Our name, Kehui, literally means the Application of Technology. This phrase perfectly defines the company’s commitment to technological innovation, which it accomplishes whilst achieving the highest levels of quality.
The company was founded in 1991 as a joint venture with a major US organisation, before becoming independent in 2005. It has utilised the best of Asian, European and American expertise to develop a selection of cable and transmission line fault locators. Subsequently, it produced an extensive range of electricity distribution automation equipment including GPS synchronisation, remote terminal units and SCADA systems. Substation digital fault recorders complete the T&D equipment catalogue.
Kehui also produces Switched and Synchronous Reluctance Motors in various sizes from 5 – 500kW. These extremely efficient machines are suitable for a wide range of applications. 2026 brings a new, exciting range to its portfolio – Battery Energy Storage Sytems.
Kehui was founded in 1992 and is a leader in delivering a wide range of cable and transmission line fault locators for use at all levels from low voltage distribution to extra high voltage. To supplement this, the company manufactures transient fault recorders, and GPS synchronisation.
In parallel, there is a range of battery energy storage systems covering 86 to 5000 kWh, this is complemented by a control system that can achieve a transition from the grid to local generation in less than 100ms.
Kehui also manufactures synchronous and switched reluctance motors (SynRM and SRM) in various sizes from 5–500kW. SRM machines provide alternatives to induction machines in applications where there are frequent changes in load, while alleviating harmonics and phenomena such as bearing currents. Whereas, SynRM can provide greater efficiency in conventional induction machine applications.
