Transformer Insulation Crepe Paper :

We are manufacturing a wide range of the Insulation Crepe Paper used in transformers that are specially designed for the electrical industries. These are offered in the different sizes and dimension. These are fire resistant and durable in service and have good flexibility. On being highly qualitative, these are superior in their functionality and performance.

Superior Flexibility for Precise Coil Wrapping

This crepe papers high elongation (over 12%) and adaptable thickness (0.080.50 mm) allow for easy conformation to intricate coil shapes in a variety of transformer designs. The uniform creped texture enhances stretchability without sacrificing mechanical or electrical performance, ensuring a secure and snug wrap every time.

Engineered for Electrical and Thermal Safety

With a dielectric strength of at least 8 kV/mm and heat resistance up to 105C (Class A), this insulation paper safeguards transformer coils against voltage stress and temperature fluctuations. The high-density construction and low thermal conductivity ( 0.04 W/mK) ensure reliable operation and minimal heat buildup.

Optimal Oil Absorption for Enhanced Insulation Performance

Designed with high oil absorption, the crepe paper efficiently interacts with transformer oils, filling micro-voids and enhancing dielectric properties. This feature significantly improves insulation reliability and operational longevity within transformer systems.

FAQs of Transformer Insulation Crepe Paper:

Q: How should Transformer Insulation Crepe Paper be stored for optimal performance?

A: Store crepe paper in a dry, well-ventilated area away from direct sunlight. This prevents moisture absorption and preserves dielectric strength and mechanical properties, with an effective shelf life of up to 18 months.

Q: What type of crepe ratio does this paper offer, and why is it important?

A: The crepe paper provides a crepe ratio of 1.5 to 3.5 folds, which ensures high flexibility for efficient wrapping around coils. This ratio improves mechanical strength and allows the paper to conform to complex shapes without tearing.

Q: Where is this insulation crepe paper typically used?

A: It is primarily used as a wrapping and insulation material for coils in power and distribution transformers, where high electrical, mechanical, and oil absorption properties are essential.

Q: What benefits does the high oil absorption rate provide in transformer applications?

A: A high oil absorption rate helps the paper fill gaps and prevent electrical breakdowns by improving the dielectric insulation between conducting components, thereby extending the service life of transformers.

Q: How is the crepe paper manufactured to ensure purity and consistency?

A: The paper is mechanically creped from high-purity base paper made of 100% cellulose, resulting in a consistent texture and minimal ash, moisture, and acid content for maximum insulation performance.

Q: When should this insulation crepe paper be replaced or inspected in transformers?

A: Routine inspections should be aligned with transformer maintenance schedules. Replace the paper if it shows signs of mechanical damage, loss of flexibility, or contamination, typically after 18 months or as specified by quality checks.

Q: What is the typical process for using this crepe paper in transformer coil wrapping?

A: The paper, available in custom roll lengths and widths up to 1000 mm, is wrapped directly onto the coil conductors either manually or by machine, followed by impregnation with oil to maximize its dielectric and insulation efficiency.
