Corporate Information


In 1893 two immigrant engineers from the United Kingdom, Charles Henry Cawse and John Malcolm, founded the company Cawse and Malcolm (Pty) Ltd. At the time operating as Mining Brokers and Agents, they established the SA Mining and Material Exchange, a periodical publication that organized the market place for the buying and selling of used and refurbished machinery for the mining and general industry. Progressively over the years the focus of the company has changed, and it is now focused on the supply, repair and refurbishment of low voltage, medium voltage and high voltage electrical equipment, transformers and switchgear.

In order to bring the company in line with the current market environment, particularly with regard to South African BBBEE legislation and requirements, it was necessary to start a new company and in 2011 Cawse and Malcolm Electrical (Pty) Ltd was born.

Cawse and Malcolm companies have been in the Malcolm family for 4 generations and the company remains a family business – something we are very proud of.

Cawse and Malcolm Electrical (Pty) Ltd is based in the Southern Suburbs of Johannesburg, South Africa where we have 5000m2 of factory space for production and storage on 16000m2 of land.

Our well-equipped workshop facilities include a mechanical workshop for the manufacture and repair of transformer tanks and sheet metal enclosures, a paint shop, and full workshop and testing facilities for the manufacture, repair, and refurbishment of transformers up to 25MVA with 66kV primary. Alongside our transformer workshops we also have facilities for testing, repairs and modifications to MV and HV switchgear, electric motors, and the building of electrical panels.

We have established relationships with respected suppliers internationally that allows us to supply and support dry-type transformers up to 30MVA 33kV and oil filled units in excess of 200MVA and 400kV.

We have in-house design and planning capability for transformer design, switchgear and electrical panel layouts, substation design, and equipment specification and a network of experts in various fields on whom we can call to ensure that we offer a complete solution to our clients. Print
