Tubular Bimetallic Terminals

Traditional lap joints create current bottlenecks at copper-aluminum interfaces, but our tubular design ensures 360° uniform current distribution by eliminating edge concentration effects. The friction-welded interface achieves 99.8% density through precision-controlled rotational forging, creating a metallurgical bond that X-ray diffraction shows has finer grain structure than explosion-welded alternatives.  

Field data from HVDC installations demonstrates consistent performance, with infrared scans showing ≤2°C temperature differential across the joint at 2000A continuous load. The tin-hard anodized finish forms a synergistic barrier system which the tin plating sacrifices itself slowly while the 30μm anodized layer provides permanent protection, reducing maintenance intervals from annual to decadal.
