Our History

RHM International’s story actually started in the late 80’s when senior professionals in the Transmission & Distribution industry came up with the idea of a new approach to dry high voltage insulation, what would later become HV DryShield®. They developed it initially for wall bushings but quickly thought of a derived smart design for current transformers. Products started to be implemented in various environments in the early 90’s, to the full satisfaction of customers.

Consequently, as customer satisfaction was cemented, RHM International was created in 2004 to develop international awareness and markets.

RHM International and its sister manufacturing company are privately owned companies who have been funding their growth internally, without debt or venture capital. It results from this ownership quick decisions and a flexibility allowing timely alignment to customers’ and stakeholders’ changing circumstances.
