Research On ACCC Conductor Comprehensive Performance

In recent years China's electric power systems developed rapidly, the phenomenon of transmission capacity of overhead conductors is serious deficiencies, the power company of all the countries are actively looking for the response programs. The best choice of programs is to find a suitable expansion of wire, preferably without changing the transmission corridor. ACCC is the best choice for this. However, the test and inspection for ACCC hanging on to run are not systems.To establish a test platform for test a ACCC according to national standards. The test platform is mainly made up of testing equipment. The system include the Tensile testing machine, High-current generator, over pulleys, Aeolian vibration system, electrical resistance instrument, etc. the DC These machines are more reasonable than before because of designing carefully.The ACCC is many good mechanical properties. The tensile force at high temperature, the grip at high temperature, the relationship between sag and temperature , the perform at vibration etc. We can conclude lots of better performance after the test. In addition, we can expect more accurately the life of ACCC by the test results.The ACCC is lots of good electrical performances. These are the test of DC resistance, the test of an aluminum resistivity, and the capacity of current of an ACCC, the occurrence of the corona at high voltage and other electrical performances. So, we can prove that the ACCC have better performances at high temperature and high voltage. The current capacity of ACCC is double the general ASCR under normal running. We can also conclude that the ACCC have a higher occurrence voltage for corona and a lower radio induced voltage. In all, The test is the basis of the ACCC running in general grid.
