In this article, the same basic specifications apply: (1) center bundle operates at 120 kV with respect to the outer cables, (2) filament circuits at 6000 A, (3) arc circuits at 3000 A, gradient grid, accel grids in a quadrupole configuration, multi wire control cable, flexible, 36'' centerline bend radius and hi-pot to 200 kV.Abstract:
The four Neutral Beam Injectors (NBI) on the TFTR Tokamak Test Cell (TTC) floor require twelve transmission lines to carry arc and filament power to the twelve ion sources from the basement. Also, the Neutral Beam Test Cell (NBTC) requires three lines but on the same floor through a wall. The same basic specifications apply: (1) center bundle operates at 120 kV with respect to the outer cables, (2) filament circuits at 6000 A, (3) arc circuits at 3000 A, (4) gradient grid, (5) accel grids in a quadrupole configuration, (6) multi wire control cable, (7) SF/sub 6/ environment, (7) flexible, (8) 36'' centerline bend radius and (9) hi-pot to 200 kV.read more

The numerical simulation of the heat transfer performance of NBI power transmission line
TL;DR: In this paper, the heat transfer performance of neutral beam transmission line is analyzed with CFD (computational fluid dynamics) software and the temperature of the transmission lines inserted in the snubber is obtained after numbers of pulse cycle using the numerical simulation model, and the result would provide a reliable basis for modification of NBI power transmission lines design.
