In view of the use requirements of wires in different environments,it is particularly important to understand their current carrying capacity performance. Through experimental design,a number of wire working environments that simulate practical application scenarios are built,and the trend of current carrying capacity of wires in different envi-ronments is compared. The maximum sustainable and safe working current range of wires in normal temperature envi-ronment,high temperature environment and low pressure environment is further studied. Through theoretical analysis,the reasons for the decrease of current carrying capacity of wires in high temperature environment and low pressure environment are understood,which provides important reference value for the safe application range of wires in vari-ous environments,so as to maximize the use of the transmission capacity of wires and meet the needs of use.
