Custom Oil-Immersed Transformers & On-Load Tap Changers Shipped for Critical Power Infrastructure Upgrade 

ZHEJIANG, CHINA | [Current Date] — Zhejiang Tenrony Electric Co., Ltd. (Tenrony Electric) has successfully dispatched a full order of CE-certified oil-immersed transformers and intelligent on-load tap changers (OLTC) to a key power infrastructure project in Laos. The shipment includes multiple units across critical capacities: 8000kVA, 2000kVA, 1000kVA, and 500kVA, engineered to enhance grid stability and support industrial expansion in northern Laos.

Zero-Defect Quality Assurance

Every unit underwent Tenrony Electric’s rigorous 72-hour validation protocol:
Precision winding verification (≤0.1% tolerance)
Vacuum oil-filling & hermetic sealing tests
Full-load loss, temperature rise, partial discharge, and dielectric strength trials
Final audit against CE marking requirements and IEC 60076 international standards
All equipment cleared certification with documented test reports and carries Tenrony’s comprehensive warranty—proving reliability before departure.

Engineered for Tropical Resilience

Tailored for Laos’ high-temperature, high-humidity environment:
8000kVA main transformer: S11-M fully sealed design with 30% enhanced short-circuit withstand capability; operational range: -25°C to +55°C
Smart OLTC units: ±15% dynamic voltage regulation with <3-second response time for stable power delivery to mines and industrial zones
Corrosion-resistant coatings, moisture-proof breathers, and tropicalized insulation systems ensure decades of trouble-free service
