FIELD: electricity.
SUBSTANCE: proposed device relates to the field of cable lines load-bearing metal structures. Made of sheet metal electrical installation product comprises a two-layered section (4, 7-9, 11, 12, 14, 15) formed by layers of two separate sheet elements, which mutual position is fixed. At that, said two separate sheet elements are made of the corresponding two different metals (alloys), differing in resistance to non-static mechanical loads. Difference of two different metals in the resistance to non-static mechanical loads can be determined quantitatively by reference books of technical information or by test results under the same conditions, according to the specifications of the manufacturers.
EFFECT: enabling increase in the electrical installation product stability to mechanical non-static loads (shocks, vibrations, seismic influences) in comparison with the known analogues, made of sheet elements of the same thicknesses.
