Quality & Supply Chain

Design with Manufacturing Excellence

Success of a robust product cannot rely on a smart design alone, no matter how unique it is. Mature manufacturing processes and tight Quality control defined by solid Quality Assurance systems are required to provide customers with reliable performance products. RHM International understands this.

Furthermore, a product is as good as the quality consistency of its key components. RHM International has early on decided that critical components should be produced in house. This ensures a total control from raw material procurement to final product testing with materials traceability. This ensures a consistent high quality manufacturing and delivery process.

Our manufacturing know-how was developed in an ISO 9001 certified facility with a team having more than 40 years of experience in High Voltage T&D technologies and field problem solving.  All manufacturing employees receive extensive and regular training in electrical design, high-tech manufacturing, and testing.  RHM has established an enviable customer satisfaction rating by delivering top-quality products for critical applications.

The result? As of today, more than 100 000 products using the HV DryShield®  and RIF® technologies are in service.

ISO 9001

IEC, GSA or IEEE standards are commonly used as references. Our manufacturing plants are certified to ISO 9001 and ISO 14001.
