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.

Reliable High Voltage Cable Termination

Compression terminals create permanent, low-resistance electrical connections by compressing the barrel around the conductor with calibrated hydraulic tooling. This produces excellent electrical conductivity together with high mechanical strength and long-term resistance to vibration and thermal cycling.

The Cembre 2531510 CA70S-2M12 is designed for professional installers requiring dependable cable terminations for medium-voltage electrical infrastructure. Its two-hole palm provides enhanced mechanical stability, while the sealed barrel design helps maximise long-term reliability in outdoor applications.

Typical Applications

  • Medium-voltage cable terminations.
  • Electrical substations.
  • Industrial switchgear.
  • Transformer connections.
  • Power distribution equipment.
  • Renewable energy infrastructure.

Frequently Asked Questions

What is the Cembre 2531510 used for?

The Cembre 2531510 CA70S-2M12 is used to terminate 70 mm² copper conductors onto equipment with two M12 bolted electrical connections in medium-voltage and industrial power applications.

Why does this terminal have two fixing holes?

The two-hole palm provides improved mechanical stability and greater resistance to vibration and electrodynamic forces than a conventional single-hole terminal.

Why is there no inspection hole?

The absence of an inspection hole helps prevent moisture and dirt entering the crimped connection, making the terminal particularly suitable for outdoor installations.

How is the terminal installed?

The conductor is inserted into the barrel and permanently compressed using compatible Cembre hydraulic crimping equipment with the correct die set.

Where is this terminal commonly installed?

It is commonly used in substations, switchgear, transformers, renewable energy systems and industrial power distribution installations.

Trusted by Electrical Professionals Worldwide
