Wires GOST

Rated cross-section cable is part of the conductor through which the current passes.The cross section is defined by a circular formula, if the section through the wire round and has a single wire.If, however, on a section of a lot of delay, to determine the need to summarize the section of wires in the cable.

In addition to these measurements and tables, which are often used in the selection of the cable is taken into account such factors understate correct:

• equal to the cross section of the wires and the position in the block;
• at ambient temperature;
• cable designed for burying in the ground;
• the number of cables running operating near.

calculation-section

need to make calculations for what would be satisfied in the selection of the cable that it meets all safety requirements, reliability and durability.For a better understanding of calculation capacity to take slices living example is based on aljuminevoj - 2,5mm² according to GOST 22483-77 Class 1 bendability.

cross section written in the same vein 2,5mm² (S), according to GOST resistance to a length (L) 1 km at 20 ° C Rr = 12,1 ohm aluminum remote resistance p = 0,027 * 10 - 6 Ohm ∙ m.The conductors for each cable type, are made of different materials.Here are the most common ones:

• aluminum (GOST 13843-78, TU 16.705-144-80, GOST 6132-79);
• Brass (TU 16.K71-003-87, GOST 2112-79, 16.705-144-80).

cross-section of the company "Alyur»

example of high-quality manufacturing of the cable cross-section, according to feedback from customers, we can take of "Cable Factory ALYUR".

Here are examples of comments: "And yet, not for the sake of advertising, like a wire" ALLURE "and the section is kept and thick insulation," "For the installation I try to use only VVGng cable (conforming to the requirements of GOST R 53315-2009) production ALYUR", as many consumers allocate such quality plus features such as: large-section, PVC insulation, core copper, aluminum.But there are also shortcomings.

This is compared with the factory "Magna" metering cores showed the "Magna" minus 28%, the "Alyur" minus 6.8% the result of the measurement section.LLC "Cable Factory ALYUR" has a certificate of fire safety, to confirm the quality of the cable.
