AI Technical Summary

Technical Problem

Existing power cable cold resistance testing devices cannot fully consider the simultaneous effects of tension and torsion that cables may encounter in actual use, resulting in inaccurate test results. They also occupy laboratory space and equipment resources, increasing testing costs and difficulty.

Method used

A device for testing the cold resistance of power cables was designed. It uses a bidirectional threaded rod and multiple sets of cable clamps to simultaneously test the tensile force and torsion of the cable at low temperatures. The tensile and torsional tests are achieved by rotating the turntable and driving the cable clamps with a motor.

Benefits of technology

It enables the testing of tensile and torsional forces on cables in low-temperature environments, saving laboratory space and equipment resources, reducing testing costs and steps, and simplifying the testing process.
