FIELD: electricity.SUBSTANCE: method of cable line laying with providing of ferromagnetic shielding includes excavation of trenches for cables of one cable line circuit, bedding the trench bottom, laying of the cable line circuit, installation of ferromagnetic screen in places of local maxima of magnetic field intensity along the cable line route. The cable chamber contains the housing, supporting structures for connecting couplings inside the housing, a front cover of the cable compartment, the housing is fitted with a well for transposition of cable screens placed from outer side of the face wall of the duct.EFFECT: simplification of the process of construction of the cable line route and implementation of more reliable and safe power transmission to consumers.8 cl, 19 dwg |
