What are TSTY's R&D capabilities like?
TSTY Transformer & Switchgear Company places a high priority on technological innovation and development. The company holds intellectual property rights for all its independently developed products and has secured over 100 authorized national patents for inventions and innovations.
Through relentless research, TSTY has independently resolved critical technical challenges—such as short-circuit withstand capability, localized overheating, partial discharge, and noise issues—ensuring the delivery of safe, reliable, and high-performance products to its customers.
TSTY products comply with global standards
Entering overseas markets requires clearing the hurdle of regulatory compliance first. TSTY has deeply integrated R&D with global standards, establishing comprehensive compliance capabilities. The company holds 158 core patents, including 28 international patents covering major markets such as the EU, the US, and Southeast Asia. Significantly, TSTY has led or participated in the formulation of eight IEC international standards. As the core international standard system for power transformers, IEC 60076 covers comprehensive requirements—including design, manufacturing, and testing—and serves as the mandatory basis for market access in regions like the EU.
This means TSTY’s technical framework aligns with international standards from the very inception of R&D, rather than relying on retroactive certification after product completion. Its products have obtained numerous authoritative international certifications—including IEC, UL, CQC, SGS, CE, and GOST—enabling market access across more than 100 countries and regions worldwide. For international project developers, choosing TSTY means compliance hurdles are resolved upfront, eliminating the need to repeatedly expend time and resources on regulatory approval processes.
Resilience in Extreme Environments
If compliance represents a "soft threshold," extreme environments pose a "hard test." TSTY’s R&D system translates environmental data from 100 countries into design specifications, establishing a library of specialized solutions tailored to various harsh operating conditions:
70°C Deserts in Saudi Arabia: Standard equipment suffers from accelerated insulation aging and drastically reduced lifespans in extreme heat. TSTY transformers utilize Class H (180°C) or higher insulation systems combined with proprietary heat dissipation structures, enabling full-load operation even at an ambient temperature of 50°C. Advanced temperature monitoring technology can reduce equipment failure rates by up to 78% and extend asset lifespans by 30%–40%, resulting in an actual operational life 40% longer than the industry average.
Extreme cold (-40°C) in Russia: Low temperatures often cause insulating oil to solidify and seals to become brittle. TSTY Transformer & Switchgear’s company specialized solution for extreme cold utilizes unique insulating materials and a low-temperature startup design to ensure reliable startup and continuous operation in freezing conditions.
High-salinity coastal environments (e.g., the Philippines): Salt spray corrosion poses a constant threat to metal components and insulation systems. TSTY Transformer & Switchgear employs C5M-grade salt spray protection—featuring AISI 316L stainless steel enclosures and marine-grade anti-corrosion coatings—capable of passing 720-hour neutral salt spray tests and offering a design life of over 15 years.
High-altitude regions (4,500m, e.g., Africa): Reduced air density impairs heat dissipation. Through specialized design and rigorous validation, TSTY Transformer & Switchgear company ensures stable insulation performance even in thin-air environments.
These capabilities have been proven in global projects; TSTY Transformer & Switchgear company’s products are deployed in over 30 African countries, with a cumulative installed capacity exceeding 5,000 MVA. During a smart grid upgrade in Nairobi, Kenya, the company’s dry-type transformers—characterized by low noise and high overload capacity—effectively reduced line losses and earned high praise from the local Ministry of Energy.
Customized Solutions
Another challenge in international projects is slow response times and lengthy customization cycles. Leveraging an environmental database covering 100 countries and a localized service network—including overseas offices in Zambia, Ethiopia, Kazakhstan, Colombia, and Italy—TSTY Transformer & Switchgear delivers rapid customization capabilities.
Taking the African market as an example: by utilizing real-time feedback from local agents regarding Nigeria’s 33kV transmission standards and Kenya’s energy efficiency regulations, TSTY Transformer & Switchgear can produce compliant samples within just 25 days. Underpinning this speed are CNAS-accredited laboratories, 5G smart production lines, and an end-to-end digital-intelligent system—resulting in a 50% increase in production efficiency and a 99.9% pass rate.
