Product Benefits and Applications
Typical Applications●Connecting copper-core cables to circuit breakers, air circuit breakers, distribution boxes, and copper busbars
●Terminal wiring for equipment such as motors, transformers, switchgear, and UPS systems
●Crimping of internal wires in distribution panels, and wiring of secondary and primary circuits
●Power distribution systems in industrial plants, buildings, photovoltaic, and wind power installations
●Terminal fastening and electrical connections for indoor and outdoor copper cables
Benefits
Excellent Electrical Conductivity
Made from T2 copper, it features low resistivity and high current-carrying capacity, resulting in minimal heat generation and low power loss at the connection points.
Reliable and Stable Connections
The tubular design ensures a tight fit with the wire after crimping, providing low contact resistance and preventing loosening.
Oxidation and Corrosion Resistance
The entire surface is tin-plated, providing protection against oxidation and discoloration, and ensuring no corrosion even during long-term outdoor use.
High Mechanical Strength
Provides sufficient tensile strength after crimping, withstanding vibration and wind sway for safe and reliable operation.
Quick and Easy Installation and Comprehensive Range and Versatility
Compatible with standard crimping pliers, simplifying installation and making it ideal for rapid, high-volume wiring.
Covers a full range from 10 mm² to 630 mm², compatible with various copper cables and equipment.

FAQ
Q: What is the difference between DT and OT lugs?
A: DT is a tubular compression lug suitable for multi-strand conductors. OT is an open-nose lug suitable for single-strand or solid conductors. DT has larger contact area and better conductivity; OT is more convenient for installation and can be opened on-site.
Q: Can compression lugs be soldered?
A: Soldering is not recommended. Soldering destroys material structure and plating, causing voids and cracks. Use dedicated compression tools to ensure crimp quality.
Q: Why use hexagonal compression for large-section lugs?
A: Hexagonal compression creates six-point contact between lug and conductor, with large contact area and high compression density. Mechanical strength and electrical performance are superior to point compression or circumferential compression.
Q: What is the difference between tin-plated and silver-plated lugs?
A: Tin plating has lower cost and good anti-oxidation effect, suitable for general applications. Silver plating has higher conductivity and lower contact resistance, suitable for high-current or high-frequency applications, but at higher cost.
Q: What if the conductor pulls out from the lug after compression?
A: This indicates inadequate compression or die mismatch. Cut off the compressed section, re-strip and re-compress. Re-compression or makeshift use is prohibited.
Q: Why apply conductive grease before compression?
A: Conductive grease fills microscopic voids between conductor and lug, reducing contact resistance, preventing oxidation and corrosion, and reducing operating temperature rise.
