Diverse Cooperation Models · Join Hands for a Win-win Future
TSTY Electric offers three flexible cooperation paths: "direct procurement, bidding cooperation, and agency franchise", catering to the diverse needs of different customers. Relying on mature cases and a complete support system, it helps partners create value together.
We provide a full range of transformer products and customized solutions to meet the immediate procurement needs of end customers such as enterprises and engineering parties. Whether it is standard model products or customized equipment suitable for special scenarios (such as offshore wind power, high-temperature and high-humidity environments), they can all be directly connected through official channels. We support flexible order configuration, rapid production scheduling and global logistics distribution, combined with full life-cycle after-sales service, to ensure that the equipment can be put into use quickly.
Actively participate in various bidding projects of the government, state-owned enterprises, large-scale engineering, etc. With stable product quality, compliant technical parameters and perfect service plans, successfully win bids for key projects many times. For instance, in the De 'A Wind Power Plant project in Africa, we strictly submitted technical documents and quotation plans in accordance with the tender requirements. With product quality that met local standards, an efficient response capability to deliver and install within 30 days, and reasonable quotations, we ultimately won the bid and successfully completed the project delivery, earning high recognition from the client. The entire cooperation process is standardized and transparent. We can provide complete qualification documents, performance certificates and technical support to facilitate the smooth progress of the bidding project.
We are recruiting regional and industry agents globally. Currently, we have established mature agency systems in countries such as Nigeria, Kenya, and Ethiopia, forming a win-win model of "headquarters support + local operation". We offer comprehensive empowerment to our agents, including free technical training, multilingual solution support, marketing material supply, exclusive regional authorization protection, as well as shared global logistics networks and after-sales resources. For instance, a certain agency partner in Africa, leveraging Tiansheng's product advantages and localized service support, quickly opened up the local industrial and wind power markets, achieving a steady increase in annual sales. We sincerely invite partners with local market resources and professional service capabilities to join us and work together to expand the global power equipment market.
