High-temp. heavy-current water-cooled cable

The utility model relates to an insulated cable which is provided with a heat radiating device and is divided by shape, more specifically to a high-temperature heavy-current water-cooled cable. The utility model mainly solves the defects of the existing like electric cables such as large electric energy loss, unsafe use, easy hot shutdown which is caused by aging and leakage, etc. The utility model comprises a joint, a copper stranded wire, a clamping hoop, a core pipe, and a center pipe which is connected with the core pipe and is arranged in the copper stranded wire. The utility model is characterized in that the outside of the copper stranded wire is provided with a stainless steel corrugated pipe, and the outside of the stainless steel corrugated pipe is provided with an insulating cover with high-temperature resistance. The utility model can be used in high temperature environment such as electric arc furnaces, electric slag furnaces and ore hot furnaces.
