Abstract
A three-conductor cable includes three cables disposed in a triangular form in a cross sectional view thereof, and a first refrigerant path at a cable center portion surrounded by the three cables along a longitudinal direction of the three cables for flowing a refrigerant for cooling the three cables therethrough. The first refrigerant path is formed along a part of each of the three cables in a cross sectional view thereof.
Claims18
A three-conductor cable, comprising:
- three cables disposed in a triangular form in a cross sectional view thereof;
- a first refrigerant path at a cable center portion surrounded by the three cables along a longitudinal direction of the three cables for flowing a refrigerant for cooling the three cables therethrough;
- and
- a cable supporting member for supporting a positional relationship of the three cables,
- wherein the first refrigerant path is formed in the cable supporting member along a part of each of the three cables in a cross sectional view thereof,
- wherein the three cables each comprise a second refrigerant path formed along a longitudinal direction of said each of the three cables for flowing the refrigerant therethrough, and
- wherein the first refrigerant path and the second refrigerant path are connected with each other at an end portion thereof such that the refrigerant is commonly flown through the first refrigerant path and the second refrigerant path to allow the common refrigerant to reciprocate through the first refrigerant path and the second refrigerant path with using one of the first refrigerant path and the second refrigerant path as an outgoing path and another one of the first refrigerant path and the second refrigerant path as an incoming path.
