Electrical resistivity fehrali
You are interested in a specific electrical resistivity of fehrali? Supplier KMZ offers to buy at a economical price resistant to a wide range of brands and profiles. Guaranteed product delivery at any address specified by the consumer.
Assortment
Terralavoro assortment of products include wire, strip, tape according to GOST 12766−90 with annealed or oxidized surface, depending on the size of the cross section of hire. The wire diameter up to 0.4 mm may, at the request of the consumer made with insulation and surface treatment.
Choice
Brand fehrali is selected depending on the maximum temperature (from 600 to 1400°C), pepper square cross-section hardness/ductility. The permissible variation in the indicators of electrical resistivity should not exceed 5−8%.Indicators electrical resistance fehrali considered in the design of heating elements and electric furnaces.
Specific electrical resistivity of
The dependence of the electrical resistivity of the material, temperature and parameters of the cross-section is installed GOST 12766 1−90 (wire), GOST 12766 2−90 (tape) and GOST 12766 3−90 (band). The permitted deviation of the resistivity from fehrali rental is available in regular quality (1) high quality (PC). Allowable deviation of electrical resistivity of 1 m of material from the nominal values should not exceed ± 5% for terralavoro rental of high quality, and ± 7% for terralavoro rental of ordinary quality. The variation of electrical resistance within a single party should not exceed 4%.
