Description
Summary:HTS transmission cables offer an innovative transmission line that differs from conventional technologies because HTS cables can send bulk power with extremely low loss. The HTS cable will contribute to energy saving and the prevention of global warming technologically. Reduction of cable loss is the most important development in economical cables for power networks. Today, second generation (2G) wires, such as an YBCO tape, are considered to have the potential to reduce AC loss. We developed YBCO power cables and succeeded in reducing AC loss to one-sixth the loss of BSCCO cable. According to our estimations, the total loss of an YBCO cable will be half the conventional (normal conducting) cable but yield the same power capacity.
