Rooted in the power industry
Every great company starts small. Ours began in Zhenjiang — with just three people, limited resources, and a challenging market environment.
Instead of focusing on constraints, we focused on execution. Step by step, we overcame technical barriers, strengthened our capabilities, and built a solid foundation for growth.
Today, Xintai is a trusted partner to leading transformer manufacturers worldwide. We operate fully integrated production, covering both paper and wood insulation materials, supported by multiple manufacturing bases and strictly controlled production environments.
Our commitment is simple: consistent quality and reliable performance. Through controlled temperature and humidity conditions, we ensure stability across every product we deliver.
We understand that high-voltage and ultra-high voltage applications demand absolute reliability. That is why we invest 4% of our annual revenue into R&D, continuously improving our solutions across voltage levels from 20kV to 1000kV.
Our performance speaks for itself:
- 99% first-pass qualification rate
- 95% on-time delivery
We manufacture:
- Low & High Density Pressboard
- Laminated PressBoard
- Customized Insulation Paper & Wood Component
- Epoxy Insulation Component
- Complete Insulation Kit
More importantly, we bring the same mindset that built our company — practical, disciplined, and results-driven.
We do more than supply insulation materials. We support our customers throughout the entire project lifecycle, from engineering collaboration to long-term performance.
From a team of three to serving global clients, one thing has never changed: our commitment to reliability, partnership, and continuous improvement.
We look forward to working with you.
