type performed armor 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 equal 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 joint 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.
