Huizhou Antenk Electronics Co., Ltd. (IATF16949, ISO9001, ISO14001 certified) presents the Copper Tube End. Also known as lug terminals or cable lugs, copper tube ends are precision electrical connectors designed to terminate copper cables and wires in power distribution, control panels, industrial machinery, automotive systems, and renewable energy equipment. Manufactured from high purity oxygen free copper (T2 or OFHC grade) with minimum 99.99 percent copper content, these terminals offer superior electrical and thermal conductivity, with conductivity up to 100 percent IACS. Available in a wide range of sizes from 1.5mm² to 500mm² to accommodate diverse cable gauges, the terminals feature a cylindrical tube design with a flared bell mouthed entry for easy cable insertion and an optional inspection hole to verify proper seating. Various plating options are offered including tin, silver, gold, and nickel to enhance corrosion resistance and ensure reliable performance in harsh environments. Key specifications include working temperature range from -55 to +150 degrees Celsius, and compatibility with standard hex crimping tools. The product is RoHS and REACH compliant and UL recognized under E472792.
Applications include electrical cabinets, transformers, switchgear, distribution boxes, battery banks, inverters, solar energy systems, electric vehicle charging stations, railway equipment, shipbuilding, aerospace, and wind power installations. Usage method: strip the cable end to the appropriate length, insert the conductor fully into the copper tube end until it reaches the stop or inspection hole, then crimp using a compatible hex or indent crimping tool recommended by the manufacturer. For extreme vibration or corrosion prone environments, application of heat shrink tubing over the crimped terminal is recommended for additional insulation and sealing. Precautions: always match the terminal size to the cable cross section, never exceed the rated current capacity, and avoid reusing terminals after crimping. Advantages over competitors: Antenks copper tube ends are produced with high precision stamping and drawing processes using in house tooling, ensuring consistent wall thickness and concentricity. The flared bell mouth entry reduces wire fraying during insertion, and optional tin plating provides up to 50 percent better oxidation resistance than bare copper. Custom hole configurations, special plating, and non standard lengths are available with low MOQs of 1000 units.
Production process: in house mold design and progressive die stamping, high speed pressing on 9 Japanese and Taiwanese presses, degreasing and surface cleaning, selective barrel plating (tin/silver/gold/nickel) with real time thickness monitoring, 100 percent visual inspection for burrs and dimensional accuracy, electrical conductivity spot testing, 48 hour salt spray corrosion testing, and final QC with lot traceability. Free samples, 2D and 3D CAD drawings, and 24 hour technical support available. Contact Antenk for custom colors, plating, and packaging.
