The DTL-5 Copper-Aluminum Terminal delivers ultra-premium bimetal connectivity for critical power infrastructure, precision-forged with a thickened T2 copper palm (≥99.9% purity) via advanced drop-forging technology and friction-welded to 99.5% L3 aluminum sleeves, achieving 45% lower interface resistance than standard models for high-current transmission up to 35kV. Engineered for ABC cable terminations in offshore substations and heavy industrial switchgear, its conductive grease-filled aluminum barrel with hermetic dust caps prevents oxidation in coastal salt spray (-40°C~120°C) while the reinforced copper interface supports 50% higher current density than DTL-2 variants. Ideal for extreme-duty applications like steel mill rectifier systems and hydrogen electrolyzer plants, this IEC 61238-1-certified solution withstands 20kN cyclic loads in wind turbine nacelles and metro rail traction grids. The upgraded copper forging process eliminates hot spots in transformer bushing connections and nuclear facility backup circuits, offering 30-year maintenance-free operation with 55% reduced lifecycle costs versus conventional adapters. Trusted for mission-critical copper-aluminum transitions requiring unmatched conductivity and mechanical resilience under sustained thermal/electrical stress.
