Terminal Tubular Sofamel 70 mm² M10 T-70/10

Product Description

The Sofamel Tubular Terminal 70 mm² M10 T-70/10 is a high-performance compression termination for 70 mm² copper conductors that require fastening with M10 screws. Manufactured from electrolytic copper and coated with tin, it offers extremely low contact resistance, excellent protection against corrosion, and high thermal stability under high currents. Its tubular design distributes crimping pressure evenly, maximizes the contact surface, and reduces heating during continuous operation. It incorporates an inspection hole to verify conductor insertion before crimping, providing safety and repeatability for professional assembly.

Main Features

• Accepted conductor cross-section: 70 mm² (rigid or flexible copper).
• Fixing hole: M10 for standard bolt/screw.
• Base material: electrolytic copper with tin-plated anti-corrosion finish.
• Inspection hole for visual control of assembly prior to crimping.
• Tubular geometry that increases the contact surface and reduces voltage drop.
• Compliance with IEC 61238-1-1 for compression joints.

Advantages or Benefits

• Superior electrical efficiency thanks to minimal losses at the joint.
• Longer service life in humid, saline, or vibrating environments due to its tin coating.
• Fast and repeatable assembly with suitable crimping tools; fewer reworks and downtimes.
• Mechanical robustness and thermal stability in high-current applications.
• Facilitates inspection and maintenance thanks to the conductor verification hole.

Purpose or Applications

Suitable for busbars, protection terminals, disconnectors and contactors, NH fuses, inverter/charger and UPS links, interconnections of 48 V and higher battery banks, and AC/DC distribution in commercial and industrial photovoltaic installations. An excellent option for e-mobility, light rail, and marine environments where M10 fastening, 70 mm² cross-section, and maximum reliability are required.
