Reyrolle was a leader in electrical manufacturing in the United Kingdom throughout the 1900’s through to about 1980. During this period there were many Reyrolle plants established outside the UK including switchgear factories in South Africa and Melbourne, Australia.
The South Africa based division of Reyrolle, a division of NEI Africa Ltd., was acquired by ABB in 2002. It included the medium-voltage part of Reyrolle South Africa.
Reyrolle's medium-voltage switchgear got an impressive reputation for quality and reliability, with a long service life. Nowadays ABB is offering extensive retrofit solutions for Reyrolle LMT, LMS, LMR and LMRP switchgear. There is a specific benefit of circuit-breaker retrofit, where the original breakers are of an oil-insulated type and there is a need to reduce fire risk in the sub-station for safety or insurance purposes. The breaker can easily be replaced with the latest vacuum or SF6 circuit breakers, enabling the switchboard to reach its full lifespan.
Reyrolle LM panels retrofitted with the Internal Arc modifications increase operator safety at a fraction of the cost of new switchgear with minimal downtime and all modifications done on site.
