Copper bar perforated

Technical characteristic

Perforated copper bars greatly simplify the installation of electrical distributors. This is its main area of application. As for what particular copper alloy is used in this case, it all depends on the requirements for the properties of the product. If we are talking about standardized products, the main document is GOST 434-78, which specifies all the basic characteristics of the material. Perforated copper bars of M1 grade have specific electrical resistance from 0,01748 to 0,01790 Ohm. Other parameters of technical characteristics are regulated by GOST 434-78. Perforated copper bars are effectively used in electrical engineering. They have good flexibility; high corrosion resistance, -reliability of connection, absence of heat loss. The advantages of the busbar can be improved by tinning or silvering. In some types of connection perforated busbar is the best option. Perforated copper bus bar has a light weight, wear resistance, high electrical and thermal conductivity, durability, reliability. It is resistant to corrosion. Tires of this type are very economical, easy to operate and maintain. They easily deform. After disposal - can be recycled.


Production is regulated by TU 48-0814-105-2000 and National Standard 434-78 using copper grades M1, M0b, M2 with the chemical composition according to GOST 859-2001. The process of sampling for control composition is regulated by GOST 24 231-80. When selecting tires pay special attention to their appearance - all surfaces must be matte, clean and bright. The edges must not be delaminated or have any cracks or burrs.


When buying pay attention to marking - this will indicate the purity of the alloy and composition of alloying elements. For example, hard tires will be marked as SMT, while soft tires will be marked as SMM. The M0b grade corresponds to oxygen-free copper with an extremely low content of impurities. Such tire can be easily subjected to plastic deformation and soldering. Marking M1 or M2 corresponds to a high percentage of oxygen content.

Applications for

Electrical engineering, nuclear power industry, mechanical engineering, installation of any kind of busducts. Also widespread copper flexible braided bus bars are used in production of linear gas pedals, equipment intended for space, vacuum equipment, manufacturing of parts for linear gas pedals and electronic devices, switchgears.
