Test Results:
When designing flexible links into bus systems for the transmission of medium to high amperage currents, several factors must be considered. Some of these concerns should be: Damage due to heat expansion or vibration, voltage drop requirements, aluminum or copper materials, bare or plated contact areas, equipment misalignment problems, corrosion resistance, and the use of laminated or braided shunts. Watteredge-Uniflex can help you answer these important questions concerning flexible jumpers.
There are also several manufacturing methods available for the production of flexible jumpers. Some of these methods include the following: Cold forming a seamless tube around the material, welding the flexible material between two plates, soldering, a combination of two or more of the above, or press welding the material into a single homogeneous mass. This last method has several advantages over all the others, and is only available from Watteredge-Uniflex.
Recent tests by two independent laboratories, EMEC Consultants in Export Pennsylvania and Southern Electrical International Division of Georgia Power, confirm the superior quality of the press weld connection. Resistance values are equal to that of a solid bar of the same cross section. Even more impressive is the fact that the resistance does not increase over time as does the resistance of a riveted or compressive type connection. Even when repeatably exposed to a highly corrosive salt spray and overloaded to 200% capacity does the resistance increase.
