Reliable Electrical Insulation

Designed using premium wood pulp, this pressboard offers outstanding insulation characteristics for a diverse range of electrical applications. Its high flexural strength and controlled compressibility ensure both durability and effective mechanical support, making it a trusted material for the power industry.

Engineered for Performance

With a moisture content capped at 7% and water absorption below 7% after 24 hours, this insulation pressboard maintains performance even in moderately humid environments. The pH value between 6.5 and 8.0 ensures material stability, and the surface finish is smooth and defect-free for optimal compatibility with sensitive equipment.

FAQs of Wood Pulp Insulation Pressboard:

Q: How should Wood Pulp Insulation Pressboard be stored for maximum shelf life?

A: Store the pressboard in a clean, dry area away from direct sunlight. If kept unopened and properly stored, it maintains its properties and shelf life for up to 12 months from the date of manufacture.

Q: What are the key benefits of using this insulation pressboard in electrical systems?

A: This pressboard delivers high flexural strength, stable compressibility, low water absorption, and excellent surface finish. These features enhance electrical insulation performance, ensure structural integrity, and minimize the risk of surface defects, making it suitable for demanding industrial applications.

Q: When does the products performance diminish or its shelf life end?

A: The pressboard retains its full performance for 12 months from the manufacturing date, provided it remains unopened and stored as recommended. Exposure to moisture or sunlight can shorten its effective lifespan.

Q: Where is Wood Pulp Insulation Pressboard typically used?

A: It is widely used in electrical and transformer manufacturing, switchgear insulation, and other applications that require solid electrical isolation and mechanical durability.

Q: What process is followed in producing this high-quality pressboard?

A: The pressboard is made from specially selected wood pulp, processed under stringent controls to ensure uniform moisture, minimal ash content, optimal pH, and a smooth, defect-free finish, meeting international electrical insulation standards.

Q: How does the compressibility and water absorption rate benefit practical usage?

A: With compressibility below 7% at a 2 MPa load and water absorption under 7% after 24 hours immersion, the pressboard reliably maintains its shape and insulation properties even in conditions of mechanical pressure or incidental moisture.
