Electrical Presspan Board is a premium-quality insulating material manufactured from 100% high-purity cellulose fibers through a specialized compression and drying process. It is designed to meet the demanding electrical and mechanical requirements of power distribution systems, oil-filled transformers, high-voltage motors, generators, and switchgear. The board’s uniform structure and high mechanical strength make it an excellent choice for insulating components that must perform reliably in harsh electrical and thermal environments.

Presspan board serves as a critical insulation barrier in transformer windings, spacers, cylinders, and structural parts. It provides consistent electrical insulation performance, ensuring long-term reliability and safety in applications that operate under high voltage and elevated temperatures. Its compatibility with standard transformer oils and synthetic ester fluids makes it suitable for use in both conventional and eco-friendly electrical systems.

The dense, smooth surface of Electrical Presspan Board ensures precise fabrication, reduced dust generation, and excellent dimensional stability. It is resistant to deformation, cracking, and delamination, even under mechanical stress or thermal cycling. Its oil-absorbing properties enhance dielectric strength over time, making it ideal for prolonged use in immersed environments.

 Performance Advantages:

  • Exceptional dielectric properties ensure effective high-voltage insulation

  • High compressive and mechanical strength for structural reliability

  • Low moisture content and excellent oil absorption for increased lifespan

  • Resistant to thermal degradation and mechanical stress

  • Can be cut, punched, milled, or molded into complex shapes without compromising integrity

  • Stable electrical properties even under oil-immersed or humid operating conditions

Technical Specifications:

  • Composition: 100% cellulose fiber (press-compressed)

  • Thickness range: 0.5 mm to 50 mm

  • Dielectric strength: ≥ 6–10 kV/mm (varies by grade and thickness)

  • Density: 0.9–1.3 g/cm³

  • Thermal classification: Class A (105°C continuous operation)

  • Moisture content: ≤ 8%

  • Oil compatibility: Compatible with mineral oils and synthetic esters

  • Industry standards: IEC 60641, ASTM D3300, IS 1576

Common Applications:

  • Transformer core and coil insulation

  • Oil-immersed transformer spacers, barriers, and support structures

  • Insulating cylinders and layers in power and distribution transformers

  • Interlayer insulation in windings and terminals

  • Structural dielectric components in switchgear and high-voltage equipment

  • Motor and generator slot insulation and wrapping
