Northern Powergrid Adopt Environmentally Friendly Greenovoc Paint

Northern Powergrid has adopted the innovative, environmentally friendly Greenovoc Speacility Coating for all its transformers and HV plant painting after carrying out trials with Rosh Engineering.

Rosh Engineering Awarded ISO45001 Standard for Health & Safety

Great achievement for Rosh Engineering to have been awarded the new ISO45001 standard for Health & Safety which supersedes the OHSAS18001 which we have held for more than 12 years. Both OHSAS18001 and ISO45001 share a common goal: to reduce workplace injuries, illnesses, and deaths. The biggest difference between the two standards is how they approach that goal. Specifically, the new ISO45001 standard emphasises a more holistic approach to safety risk management — one that is integrated into an organisation’s core business processes.

Roy Dormer 1928-2020

The founder of Rosh Engineering, Roy Dormer died on 9 April aged 91. He had just lived as many years as he could and it was not COVID-19 related. Having left school at 15 he went to night school to further his qualifications before joining Brush Transformers Ltd in 1950. On becoming Chief Test Engineer and Quality Manager his love of transformers grew into a passion. His work led to the discovery of where the hottest spot on a transformers active part really is through to thermal design work that resulted in changes to the American standard. He later became MD of a transformer cooling manufacturing plant in the North East before starting Rosh Engineering in 1981. Even into his 80s he loved nothing more than helping young engineers at Rosh, sharing his wisdom and love of the grey boxes that quietly hum and too many just take for granted.
