Selecting the right insulating cardboard for transformers involves critical safety parameters that impact performance and longevity. As a leading transformer manufacturer in China, we understand how insulating cardboard properties and material composition directly affect equipment reliability. This guide explores essential technical considerations for professionals evaluating transformer insulation parts processing equipment, from material sourcing to quality control standards.

Understanding Insulating Cardboard Properties

Transformer insulating cardboard serves as a vital component in electrical insulation systems, preventing electrical breakdown and ensuring safe operation. Key properties include dielectric strength, thermal stability, mechanical durability, and moisture resistance. The insulating cardboard material must withstand high voltages, extreme temperatures, and mechanical stresses during transformer operation. At Gaomi Hongxiang Electromechanical Technology, we rigorously test all materials to IEC 60641 standards, ensuring compliance with international safety requirements for power transformers.

Technical Performance Parameters

When evaluating insulating cardboard for transformers, technical specifications become critical decision factors. The dielectric strength typically ranges between 10-30 kV/mm depending on material density and thickness. Thermal class ratings (from Class A to Class H) determine maximum operating temperatures (105°C to 180°C). Our transformer insulation parts processing equipment precisely controls these parameters during manufacturing, producing consistent quality for global customers. Additional parameters include tensile strength (minimum 50 MPa), density (0.8-1.2 g/cm³), and water absorption rates (below 5% after 24 hours immersion).

Procurement Guide for Transformer Manufacturers

Purchasing decisions for transformer insulation parts processing equipment require careful evaluation of multiple factors. Consider the equipment's capability to handle various insulating cardboard materials, including pressboard, laminated wood, and composite materials. Our manufacturing facility in China offers complete solutions from raw material processing to finished insulation components, supporting both standard and custom transformer designs. Key selection criteria should include production capacity (pieces/hour), precision tolerances (±0.1mm), and compatibility with your existing transformer manufacturing processes.

Quality Control and Industry Standards

Stringent quality control measures differentiate premium transformer insulation components. Our production process implements multiple checkpoints, from incoming material inspection to final product testing. All insulating cardboard products meet or exceed IEC 60641, ASTM D202, and GB/T 19264 standards. For international buyers, we provide complete certification packages including material test reports, factory acceptance test certificates, and third-party inspection documents. These quality assurance measures give procurement professionals confidence when sourcing transformer insulation parts processing equipment from China.
