The DTL-F Square-Head Copper-Aluminum Terminal provides robust bimetal connectivity for high-current electrical systems, engineered with precision cold-forged T2 copper and L3 aluminum alloy to mitigate galvanic corrosion risks while ensuring <5μΩ contact resistance at copper-aluminum interfaces. Featuring dual-bolt fixation and conductive gel-filled chambers, this CE-certified terminal delivers 35% higher current density than standard models, specifically designed for aluminum-cable-to-copper-equipment transitions in industrial switchgear, solar combiner boxes, and rail traction substations. Its reinforced square-head profile withstands 12kN mechanical stress, making it ideal for vibration-prone environments like wind turbine nacelles and EV charging cabinets. Compatible with 10-500mm² conductors, the DTL-F streamlines installations in smart grid retrofits and marine power systems, reducing junction failures by 53% in salt-spray tests while meeting IEC 61238-1 standards for 25-year maintenance-free operation.
