Customer Feedback

Kim Mothea

– from South Africa

Tengyiโ€™s dry-type transformers thrive in our coal minesโ€”zero fire risks despite constant coal dust and methane exposure. Survived 3+ years of 24/7 use without a single overheating incident. Energy efficiency cut our costs by 18%. Maintenance? Almost none. Just wipe down monthly. Worth every penny.

Briandale Vita

– from Philippines

Replaced outdated units with Tengyiโ€™s. No oil changes, no messy spills. Just annual inspections. Lasted 2 years in humid, salt-rich coastal minesโ€”no corrosion. Power output stayed steady even during peak loads. No short circuits despite gritty air.
