FIELD: heating.
SUBSTANCE: circulation system for cooling of cryogenic cable comprises redundancy unit (1), in which cooling agent is stored, and section (4) of cable cooling, which cools cable with the help of cooling agent sent from redundancy unit (1), and cooling agent supplied from section (4) of cable cooling, is again returned into redundancy unit (1) for circulation. System has mechanism (2, 5) for control of cooling agent temperature for maintenance of permanent quantity of cooling agent in redundancy unit (1) that includes detector (5) registering cooling agent temperature, and heat exchanging unit (2), which controls cooling capacity in compliance with result of detector registration (5).
EFFECT: reduction of redundancy unit dimensions, no necessity to use traditional mechanism for control or function of cooling agent quantity in redundancy unit.
