A, induction melting furnace transmission line classification: mainly divided into cable and copper row two categories . The cable is easy to install and safe to use, but the cross-section utilization is low; the copper row is the opposite. We recommend the preferred cable as the intermediate frequency transmission line.

B, cable

It is preferable to use a coaxial cable for the transmission of the intermediate frequency current, but in practice, the power cable is often used because of the high cost. In order to make full use of the cable cross section, four cores should be preferred, followed by a two-core cable. The rated working voltage of the cable is 1000V. Cable specifications are selected according to Table 4. The total number of round-trip cables should be greater than 2 X ( maximum intermediate frequency current) / single cable allowable current
