Premium Transformer Permawood (Densified Laminated Wood) in Bangladesh
At Trafo BD, we supply high-grade Transformer Permawood Sheets and Blocks (ট্রান্সফরমার পারমাউড), specifically manufactured to meet the rigorous mechanical and dielectric requirements of modern transformer design. Made from selected beech or birch wood veneers impregnated with thermosetting synthetic resin under extreme heat and pressure, Permawood provides exceptional mechanical load-bearing capacity combined with reliable electrical insulation.
It acts as a lightweight, non-magnetic alternative to structural steel parts inside high-voltage transformers, eliminating eddy current losses and maintaining long-term stability in transformer oil.
Primary Applications in Bangladesh Transformer Manufacturing:
- Core Clamping Rings & Pressure Plates: Holds core-coil assemblies tightly together to withstand severe electrodynamic forces during short circuits.
- Lead Brackets & Structural Supports: Securely holds internal copper leads, busbars, and tap-changer connections.
- Coil End-Caps & Spacers: Acts as heavy-duty load-bearing support blocks at the top and bottom of high-voltage winding coils.
- Step-up & Distribution Substation Transformers: Essential structural component for grid-level power transformers and industrial distribution units.
Why Source Permawood from Trafo BD?
- Superior Mechanical Strength: Offers high flexural and compressive strength without deforming under continuous mechanical pressure.
- High Oil Compatibility: Easily vacuum-dried and oil-impregnated, ensuring long lifespan without contaminating dielectric transformer oil.
- Machinability: Easily CNC-machined, drilled, or turned into custom technical shapes, clamping rings, and specialized blocks.
- Direct BD Wholesale Pricing: Competitive per kg/sheet pricing for local transformer OEM factories, repair shops, and substation contractors in Dhaka, Chattogram, Gazipur, Narayanganj, and Khulna.
