High-Dielectric Electrical Transformer Insulation Paper Rolls in Bangladesh

At Trafo BD, we supply high-purity Transformer Electrical Insulation Kraft Paper Rolls (ট্রান্সফরমার ইনসুলেটিং ক্রাফট পেপার) essential for layer-to-layer insulation, conductor wrapping, and phase barriers inside distribution and power transformers. Manufactured under strict quality control standards, our presspaper features exceptional chemical purity, uniform thickness, and rapid mineral oil impregnability to withstand high thermal and electrical breakdown stresses.

Whether you are assembling new distribution transformers or running coil rewinding repair shops across Dhaka, Chattogram, Gazipur, Narayanganj, or Bogura, our insulation paper rolls ensure long service life and zero moisture contamination.

Key Features & Benefits for Local Manufacturers:

1. High Tensile & Tear Strength: Easily withstands high-tension automated coil winding machines without tearing or stretching out of shape.
2. Excellent Oil Impregnation: Rapidly absorbs transformer oil to eliminate air pockets, micro-voids, and partial discharge risks.
3. Purity & Zero Ash Content: Free from metallic particles, conductive impurities, or pinholes that cause premature dielectric breakdown.
4. Moisture-Proof Packaging: Delivered in tightly sealed moisture-barrier rolls to preserve dryness during transport and storage across humid factory environments in Bangladesh.

Applications in Transformer Assembly:

• Inter-layer Winding Insulation: Separates copper/aluminum conductor layers in HV and LV coils.
• Lead Wire & Busbar Wrapping: Wraps internal copper leads and connections for thermal protection.
• Core & Bobbin Barrier Lining: Provides safe clearance between the magnetic core laminations and coil windings.
