Millions of people on the African continent still lack access to electricity and after a decade of fragile improvement, access to electricity on the continent had fallen by 4% between 2019 and 2021. Energy drives economies, sustains societies and is essential to reduce poverty. Access to electricity enables investments, innovations and new industries that are the engines of employment, inclusive growth and shared prosperity. Quality transformers are an essential ingredient in achieving SDG-7 targets.
BTT implements its boldness with the vision of a smart factory with systems that self-optimise performance across the production flow, self-adapt to and learn from new conditions in real or near-real time, and autonomously run certain parts of production processes, under an Internet of Things (IoT) solution. BTT has world class transformer design software, which allows for optimization of designs according to the parameters required, the materials available and their cost bases, and finally the specific manufacturing capability they employ. The software produces highly optimised result, saving an average of 10% of the bills of material and producing a transformer with lower losses, which benefits the grid. The cost saving and technology advances are subsequently passed on the end-users, strengthening BTT’s manufacturing competitiveness.
BTT’s bold vision includes the final implementation of the factory quality management system, operating on Radio Frequency Identification (RFID). This system tracks both materials, manufactured products, assembled transformers and people in the facility and orchestrates the manufacturing process. The system includes customised software that leverages RFID tags and readers to automate much of its data capture. The system guides operators and ensures that all required steps and quality verifications are performed with comprehensive traceability at key points along the way.
BTT’s transformers are designed and manufactured from start to finish at its workshop in Meyerton, South Africa. BTT’s electrical and mechanical engineers design transformers with the lowest losses and lowest total cost of ownership, whilst adhering to the latest version of the applicable technical specifications. Each unit is manufactured according to the client’s unique specifications.
• BTT manufacturers transformers from 16kVA up to 10MVA, single or three phase, step up or step down, single or dual ration, oil filled or dry type, copper or aluminium winding
• BTT manufactures mini-substations, under license from an international pure play manufacturer, from 200kVA up to 1000kVA, Type A or Type B, with Ring Main Unit (air, oil or gas)
• BTT manufactures renewable transformers, including solar photovoltaic, water and wind application transformers
Our manufacturing philosophyBuild To Transform
BTT’s core fabrication process is fully certified by ISO. Quality is not negotiable and the core forms the heart of any transformer. With state of the art precision machinery, BTT’s cores are slit and cut to be fit for purpose and beat with endurance and power. BTT’s cores are manufactured and stacked in house to ensure full quality control. BTT offers the following services:
• Slit, cut and pack up to 20MVA
• Slit, cut and stack up to 20MVA
• Customers can bring their own quality material to slit and/or cut
• Step lap cores
• Fully mitred cores
• Butt / square cores
• All cores have the maximum stacking factor
• Centre holes on limbs and yokes
BTT’s machinery ensures the best no load losses of the cores, which contributes to reducing noise emissions.
