Wire of PS, PS-25,35,50,70.

Multiwire wires from one metal are produced by twisting separate a provolok in the order established by a wire design. Number twisted a provolok and cross section of each wire determine the general section of a wire. Multiwire wires are carried out mainly by a navivka on one central wire of the subsequent poviv (ranks) of a wire.

The wire of steel PS the Wire steel TU 14-4-661-91, multiwire for the air-lines of transfers (ALT), is made from steel by 3282-74 1 groups zinced a provolok in accordance with GOST with a zinc covering of the 1st class.

The theoretical cross-sectional area of a wire is meant as the sum of cross-sectional areas of all a provolok. Wires are issued the PS 25, PS 35, PS 50, PS 70 brands. Wire brand the Section, mm2 Diameter, mm a wire Design the Temporary resistance to a rupture of a wire, N/mm2 (kgf/mm2) the Specific electronic resistance of a wire to a direct current at a temperature of +20 °C, mm2 no more than A Ohms

Steel multiwire wires of the PS brand make from steel 3282-74 I groups zinced a provolok in accordance with GOST with a zinc covering of the 1st class by twisting separate a provolok in the order established by a wire design. Number twisted a provolok and cross section of each wire determine the general section of a wire. Multiwire wires are carried out mainly by a navivka on one central wire of the subsequent poviv (ranks) of a wire … An ultimate load at stretching of a wire of 0,065 kN, relative lengthening not less than 6, number of excesses — 6, specific electric resistance at 20C no more than 1,38 10 ~ m Ohm. A step to twist of wires from 5 and 7 provolok no more than £22> wires, and from 12 and 19 — no more than £20>.

In the name "wire ps" the abbreviation "пс" designates the material applied by production — a wire steel.
