Why do clients in over 100 countries choose TSTY?

The quality of power equipment goes far beyond mere cold statistics in a laboratory. In international engineering projects, the consequences of a transformer failure can be catastrophic—ranging from project delays and skyrocketing costs to major safety accidents and the permanent loss of client trust. Fully aware of this, TSTY Electric—through its collaborations across more than 100 countries—firmly believes that quality is not only a universal language that transcends cultural differences but also the fundamental prerequisite for the successful delivery of international projects.

TSTY is renowned for its rigorous quality system. This is not merely an empty slogan but a commitment woven into every aspect of the production process—from the moment raw materials enter the factory to the final deployment of the equipment.

Strict Source Control Ensures Reliability

Premium Materials Form the Equipment's Core

Equipment performance relies 70% on design and 30% on material selection. Driven by an uncompromising pursuit of quality, TSTY employs a strategic approach to material sourcing. For instance, regarding the transformer core materials that determine no-load loss, we insist on using top-tier grain-oriented silicon steel sheets from Baosteel and WISCO. By utilizing high-magnetic-induction materials with a thickness of 0.23mm, we achieve specific iron loss values ​​significantly lower than the industry average, fundamentally enhancing the product's energy efficiency.

High-End Components Safeguard Stability

As integrated systems, transformers rely heavily on high- and low-voltage components for stable operation. To ensure long-term reliability, we partner with world-renowned brands like Schneider, ABB, and Siemens, as well as leading domestic suppliers such as CHINT and Delixi. We strictly control component quality to prevent potential failures at the source.

In-House Production Bases Ensure Control

To further secure raw material quality, TSTY has invested in its own "Electrical Industrial Park," enabling in-house production and processing of key materials. This "upstream integration" strategy allows TSTY to maintain consistently high product standards, even amidst volatile raw material prices.

Whether it is silicon steel sheets or a single screw, TSTY partners with industry leaders to lay a solid foundation for the equipment's long service life and high-quality performance right from the source. Exquisite Craftsmanship, Unwavering Quality

Micron-level precision for superior performance

The manufacturing process is key to transforming design blueprints into high-quality products. TSTY’s modern factory boasts a 95% automation rate and micron-level machining precision, with manufacturing tolerances strictly controlled within ±0.5mm. This high standard ensures "seamless integration" of all components during assembly, effectively preventing operational noise and potential malfunctions caused by loose structures.

Rigorous anti-corrosion standards for challenging environments

To withstand the humid and salt-laden environments often encountered in overseas projects, we employ a multi-layer anti-corrosion coating process, achieving a coating thickness of 80–120μm. Having passed salt spray tests exceeding 1,000 hours—far surpassing industry standards—our protective measures ensure that transformers remain free from corrosion-related damage throughout their entire lifecycle, even in coastal or harsh environments.

Technology-driven energy efficiency

We integrate state-of-the-art production technologies into our manufacturing, such as cold-pressing silicon steel sheets and utilizing a 7-step, 45-degree fully mitered joint technique during core stacking. These processes reduce no-load losses by 30% and cut additional losses by another 3–5%. Such precision control translates into significant operational cost savings for customers over the equipment's 20-to-30-year service life.

TSTY has obtained multiple international certifications

Robust testing capabilities ensuring flawless products

TSTY operates a top-tier, CNAS-accredited laboratory. Every unit must undergo 48 routine tests and various specialized international tests (such as UL1561 and IEC60076-3) before leaving the factory. These stringent requirements guarantee a 100% pass rate for every piece of equipment bearing the "TSTY" brand.

Comprehensive certification for global market access

We have obtained major international certifications, including ISO9001, IEC, CE, and SGS, with test reports mutually recognized in over 60 countries. This significantly simplifies customs clearance and project acceptance procedures for our customers. Demonstrating strength through data and leading the industry with reliability: our rigorous quality management system delivers outstanding real-world results—TSTY products boast a failure rate in overseas markets that is 90% lower than the industry average. Choosing TSTY means customers gain not only high-quality products but also an assurance that exceeds standard benchmarks.

Quality is not a cost; it is our greatest competitive advantage. When national landmark projects—such as the De Aar Wind Farm in Africa, the Hong Kong-Zhuhai-Macao Bridge, the launch platforms for the Shenzhou spacecraft series, and the Three Gorges Project—choose and place their trust in TSTY equipment, it serves as the ultimate validation of our stringent quality standards.
