Founded in 2008, KonNx (formerly JoynX) supply high voltage cable couplers to all mining and mining excavation operations and projects, and have a non-ferrous foundry and machine shop to serve customers more efficiently. KonNx and partner companies have extensive experience in the industry and have become the world leader for the design and manufacturing of high voltage cable coupler systems that offer an unmatched level of reliability and safety.


KonNx (formerly JoynX) has more than 30 Years experience in the design and manufacturing of High Voltage Coupler and Adaptor Systems ranging between 6.6Kv to 35Kv. The 12Kv Flameproof System is the Winner of the Innovative Product Award given by SAFA. This equipment can be used in underground and opencast mines as well as in any harsh environment.

Our product design is of such nature that it is homogeneous with the cable and therefore eleminates phase to phase faults.

The Coupler and Adaptor Systems are the safest and most reliable in the world and feature:
- Phase Segregation
- Insulating Materials
- Removal of Air
- Partial Discharge
- Superior Silver Plated Contacts

The systems are designed and manufactured in our foundry located in Booysens Reserve. Our couplers and adaptors are supplied locally as well as globally.
