为了保证输电线路施工中耐张管压接角度的准确性，研制并使用了耐张线夹角度定位画线器和定位辅助器。介绍了定位画线器和定位辅助器的部件组成和工作原理。工程应用表明，研制的定位画线器和定位辅助器经济效益和社会效益良好。建议耐张管加工时增加角度线工序，以保证压接施工方便。

The locating scriber and auxiliary positioning device of crimping angle was developed and applied in order to ensure the accuracy of crimping angle of strained drainage tube in transmission line. This paper introduced the he components and the working principle of locating scriber and auxiliary positioning device. The results of engineering application show that the development of locating scriber and auxiliary positioning device can produce good economic and social benefits. This paper suggested that angle line procedure should be increased in the strained tube processing for the convenient construction.
