This wire is used as ground wire (lightening wire) and lead of overhead electric power line,carrier cable and ground wire of electrified railway contact wire.Except for being used in laying common power transmission line,it is also applied in laying lines in big spanning line,cold area or are with harsh climates and circumstances,due to its excellent cold resistance and high strength.It has such high strength sound anticorrosion,less pad control,uniform frequency,lower noise level,being able to select length of sound intensifying area and low communication cost.The calculated breaking force of this wire is equal to 90%of sum of that of all monglines.
