The Temperature Characteristics and Current Conducting Ability of Horizontally Curved Conductors

According to experimental results, the temperature on a horizontally curved conductor was proved to be higher than that on a straight conductor. The temperature deviation increased while the current ratio I" Cr, increasing or the curved angle oc and curved radius Ro decreasing. Where, ICr is the critical melting current. Therefore, if the maximum surface temperature is settled, for conductors of the same diameter and being made of the same material, the current conducted by a curved conductor was smaller than that conducted by a straight one. When the curved angle a was <45?? and current ratio IIICr, was 38.5%, the current decrease deviation was about 10%.
