Copper bus SMT
Dignity
Copper bus reliable, durable, inexpensive, functional, with significant temperature changes from -200°C to +250°C. it has high thermal and electrical conductivity, resistance to atmospheric and soil moisture. It is very plastic, easily cut, drilled, is available to any types of soldering and welding. Ease of installation, aesthetic appearance, long service life and safety — make copper bus extremely beneficial to use. In addition, usually copper products after utilization are re-used.
Production
Copper bus produce rectangular cross section, extruded ingots or pieces of copper wire rod. Used copper alloys: M1, M2, M3, chemical composition of the normalized GOST 859−79. Tire produce solid, semi-solid or soft. The surface must be clean, smooth, without noticeable defects. Possible presence of traces pullback.

Copper bus imported
Foreign suppliers: VBS (Serbia), MCM (Germany), LUVATA (Finland). Tires from these manufacturers are of the highest chemical purity and electrical advantages, the exact observance of parameters, excellent electrical conductivity (58,1−58,3 MS/m).

| Standard | Mark | Kind | Note |
|---|---|---|---|
| DIN 1787 | Cu-OF, Cu-OF1, Cu-OFE | Oxygen free copper busbars | High ductility and resistance to hydrogen embrittlement |
| EN-13 601 | Cu-ETP, Cu-ETP1, Cu-FRHC | Flexible bus of oxygenated brands | Requires protection from hydrogen embrittlement |
| EN-13 601 | OF-OK | Killed of irritation, or desoxynivalenol oxygen-free copper with the addition of silver | Increased softening temperature. |
Use
Modern industry is unthinkable without copper bus, bus bars and flat conductors in the installation of electrical circuits or switchgear. Can not do without it today, no radio or electrical engineering. Bus OFC is indispensable in nuclear energy, in vacuum engineering and the aerospace industry, linear accelerators, etc.
