Why Choose the Cembre MT70S-GC Medium Voltage Copper Connector?
The Cembre MT70S-GC, manufacturer code 2541730, is a professional blind butt connector for medium voltage copper conductors designed for dependable cable jointing in electrical power distribution systems. As part of the Cembre MT-GC series, it is manufactured from high-purity electrolytic copper and is suitable for splicing medium voltage copper cables in applications up to 35 kV.
Designed for copper conductors with a cross-section range of 63–70 mm², the MT70S-GC incorporates a central stop to assist accurate positioning of conductors during installation. Chamfered barrel entries simplify conductor insertion, while the connector's circular crimping geometry is designed for secure compression using suitable Cembre tooling.
The MT70S-GC has an overall length of 70 mm, an internal diameter of 11 mm and an external diameter of 20 mm. Its annealed electrolytic copper construction and tin-plated surface improve compressibility, mechanical performance and corrosion resistance, making it a dependable solution for medium voltage cable jointing.

Reliable Connections for Medium Voltage Copper Cables
Medium voltage compression connectors provide a permanent method of joining copper power cables while maintaining electrical continuity and mechanical integrity. The Cembre MT-GC design uses a central stop to position both conductors correctly within the connector, while chamfered ends help guide stripped conductors into the barrel before compression.
The MT-GC series is manufactured from high-purity electrolytic copper and undergoes annealing and electrolytic tinning to improve compression characteristics and resistance to mechanical stress. The design also incorporates a tin diaphragm, helping prevent migration of compound when joining impregnated paper cables to solid-insulated cables where required.
Typical Applications
- Medium voltage copper cable joints up to 35 kV.
- Electrical power distribution networks.
- Industrial medium voltage installations.
- Utility and infrastructure cable systems.
- Switchgear and power distribution equipment.
- Jointing of compatible medium voltage copper power cables.
