T型线夹主要用于架空电力线路或变电所，在母线的干线上以"T"型方式引下电流分支。分螺栓型和缩型两类，对于小截面导线也可用并沟线夹或钳压椭圆执着线管作为T型连接。

产品型号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型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，截流温升低于导线的温升.

使用电压在330KV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-connector 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-connector 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

T-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 equal or large than 49mm,for that.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.No visible corona for system voltage up to 330 KV or higher,test voltage should be 1.05 of max.operating voltage.
