Tinned bus shmm
In cases where it is impossible to use conventional copper bars include chain tinned copper bus. It prevents the occurrence of induced electricity in the area of contact galvanic couple. For example, if you want to connect the transformer output voltage aluminum used tinned copper bus, ensuring optimal contact. The structures located in the open air tinned copper bus is able to provide a reliable supply of power and it does not create an arc, which is characteristic of oxidised.
Tinned copper bus is made of copper wire rod, extruded ingots and billets. Used copper alloys such as M1, M2, M3, with the chemical composition according to GOST 859−79. The tire can be a solid, semi-solid and soft, and with increased surface cleanliness. Coating with tin-bismuth, tin-lead thickness of 0,01 mm.
Outdoors with time the surface of pure copper is oxidized. Oxide deposits impede conduction, there is overheating, which further accelerates the oxidation. This leads to the formation of electrical contacts to arc and destroy them. The tin coating gives the following. Tin as a soft metal ensures a tight electric contact, which prevents further oxidation. Tinned bus is easy to install, reliable, durable. Dynamic stability and conductivity higher than that of the cable section nalogichnogo. It has a high electrical conductivity (16.7 mkOmxmm 2 / m), resistance to moisture action. It is flexible, available to any machining without the use of sophisticated equipment, is easily soldered and welded.
