LYLC-492
Fire-safe, biodegradable dielectric fluid. The cost-effective alternative to Europe's leading synthetic ester brands.
How Does LYLC-492 Compare?
10–20× More Water Tolerance Than Mineral Oil
Moisture is the #1 enemy of transformer insulation. LYLC-492 absorbs water from cellulose paper, extending insulation life and reducing maintenance costs.
Built for Critical Infrastructure
Technical Specifications
Complete performance data tested per IEC 61099:2010. LYLC-492 meets or exceeds all standard requirements.
