£19.20
The Cembre 2720575 MTMA25-10-GC is a high-quality aluminium reducer compression through connector (straight splice) designed to provide secure, permanent electrical joints between 25 mm² and 10 mm² aluminium conductors. Manufactured by Cembre, it offers dependable electrical performance for industrial, utility and electrical distribution applications.
Part of the proven Cembre MTMA-GC series, the connector is manufactured from greater than 99.5% purity aluminium. The blind barrel incorporates an integrated central stop together with corrosion-inhibiting grease and sealing compound to minimise oxidation while ensuring reliable long-term performance in demanding electrical environments.
Designed for reducing cable connections between 25 mm² and 10 mm² aluminium conductors, the MTMA25-10-GC is ideal for utilities, panel builders, electrical contractors and industrial maintenance engineers requiring reliable conductor transitions in LV, MV and HV cable systems.
Compression reducer connectors provide permanent, low-resistance electrical joints between different sizes of aluminium conductors. When installed using approved Cembre compression tooling and dies, they deliver excellent electrical conductivity together with long-term mechanical reliability.
The MTMA25-10-GC incorporates a grease-filled barrel, sealing compound and integrated conductor stop to minimise oxidation and moisture ingress, making it ideal for industrial electrical installations, substations and utility distribution networks.
