The Copper Tube Terminal (DTG-Type) is an essential electrical fastening component designed for terminating medium to large-gauge power cables and grounding wires. Unlike tinned terminals, the DTG series features a bare copper finish, which is highly sought after in environments where direct copper-to-copper contact is preferred for absolute maximum power transmission.

Proudly manufactured under the UNIQUE brand, these DTG series copper lugs are engineered for demanding industrial environments. They are specifically recognized for their strong electrical conductivity and thickened material construction, which prevents the barrel from splitting or cracking during heavy hydraulic crimping. Whether you are building power distribution cabinets or grounding heavy machinery, the DTG-Type terminal ensures a permanent, low-resistance connection.

Exceptional Electrical Conductivity: Crafted from high-purity bare copper, these terminals provide strong conductivity, ensuring minimal voltage drop across your heavy-duty electrical networks.
Thickened Material Construction: Built with thickened copper material, the barrel walls offer superior mechanical strength. This allows the lug to withstand the immense pressure of industrial crimping tools without deforming or failing.
Complete Specifications: We offer a comprehensive range of sizes designed to accommodate cable cross-sections starting from 6 mm² all the way up to massive 400 mm² power cables.
Convenient Installation: The smooth barrel entry and flat contact pad guarantee a convenient installation process (安装便捷), allowing electricians to work faster and more efficiently.
Custom Non-Standard Capabilities: In addition to our standard sizes, we have the manufacturing flexibility to produce custom non-standard products (可定做各种非标规格) tailored exactly to your engineering blueprints.
The robust design and excellent current-carrying capacity of the DTG-Type Copper Tube Terminal make them indispensable across various heavy-duty sectors:
Power Distribution & Switchgear: Terminating thick main feeder cables inside electrical panels, transformers, and breaker boxes.
Grounding & Earthing Systems: Providing highly conductive bare-copper bonds for heavy industrial grounding grids and lightning protection systems.
Heavy Machinery & Motors: Securing vibration-resistant power connections to large electric motors, generators, and factory automation equipment.
Renewable Energy: Connecting thick inverter cables and battery banks in solar power and wind energy storage facilities.
Installing DTG series Copper Tube Terminal cable lugs is a straightforward process that guarantees a professional connection:
Cable Stripping: Strip the insulation from your heavy-duty cable. The stripped length should match the barrel depth (Dimension “E” on the specification chart).
Wire Insertion: Insert the bare copper strands fully into the terminal barrel until they seat at the bottom.
Professional Crimping: Use a heavy-duty hydraulic or mechanical crimping tool equipped with the correct die size to compress the thickened barrel firmly onto the cable.
Mounting: Place the flat contact pad over your mounting stud and secure it using a bolt that matches the terminal’s mounting hole diameter (Dimension “D2”).
Uncompromising Quality: The UNIQUE brand stands for reliability. By using thickened material, we ensure that every crimp holds tight and every connection remains safe.
One-Stop Procurement: With a complete range of specifications covering 6 mm² to 400 mm², we can supply your entire project’s terminal needs in a single order.
Engineering Flexibility: Your projects shouldn’t be limited by standard catalogs. Our ability to manufacture custom non-standard products means we can adapt hole sizes, barrel lengths, or pad widths to solve your unique assembly challenges.
