FIELD: electricity.

SUBSTANCE: invention describes a passage node of power transmission to a low-temperature system comprising a contact tube section assembly. The contact tube section assembly comprises of a passage body (118) forming an inner cavity (120) extending therein between the first open end (122) and the second open end (124). The contact tube section assembly also includes the first contact plate assembly (134a) disposed at the first open end of the passage body and sealing the first open end by the first weld seam produced by electron beam welding between the first contact plate and the first open end. The contact tube section assembly also comprises of the second contact plate assembly (134b) disposed at the second open end of the passage body and sealing the second open end by the second weld seam produced by electron beam welding between the second contact plate and the second open end.

EFFECT: creating an improved passage node in installations with low-temperature fluids.
