FIELD: power engineering. ^ SUBSTANCE: power transmission line 1 has at least one power cable 2 and at least one shielding member 6 made of ferromagnetic material and disposed on section radially external relative to at least one cable 2. Shielding member 6 has base 10 and cover 11. Line 1 also has supporting member 7 joined at least with base 10 of shielding member 6. Ferromagnetic material of shielding member 6 is specifically chosen from group incorporating textured silicon steel, best of all that having silicon content of about 1 to about 5 percent, non-textured silicon steel, permalloy, and supermalloy. ^ EFFECT: facilitated maintenance of shielding member in operation, enhanced effectiveness of weakening magnetic field. ^ 41 cl, 11 dwg |
