Why Choose the Cembre 2531510 CA70S-2M12 High Voltage Copper Terminal?
The Cembre 2531510 (CA70S-2M12) is a professional-grade two-hole high-voltage copper compression terminal designed to provide a secure, low-resistance electrical connection for 70 mm² copper conductors. Developed for medium-voltage cable terminations up to 35 kV, it is ideally suited for switchgear, substations, transformers, renewable energy installations and industrial power distribution systems.
Manufactured from greater than 99.9% pure annealed electrolytic copper and finished with an electrolytically tin-plated coating, the terminal delivers outstanding electrical conductivity while providing excellent resistance to corrosion. The absence of an inspection hole helps prevent moisture and dirt ingress, making it particularly suitable for outdoor and medium-voltage installations.
The CA70S-2M12 incorporates a robust two-hole M12 palm with 44.5 mm fixing centres, providing superior stability under vibration and electrodynamic forces. When installed using compatible Cembre hydraulic crimping tools and dies, it provides a reliable, maintenance-free electrical connection for demanding industrial environments.
