Premium DPC Paper Tapes for Transformer Conductor Insulation in Bangladesh
At Trafo BD, we supply high-dielectric DPC (Double Paper Covered) Insulation Paper Slit Tapes (ডিপিসি পেপার রোল) engineered for continuous, tear-free wrapping around copper and aluminum winding conductors. Manufactured under strict quality standards, these narrow slit paper tapes feature uniform thickness, high stretch resistance, and zero metallic impurities, ensuring smooth operation on horizontal and vertical paper covering machines across factory workshops in Dhaka, Chattogram, Bogura, and Gazipur.
When immersed in transformer oil, our DPC paper rapidly absorbs dielectric fluid to form a tough insulation layer around winding conductors, preventing turn-to-turn short circuits under high mechanical and electrical load stress.
Available Width Variants (In Stock):
- 0.13 mm × 8 mm (Ideal for fine round wire & small rectangular strip wrapping)
- 0.13 mm × 12 mm (Standard size for LT/HT copper winding wire)
- 0.13 mm × 14 mm (Popular for medium rectangular aluminum & copper strip DPC covering)
- 0.13 mm × 16 mm (Designed for heavy conductor strip wrapping)
- 0.13 mm × 25 mm (Ideal for wide copper busbars, lead wires & core/coil layer wrapping)
Key Benefits for Local Transformer Manufacturers & Rewinding Shops:
- Burr-Free Precision Slitting: Smooth, clean edges ensure the tape runs smoothly through machine spinners without fraying, tearing, or jamming.
- High Tensile Endurance: Withstands high winding tension without breaking during multi-layer double paper wrapping processes.
- Porous Oil Impregnation: Quickly absorbs transformer mineral oil, leaving zero trapped air bubbles, micro-voids, or partial discharge risks.
- Chemical Purity: Neutral pH value with zero conductive particles protects copper and aluminum conductors from oxidation and chemical degradation over decades of continuous operation.
Common Applications:
- Wrapping round and rectangular copper winding wires.
- Wrapping aluminum strips for distribution transformer LT/HT coils.
- Inter-turn insulation for power transformer coil winding.
- Taping lead wires, internal busbars, and tap changer connections.
