Title:
CRYOGENIC CABLE TERMINATION CONNECTOR
Document Type and Number:
WIPO Patent Application WO/2011/096348
Kind Code:
A1
Abstract:
Provided is a cryogenic cable termination connector having a small heat inflow from the outside and stable electrical insulation properties.
The cryogenic cable termination connector has a lead-out conductor (3) led out from a site at a very low temperature to a site at room temperature via a liquid refrigerant layer (5), a refrigerant gas layer (4), and an oil layer (2). The lead-out conductor (3) is provided with a capacitor-cone insulator (34) in which a plurality of metal foils (35) for dividing an electric field from a high voltage level down to the ground voltage level are stacked through an insulator. Among electric field tilting portions in which voltage changes gradually from the high voltage level to the ground voltage level, an electric field tilting portion positioned at a lower part is located in the liquid refrigerant layer (5) and an electric field tilting portion positioned at an upper part is located in the oil layer (2).
