With the rise of electrification and automation in the mid-20th century, slip rings were gradually being used in electric motors and generators, especially in South Africa. This can be traced back to the country's growing industrial and mining sectors. The South African mining industry is one of the largest in the world, driving the development of power transmission systems, including slip rings for draglines, cranes, and conveyor systems.
In the 1970s and 1980s, local companies such as RWW Engineering and Marthinusen & Coutts began to develop slip rings for industrial applications to meet high voltage and high current requirements. The increased reliance on rotating electrical equipment in industries such as manufacturing and power generation drove innovation in slip rings, including performance in harsh environments.
By the early 21st century, the slip ring manufacturing industry in South Africa had diversified to serve industries such as renewable energy, automotive and aerospace. Local companies also continued to improve their products. For example, companies such as M-Tek have developed advanced slip rings for defense and aerospace applications. This marked an evolution in local engineering capabilities.
Today, South African manufacturers continue to innovate and provide slip rings to industries ranging from mining to renewable energy, making the country a key player in slip ring technology on the African continent.
