Product Description
The DTL-3 series copper-aluminum transition lugs (cable terminals) are high-performance bimetallic connectors manufactured by Yueqing JASCO Electric Co., Ltd. They are widely used in power grid upgrades, industrial power supply, construction projects, and various power transmission and distribution applications.
These products utilize an advanced integral friction welding process to securely bond a high-purity T2 copper contact face with a high-purity 1060 aluminum barrel.
This design effectively eliminates electrochemical corrosion caused by direct copper-aluminum contact, reduces contact resistance, and prevents overheating during long-term operation. The aluminum barrel is designed for crimping onto aluminum-core power cables, while the copper contact face connects to copper busbars, transformers, and the copper terminals of switchgear.
Featuring stable electrical performance and excellent mechanical strength, these lugs operate reliably within a wide temperature range of -40°C to +125°C and are suitable for both indoor and outdoor 0.6/1kV low-voltage distribution systems.
The series offers a comprehensive range of specifications, covering conductor sizes from 35mm² to 400mm² with precise dimensional tolerances.
Additionally, customization options are available to meet specific requirements regarding mounting hole sizes, markings, and packaging.
