Why Choose the Cembre 2720071 MTMA25/1 Aluminium Through Connector?
The Cembre 2720071 MTMA25/1 is a high-quality aluminium through connector designed for creating permanent straight joints between aluminium electrical conductors. It provides a dependable cable-connection solution for power distribution, utilities, industrial electrical systems and infrastructure installations where reliable conductivity and mechanical strength are essential.
The MTMA25/1 is manufactured specifically for aluminium cable applications and is installed using a compatible crimping tool and correctly selected dies. Its robust aluminium barrel is engineered to compress securely around the conductor, producing a stable electrical connection capable of withstanding vibration, thermal cycling and normal mechanical stresses.
Designed for conductors with a nominal cross-sectional area of 25 mm², the Cembre 2720071 incorporates protective grease and filler putty to help limit oxidation, moisture ingress and corrosion within the completed joint. Its professional through-connector design makes it suitable for demanding low- and medium-voltage cable-jointing projects.

Reliable Connections for Aluminium Power Cables
Aluminium conductors require connectors specifically designed for their electrical, mechanical and oxidation characteristics. During installation, a correctly selected crimping tool compresses the connector barrel around the conductor, creating a low-resistance electrical path and a strong mechanical joint.
The protective compound within the Cembre MTMA25/1 helps reduce exposure of the aluminium contact surfaces to air and moisture. When installed using the recommended tooling, dies and preparation method, the connector provides a secure and durable joint for professional electrical cable installations.
Typical Applications
- Aluminium power-cable jointing.
- Electrical power-distribution networks.
- Utility and infrastructure installations.
- Industrial electrical distribution systems.
- Switchgear and substation cable connections.
- Repair and extension of aluminium conductors.
