In the world of electrical insulation materials, the Phenolic Cotton Cloth Laminated Sheet is recognized for its excellent mechanical durability, insulation reliability, and long service life. According to market research, the global electrical insulation materials market is projected to exceed USD 14.3 billion by 2030, with strong demand from motors, transformers, and switchgear industries. Within this trend, phenolic cotton cloth boards remain one of the most trusted materials thanks to their cost-effectiveness and stability.
Phenolic Cotton Cloth Board is produced by impregnating cotton fabric with phenolic resin, then hot-pressing into rigid sheets. This process creates a high strength insulation sheet with a balance of mechanical toughness and electrical safety, making it widely used as a transformer insulation board material and in various industrial applications.
Key Features and Advantages (Phenolic Cotton Cloth Board Properties)
• High Mechanical Strength – Excellent load-bearing capacity, suitable for gears, bushings, and structural parts.
• Excellent Heat Resistance – Stable performance up to ≤120°C continuous working temperature, with short-term tolerance even higher.
• Outstanding Electrical Insulation – Volume resistivity >10^12 Ω·cm, ensuring reliable insulation in switchgear and transformers.
• Wear Resistance & Lightweight – A reliable industrial laminated sheet for mechanical parts, replacing metal to reduce weight and friction.
• Good Machinability – Can be easily cut, drilled, and processed into custom insulation components.
Motors and Transformers – Used as insulation spacers, support boards, and transformer coil supports.
Switchgear & Electrical Equipment – Provides stable electrical insulation boards for high-voltage and medium-voltage systems.
Industrial Machinery – Applied in gears, bearings, washers, and friction-resistant parts.
Transportation & Aerospace – Lightweight yet strong, replacing metal mechanical parts for energy efficiency.
Industry Insight: Studies show that phenolic laminated sheets reduce equipment failure rates by up to 18% compared with conventional insulation boards, directly lowering maintenance costs.
