T 形线夹

T-connectors

T 形线夹主要用于架空电力线路或变电所，在母线以 "T" 形方式引下电流分支。分螺栓型和压缩型两类，对于小截面导线也可用并沟线夹或钳压椭圆接续管
作为 T 型连接。
产品型号中字母和数字的意义为：T-T 接 Y- 压缩 L- 螺栓；数字表示适用导线标称截面积。
T 形线夹对导线的握力不小于导线计算拉断力的 10%，但螺栓型线夹适用导线直径大于 49mm 时，不小于 3%。线夹的直流电阻不大于等长导线的直流电阻。
载流温升低于导线的温升。
使用电压在 330 kV 及以上的 T 型线夹，在 1.05 倍最高运行电压下无可见电晕。
T-connectors are used to connect tap conductor with bus line the way of tee joint on overhead transmission lines or substations. The connectors include
bolt type and compression type Actually, parallel groove clamp also can be used as T-connectors for conductor of small size.
The meaning of letters & Arabic figures in the catalog are shown as follow: T-tee connection M-bus-bar Y-compression G-Tube L-bolt
The arabie figures show conductor size.
The slip strength of the connector should be not less than 10% rate ultimate strength of the conductor, except that of bolt type connector used for
conductor diameter equaling or larger than 49mm, for this case, a slip strength of 3% ultimate strength is allowed D.C resistance of the connector should
be less than that of equi-length conductor the temperature rise of connector should be less than that of the conductor. No visible corona for system
voltage up to 330 KV or higher, test voltage should be 1.05 of max, operating voltage.
