Paper insulated copper and aluminium conductors are electrical conductors wrapped with multiple layers of specially treated insulating papers such as Mica Tape, Kraft Paper, Thermally Upgraded Paper, and Aramid Paper. These conductors are widely used in high-voltage and high-reliability electrical applications.

Both rectangular and round paper insulated conductors are extensively used in oil-filled power transformers, distribution transformers, dry-type transformers, high-tension motors, and windmill generators.

Insulation Technology & Sustainability

The high-grade insulating papers used are impregnated with insulating oils or resins to enhance their electrical strength, thermal stability, and mechanical performance. Paper insulation provides excellent dielectric properties, helping prevent electrical breakdown under high voltage conditions.

Additionally, paper insulation is considered environmentally sustainable due to its natural biodegradability.

What are Paper Covered Copper / Aluminium Conductors?

Paper covered copper or aluminium conductors are primarily used for winding coils in transformers and heavy electrical equipment. The conductor’s performance depends on:

• Type of insulating paper used
• Number of insulation layers
• Paper thickness and impregnation process

These factors are customized to meet specific electrical, thermal, and mechanical requirements.
