Insulation Structure Overview
Epoxy Resin Encapsulation Technology: Patented Cast resin type transformer process fully encapsulates coils and windings via vacuum pressure impregnation (VPI), forming a high-mechanical-strength insulation transformer layer resistant to moisture and dust.
Multi-Layer Insulation Protection:
Inner layer: Nanoscale resin-soaked fiber paper.
Middle layer: Dielectric barrier material resistant to corona effects.
Outer layer: High-fire-retardant epoxy coating.
This triple-layer design elevates dielectric breakdown voltage to 20kV/mm for long-term stable performance.
High-Temperature Curing Process:
Cured at 180℃, the resin matrix achieves dense molecular structure, enhancing crack resistance by 50% and boosting dielectric properties of the Cast resin dry type transformer.
Partial Discharge Suppression:
Optimized end-field distribution and conductive shielding layers keep partial discharge below 5pC, significantly reducing insulation aging risks.
Environmental & Reliability Assurance:
Lead-free epoxy resin complies with RoHS standards, and the insulation structure passes 1.2/50μs lightning impulse tests for rugged reliability in harsh conditions.
