D-436-77

Optimized for smart grid applications, TE Connectivity Aerospace, Defense and Marine's D-436-77 delivers intelligent Terminals - Wire Splice Connectors performance for utility-scale power distribution. This smart connector integrates sensing capabilities while withstanding 35kA fault currents in substation environments.The Inline, Individual Openings (Parallel) design incorporates embedded temperature sensors that detect hot spots before failure. Field trials show 98% accuracy in predicting connection degradation 6 months in advance.Featuring Varies by Wire Size isolated channels, this terminal prevents phase-to-phase arcing during fault conditions. The segregated design meets IEEE C37.90.1 surge withstand requirements.Utilizing Crimp technology, this connector maintains <10 contact resistance at 2000A continuous load. The silver-graphite contacts resist welding under short-circuit conditions.Compatible with 779-2680 CMA utility conductors, this solution accommodates both aluminum and copper feeders. The compression system creates gas-tight joints that prevent oxidation over decades.The Fully Insulated Heat Shrink system achieves 250kV BIL rating for transmission-class applications. Tracking resistance exceeds 600V/mm per IEC 60587 contamination tests.Blue, Blue Stripe coding follows ANSI/NEMA Z535.1 safety standards for electrical hazards. The retroreflective surface enhances visibility during nighttime maintenance.
