Cable long-term current carrying capacity

  1. What is the long-term allowable current carrying capacity of the cable?

    The long-term allowable current carrying capacity of the cable is the current value when the cable conductor reaches the long-term allowable operating temperature after the heat is stabilized when the specified current is passed through the cable.

  2. What factors determine the long-term allowable current carrying capacity of the cable?

    There are three factors that determine:
    (1) The long-term allowable operating temperature of the cable.
    (2) The heat dissipation performance of the cable itself.
    (3) The condition of the cable device and the heat dissipation conditions of the surrounding environment.
