The Importance of Electrical Cardboard in Transformer Insulation

Electrical cardboard, also known as insulating cardboard, plays a pivotal role in transformer insulation systems. This specialized material is engineered to withstand high voltages, extreme temperatures, and mechanical stress, making it indispensable for transformer cores and other critical components. As a cost-effective transformer insulation parts processing equipment provider, we understand that the quality of insulating materials directly impacts the longevity and performance of power transformers. Our electrical cardboard is manufactured to meet international standards such as IEC 60641 and ASTM D295, ensuring reliable insulation properties for both dry-type and oil-immersed transformers.

Key Properties of High-Quality Insulating Cardboard

When evaluating insulating cardboard for transformers, several critical properties must be considered. Our products exhibit exceptional dielectric strength, typically ranging from 10-15 kV/mm, which is crucial for preventing electrical breakdown. The material's thermal stability allows it to maintain structural integrity at temperatures up to 105°C continuously. Additionally, our electrical cardboard demonstrates:

• Low moisture absorption (less than 5% at 65% RH)
• Excellent mechanical strength (tensile strength > 50 MPa)
• Superior dimensional stability (minimal expansion/contraction)
• Chemical resistance to transformer oil and other coolants

These properties make our insulating cardboard ideal for various transformer insulation components, including barriers, spacers, and end insulation systems.

Manufacturing Process and Quality Control

As a professional transformer insulation parts processing equipment manufacturer in China, we maintain rigorous quality control throughout our production process. Our electrical cardboard undergoes multiple stages of processing:

1. Raw material selection: Only premium cellulose fibers are used
