2 Product Overview
The HUP Series DT-type copper tube cable lugs are designed for reliable compression termination of copper conductors in power distribution and control applications. Manufactured from C11000 99.9% electrolytic copper and fully tin-plated, they provide excellent conductivity and corrosion resistance.
Compliant with DIN 46235 and EN 13600, these tubular terminals are suitable for conductor classes 1, 2, and 5 per IEC 60228, covering a wide range from 6 mm² to 1000 mm². The one-piece seamless construction ensures uniform compression and reliable electrical contact.
Each lug is designed for hexagonal crimping per DIN 48083-4, ensuring consistent mechanical pull-out force and electrical performance. The tin-plated finish provides long-term corrosion protection in demanding environments, including humid, marine, and industrial atmospheres.
Manufactured to rigorous quality standards under the management of SORIVO, each batch is tested for dimensional accuracy, material purity, and crimping performance. For detailed company information, please visit sorivocable.com/about-us/.

5 FAQ
What is the difference between DT-type and other cable lug types?
DT-type (DIN Tubular) lugs have a seamless tubular barrel designed for compression crimping. They are distinct from fork-type, ring-type, or pin-type terminals. DT lugs per DIN 46235 are the standard for medium to large power cable terminations.
What crimping tool should I use with these lugs?
These lugs are designed for hexagonal compression crimping per DIN 48083-4. Use a hydraulic or manual crimping tool with the appropriate die size matching the lug barrel diameter. Indent crimping is also compatible.
Are these lugs suitable for fine-stranded (Class 5) conductors?
Yes, these tubular lugs accommodate Class 1 (solid), Class 2 (stranded), and Class 5 (fine stranded) conductors per IEC 60228. For very fine Class 6 conductors, we recommend using a ferrule or reduced-barrel lug.
What is the temperature rating of these lugs?
Copper tube lugs with tin-plated finish are rated for continuous operation up to +105°C. The temperature rating matches standard PVC and XLPE cable insulation ratings. For higher temperatures, silver-plated or bare copper variants are available.
Can I get lugs with specific bolt hole sizes?
Yes, each cable cross-section is available with multiple bolt hole diameter options (M5 to M20). Standard sizes follow DIN 46235 tables, but custom hole sizes and multi-hole palm configurations can be manufactured to order.
