Application

In cases where conventional copper bars cannot be used, a tinned copper bar is included in the circuit. It prevents the occurrence of induced electricity in the contact area of the galvanic pair. For example, if you want to connect a transformer with an aluminum voltage terminal use a tinned copper bar, which provides an optimal contact. In constructions located outdoors tinned copper busbar can provide a reliable supply of current and do not create an arc, which is characteristic of oxidized contacts.

Manufacturing

Tinned copper bars are made from copper rods, pressed ingots and billets. Copper alloys used include: M1, M2, M3, with chemical composition according to GOST 859-79. The tire can be hard, semi-hard and soft and with high purity surface. Tin-bismuth, tin-lead coating with thickness of 0,01 mm.

Advantages

Pure copper surfaces oxidize in the open air over time. Oxide deposits make conductivity difficult and overheating occurs which further accelerates oxidation. This leads to arcing of the electrical contacts and their destruction. Tin plating gives the following. Tin as a soft metal provides a tight electrical contact that prevents further oxidation. The tin-plated tire is easy to install, reliable, and durable. Dynamic stability and conductivity is higher than that of a cable with a taxing cross-section. It has high electrical conductivity (16.7 ^μOhmxmm2/m), resistance to the action of high humidity. It is malleable, available for any machining without the use of sophisticated equipment, easy to solder and weld.
