SWER Transformers
Single Wire Earth Return (SWER) transformers are designed for rural and remote electrification, providing a cost-effective and reliable method of power distribution over long distances with minimal infrastructure. Unlike conventional single-phase or three-phase systems, SWER uses a single high-voltage conductor with the earth as the return path — dramatically reducing construction costs while maintaining a dependable power supply for communities, farms, and remote installations.
At Reliable Transformers, our SWER units are engineered and manufactured to withstand the unique environmental and operational challenges of remote regions.
Our transformers are successfully deployed across Southern Africa, including Lesotho, Eswatini, and Namibia, where they continue to play a vital role in rural electrification, agricultural productivity, and community development.
