Tin Plated Copper Bar

Bus bars can have a cross sectional area of as little as 10 mm2 but electrical substations may use metal tubes of 50 mm in diameter 1 963 mm2 or more as bus bars for rigid electrical connections tinned coated copper bus bars offer a very efficient solution.

Tin plated copper bar.

Atotech used to offer and may still offer their alstan process for plating aluminum directly with tin skipping the copper plating step. When working with copper bus bars plating is essential not only for longevity but also integrity and safety. Tin plating parts allows for exceptional solderability for power electronics. However bare copper bar begins to oxidize at higher temperatures and copper oxide has poor electrical conductivity.

Yes entire manufacturing plants have been devoted to making aluminum bus bar and plating it with copper. For both tin and silver plating anti tarnish is important to keep the surface clean and conductive. Tin plating is the most versatile finish for copper bus bars. Tin plated bus bar.

When you choose storm to perform electroplating services you ll regain control over quality and mitigate exposure to extended lead times. Tin plated copper busbar helps upgrade design and provide the best quality for switchgears switchboards electrical panels power transformers and busducts by. So both tin directly on aluminum and tin on copper on aluminum are common. Hence the flashed bars can reach higher temperatures without degrading and losing their conductivity.

Silver should be used for moving bus bar parts in which arcing may be a concern. Since 1999 storm has been electroplating right on premises. Therefore copper busbar is usually plated. Tinned copper earth bars could be used in external applications or where atmospheric conditions are more severe than normal i e.

The tin and silver flashing are more resistant to oxidation than bare copper. Tin is a soft white metal which can readily be polished scratch brushed or flowmelted to give a bright finish. High humidity or moisture content areas and marine and offshore saline atmospheres. Tinning protects the copper and protects the earth bars from the formation of copper oxide tin effectively prevents oxidation.
