Red Steel Electrical Insulating Paper Sheet /Board for Transformer
1.Description: Red steel paper is a highly rigid processing paper. Finished products are flat, reel, tube and so on. Paper is hard. Paper is hard. It has excellent elasticity, wear resistance, corrosion resistance, heat resistance, mechanical strength, insulation and mechanical processing and forming properties. Red steel paper is made of steel paper base paper with cotton and wood mixed pulp and treated by zinc chloride special process. The paper has high tightness, high tensile strength, good smoothness, fine and smooth surface, no fading, no color difference, low water absorption, low moisture regain, high weatherability, heat resistance and light resistance.
2.Specifications 1). High mechanical and tensile strength 2). Easily bendable and perforated without any cracking 3). Exceptionally light weight, about half the weight of aluminum 4).
