Guangxin Insulation
Insulation paper
Premium electrical insulation solutions engineered for high-voltage transformer applications. Delivering excellence in dielectric strength, thermal stability, and mechanical durability.
Precision-Engineered Insulation Systems for Power Transformers
Guangxin engineers premium cellulose-based insulation papers and presspaper for the global electrical sector. We transform base materials through comprehensive secondary processing—creping, coating, laminating, slitting, cuffing, punching, creasing, and tube production—while offering non-cellulosic solutions for high-temperature applications.
Presspaper
High-density electrical pressboard for oil-immersed transformers. Offers excellent dielectric strength, mechanical durability, and oil absorption. Ideal for winding spacers, end blocks, and insulation barriers in power transformers.
DDP
Partially bonded epoxy resin dotted paper for transformer windings. The diamond pattern enables controlled resin flow during curing, improving layer bonding, heat dissipation, and short-circuit resistance.
Kraft Paper
nbleached sulfate pulp insulation paper for oil-filled transformers. Provides good electrical insulation, mechanical strength, and oil impregnation. Widely used for inter-layer insulation and conductor wrapping.
Crepe Paper
Crinkled insulation paper with high stretchability (15-400%). Excellent conformability for irregular shapes and proper oil channel formation. Used for lead insulation and layer separation in transformers.
Crepe Paper Tube
Flexible, pre-formed crepe paper tubing for transformer leads and connections. Provides reliable insulation coverage with easy assembly. Offers superior oil permeability and electrical stress distribution.
