Cuponal Busbars is the bimetallic conductive busbar of copper-clad aluminum and  a kind of "new conductor material", which has the excellent electrical conductivity of copper and the low density of aluminum.
The cuponal busbars produced by Signi Aluminum  is different from the traditional hydrostatic extrusion method, rolling and crimping method, cladding welding method, casing rolling method and other traditional production processes, and adopts the original “level continuous casting high-efficiency molding— - Rolling technology, cuponal busbar bonding interface achieves certain metallurgical bonding, enhances the shear strength of the two metal interfaces, ensures the mechanical properties and electrical properties of the product, and improves the product stability.



Cuponal Busbars ‘s character:
1. Electrical equipment manufacturing: mainly including low voltage, medium voltage, high voltage power distribution, busbar systems, rectifiers, motor windings, etc.;
2. Crane rail supply system, vacuum switchgear, generator set, substation, aluminum foil wound transformer, bimetal connector, etc.;
3. Wind power, solar photovoltaic field: mainly including reactors, inverters, etc.;
4. Railway, aerospace, high-speed ferry, etc.
Cuponal Busbars ‘s performance
 
1. Unique composite performance, copper-aluminum interface is metallurgical combination, high product performance, and has the characteristics of copper conductivity and aluminum density;
2. High interface bonding strength, excellent electrical conductivity, and excellent mechanical processing properties;
3. The copper layer is thick and adjustable, suitable for transmitting large currents;
4. Light weight, convenient transportation and installation;
5. Obvious economic benefits: saving copper resources and reducing production costs.
