The laboratory has completed the tests for more than 300 tower-poles of domestic transmission lines and more than 40 tower-poles of foreign countries, which offers a reliable technical basis for optimized design of the tower-pole structures. The station carried out theoretic and test study on structural design and construction design for the first 330kV, 500kV and 750kV transmission projects in China.

    Transmission Conductor Mechanical Property Laboratory

The laboratory is dealt with test and study on the aeolian vibration of overhead conductor and ground wire, conductor and ground wire fatigue, conductor creep, power characteristic of dampers and appraisal of vibration-proof result, mechanical and electrical properties of spacers, field vibration measurement of large crossing, conductor anti-galloping of overhead lines, optimum configuration of spacers for bundle conductors, conventional mechanical and electrical properties of overhead conductor and ground wire and hardware, etc. The laboratory has completed the tests of vibration-proof for more than ten projects of large crossing, including Yangtze River crossings at Nanjing Dashengguan, at Wuhu for Long-Zheng line, tests on mechanical properties for conductor and ground wire with hardware of transmission lines at different voltages in China. The laboratory has offered forceful technical assistance and guarantee for construction of transmission lines in China.

    EHV Power Cable Laboratory

The laboratory consists of completed set of test equipment, shield hall and pre-qualification test outdoor yard for EHV cable. Internal size(L*W*H) of the shield hall is 40m*30m*20m and the test yard covers 80m*40m. The shield hall can well meet the requirement of 500kV power cable PD test. In the shield hall, there are three resonant test systems of 800kV/30A, 800kV/6A and 800kV/4A, two sets of de-ion water cable test terminator of 800kV & 350kV and their water conditioner; 600kV standard capacitor; partial discharge (PD) detector, etc. In addition, several power cable conductor inducing heating system and automatic control & measurement system have been developed. An impulse generator of 2800kV is to install. The test ability and scale of this lab reaches to the first degree in the world. The laboratory can carry out the following research work, such as the research on cable installation technique, operation behavior and detective technique; type test; prequalification test and acceptance test for power cable & accessories. The laboratory has been done the research work for Ertan 500 kV cable imported from France, the test work for Three Gorge left bank 500kV GIS equipment.
