DTL-4 Pre-insulated Bimetal Lug

The DTL-4 Pre-insulated Copper-Aluminum Terminal establishes ultra-reliable low-voltage connections for ABC cables with dual-material engineering—99.9% pure copper palm and 99.6% aluminum sleeve—featuring color-coded elastomer rings for instant conductor sizing (10-300mm²) and UV-resistant polymer insulation validated by EN50483-4/NFC33-021 standards. Its pre-lubricated waterproof seal withstands 1-minute submersion tests at 6kV, ideal for coastal smart grid distribution cabinets and urban underground cable networks where moisture intrusion risks prevail. The integrated weatherproof design combines anti-corrosion aluminum alloy with thermal-stable insulation (-40°C~90°C), reducing installation errors by 50% through visual size identification while serving offshore wind farm switchgear and IoT-enabled street lighting systems. Compatible with hybrid conductor retrofits in flood-prone substations and industrial microgrids, this maintenance-free solution eliminates galvanic degradation through precision-engineered bimetal interfaces, achieving 25-year service life under cyclic salt spray (ASTM B117) and UV exposure.
