Power cord the Ruo selection and access? AC input power cord selection and access? The power cord access equipment. Should be used convergence of strong copper nose. Wire and top-head temperature. Should not surpass 70 degrees Celsius.
Aluminum and copper data convergence, the use of copper and aluminum transition joints is necessary in order to avoid copper, aluminum contact points because of the electrical erosion effect of a larger contact resistance, incurred when power is applied to converge at the fever, and even a fire broke out.
AC power cord cross-sectional area according to the safe carrying capacity (ie, fever premise) to select. I is a useful value of the conductor current, J is the conductor current density.
