A cable fault locator was designed to detect and analyze the faults of grounding,mixed line,to solve the problem of cable line routing and to locate the faults,which occur in all kinds of power supply bus lines in electric power,railway and various industry and mining enterprises.

With this instrument the frequency characteristics of the cable line can be fastly detected, and the nature of the broken, short circuit faults and the mixed line faults of cables as well as the fault locations can be judged and located.

Predictive study on the color of naturally colored cotton/cotton blended yarn;

Flexibility test and analysis of pure bamboo pulp yarns and blended yarns;

Flexibility of pure bamboo yarns and bamboo blended yarns;

Study on the pilot scale experiments of the treatment of micro-polluted raw water using in-line coagulation;

To find a practical and feasible solution, existing fault location methods are induced and summarized according to the specialty of distribution networks different from high voltage transmission lines, such as hybrid lines in which overhead lines and power cables coexist, highly branched lines, short line length, etc.

The key technologies of carrier communication using non-intrusive coupling devices for hybrid lines,which consist of overhead lines and underground cables,are studied,and reliability and economy of the key technologies are verified through site tests.
