Copper busbar electrical

Technical characteristics

The main requirements that are put forward to the characteristics of electrical copper bus bars are given in GOST 434-78. This document specifies both the varieties of possible products (oxygen-free, hard or soft), as well as technical parameters and production method. As for the load limits, the copper alloy in this form is able to conduct the current force equal to 5900/6800 V (for AC and DC, respectively). The main advantages that electrical bus bar has are good current conductivity and high mechanical strength. In addition to the fact that electrical bus bar efficiently transmits electricity, it also has a low price, which allows its mass use for industrial purposes. Recall, copper alloy provides reliable and long-lasting operation only when manufactured on modern equipment in accordance with the requirements of domestic or international standards.

Impurities

Sb, P, SІ, Bl and As in grades M1 and M0 greatly impair the electrical conductivity and are allowed in amounts not exceeding 0.002%. Impurities Sb, Pb and Bl reduce technological properties of copper, causing brittleness during hot forming. The impurities Ag, NІ, Sn and Zn are not able to have a harmful effect on the technological and mechanical properties. Depending on solidification conditions, the structure of pure cast copper is either transcrystalline or equiaxial.
