Features of copper wire production
Copper wire by domestic non-ferrous metallurgy enterprises is produced in accordance with two standards: GOST 22666−77 (stipulates the conditions for the production of copper wire, which will later be used for the production of thermocouples) and TU 17−605.492−2005 (regulates the production of copper wire of general use). In the first case, the material is produced in the range of diameters of 0.2… 0.5 mm, with only M1E grades. The cross-section of such a wire can be not only a circle. According to TU 17−605.492−2005, the wire is produced only of round cross-section with diameter from 0,125 to 16 mm from grades of copper MT, MS, MM, MTE, MME, MTB and MMB.
The standards stipulate that the production of copper wire with a diameter of up to 2 mm is made only in cassettes, the rest — in coils. Thus, the calculation of the mass of the running meter of a copper wire can be carried out in two ways, by mass of the cassette / bay, and by a tabular method.
A table for the most common diameters of a wire that does not have a surface coating (in kg per 1000 m) is given below:
|Diameter, mm||0.1||0.2||0.5||0.0 & gt; 1.0||2.5||4.0||6.3||10||16|
|Weight of one pound.||0.070||0.281||1,753||7,014||43,835||112,218||278,370||701,361||1795,483|
The weight of a copper wire having a protective or enamel coating will depend on the thickness of the coating.
Buy at a bargain price from the manufacturer of copper wire in a wide range of brands and sizes of cross-section offers the company Electrovek-steel. The supplier provides prompt delivery of products to the address specified by the consumer.
Determination of the mass of copper wire placed in a cove or cassette
According to the technical standards GOST 22666−77, copper wire wound on the cassette should not have rows, twists or knots, and the mass of material wound on the spool should correspond to the following parameters:
- For wire diameter 0.2 mm — 0.15… 3.5 kg;
- For wires 0.3 mm in diameter, 0.25… 3.5 kg;
- For wire diameter 0.4 mm — 0.30… 3.5 kg;
- For wire diameter 0.5 mm — 0.50… 3.5 kg.
Accordingly, TU 17−605.492−2005, the mass of the running meter of the wire of different sections is indicated in the table:
|Weight per linear meter, kg||0.006||0.027||0.062||0,111||0.251||0.447||1.006||1,789|
