Insulation Pressboard Strips For Transformer

Insulation pressboard strips are made from high quality pressboard G4 grade. Insulation pressboard strips are precision-engineered components designed to provide critical structural support and reliable cooling channels within oil-immersed power and distribution transformers. Manufactured by bonding high-density transformer board sticks onto insulating paper or single-coated diamond dotted paper, they form the essential oil ducts in layer and strip windings.

 Insulation class: A (105 °C)

 Material: 100% sulphate wood pulp

 Color: Natural-color

Low shrinkage, fiber-free surface

Advantages & Characteristics of Insulation Pressboard Strips:

• Superior Mechanical Strength: Exhibits exceptionally high compressive strength, significantly outperforming older corrugated pressboard technology, ensuring dimensional stability under heavy electromagnetic forces.

• Excellent Dielectric Properties: Provides high electric strength, guaranteeing reliable insulation integrity throughout the transformer's operational life.

• Precision Manufacturing: Features accurate and consistent dimensions, facilitating easy and precise installation during the transformer manufacturing process.

• Optimized Oil Impregnation: Possesses excellent compatibility with transformer oil, allowing for rapid and thorough impregnation which enhances cooling efficiency and dielectric performance.

• High-Temperature Stability: Suitable for use in high-temperature operating conditions, contributing to improved circuit strength and overall system reliability.
