Our Insulation Phenolic Cotton Fabric Laminate Bakelite Rods are designed to deliver exceptional mechanical and electrical performance in demanding applications. With a bending strength of at least 118 MPa and tensile strength of 78 MPa, these rods offer reliable durability and resistance to stress in various environments. You'll appreciate their high insulation resistance, which ensures safe operation under both normal and water-impregnated conditions, with values of at least 1.0×10^8 Ω.
The breakdown voltage, at 10 kV (20±5°C), provides excellent protection against electrical failures, making these rods ideal for use in transformer applications. With a density range of 1.25–1.40 g/cm³, they combine strength and lightweight properties, ensuring long-lasting performance in electrical systems. Additionally, these rods have a thermal resistance rating of Class E, allowing them to withstand high temperatures.
Available in natural and black colors, our Bakelite rods are an excellent choice for insulation needs, offering both functionality and safety with flame retardancy (FV0).
