Power Contact Band for switchgear applications

weftron LOUVER_tron® 108

is a high performance composite type contact band within the weftron.com product line of
Low Resistance - High Power Contact Elements.
Multiple consecutive silver plated copper contact plates with a 3.3mm spacing are mounted on a sprung beryllium copper band. Thus separating the function of the contact spring from the function of the current path. Therefore this electrical power contact band provides the essentially neccessary spring force required for high performance connections. Hence introducing precisely defined multiple contact points in the electrical connection when used in between two mating conducting surfaces. Consequently the number of contact plates, the associated metal components and the ambient conditions define the electrical performance characteristics of this  high power contact band.
Especially the separation of the contact spring function from the electrical conduction function gives LOUVER_tron® 108 an exceptionally high current carrying capacity.
Aditionally the larger mass of the copper contact plates provide better heat sinking. So the operating temperature inside the connection will remain lower. Thus reducing the rise of contact resistance.
Technical parameters of LOUVER_tron® 108 are in the table on the backside of the data sheet. So depending on the application LOUVER_tron® 108 contact band may be used either in flat or in circular shaped connections.
For different requirements weftron offers a variety of application specific options. Please consult us for any of your projects involving connections with special requirements.
