Electrical Laminated Wood Board is a composite material produced from premium birch wood through processes including steaming, rotary cutting, and drying. The processed veneer is coated with specialized insulating adhesive and manufactured via high-temperature, high-pressure techniques. Widely used in distribution transformers, instrument transformers, and reactors as insulation liners and structural supports, it boasts moderate density, high mechanical strength, vacuum-drying adaptability, and ease of machining. When properly insulated, it can withstand long-term exposure to 105℃ transformer oil. In oil-immersed transformers, this material is extensively employed to manufacture upper/lower pressure plates, lead supports, and yoke spacers. For instrument transformers, it replaces steel plates, phenolic paper/cloth boards, and epoxy glass fiber cloth boards in critical components, effectively reducing both the transformer's weight and material costs.
