Product Description
Insulation pressboard Presspaper Insulated Paper for transformer
Insulation grade: B class Thickness: 0.2-60mm Dimension: 1000×2000mm, 1600×3200mm, 2200x4400mm Customization: Processing based on Drawings
Electrical insulation pressboard is made of high-purity 100% sulphate wood pulp processed by high-pressure processing. This product has high chemical purity and high mechanical strength. After immersion, it has both mechanical and electrical properties. Electrical insulation pressboard is widely used in oil-immersed transformers and reactors, capacitors, switches, etc.
The production of CNC machined components as per drawings of our customers is our speciality. We utilize versatile modern CNC milling machines, special engraving machines and processing centers.
