Performance and manufacturer introduction of electrical insulation paper

1. insulation paper

Insulation paper, also known as transformer insulation paper or electrical insulation paper, is a type of paper used in electrical applications to provide insulation between conductive components. It is a critical component in transformers and other electrical devices where electrical insulation is essential. Insulation paper is designed to withstand high electrical voltages and temperatures while preventing electrical breakdown and ensuring the safety and reliability of the equipment.

2. Electrical insulation properties.

Presspahn paper is commonly used for the electrical insulation of transformers and certain motors and equipment. It is suitable for applications up to Class A (105°C). The following table provides electrical strength (in oil) ratings:

Thickness Breakdown voltage
0.1 mm - 0.15 mm ≥12kV/mm
0.15mm - 0.4mm ≥11kV/mm
0.5 mm ≥35kV/mm
Presspahn paper applications.
Presspahn is most commonly used as a flexible electrical insulation for transformers. It is also sometimes used for low-voltage, low-temperature motors, and various other electronic devices.

3.Key characteristics of insulation paper include:

1. Dielectric Strength: Insulation paper must have high dielectric strength to withstand the electric field without breaking down. This property is crucial in preventing electrical arcing and short circuits.

2. Thermal Stability: Insulation paper is often exposed to elevated temperatures within electrical equipment. Therefore, it needs to exhibit thermal stability to maintain its structural integrity and insulating properties at high temperatures.

3. Mechanical Strength: The paper must have sufficient mechanical strength to withstand the mechanical stresses and pressures within the equipment. It should resist tearing or puncturing during installation and operation.

4. Chemical Compatibility: Insulation paper should be chemically compatible with the surrounding materials, including insulating oils used in transformers. This ensures that the paper does not degrade over time due to chemical reactions.

5. Low Moisture Absorption: Excessive moisture absorption can compromise the insulating properties of the paper. Insulation paper is often treated to have low moisture absorption characteristics.

6. Thickness Variability: Insulation paper is available in various thicknesses to meet the specific insulation requirements of different applications. Thicker paper is often used in high-voltage applications.

4.Common types of insulation paper used in transformers and electrical equipment include:

• Kraft Paper: A strong, durable paper made from sulfate pulp, often used in transformer windings.

• Pressboard: A thicker, denser paperboard used in transformer insulation for its high dielectric strength.

• Nomex: A synthetic aramid paper known for its thermal stability and flame resistance, used in high-temperature applications.

• Mylar: A polyester film often used as a dielectric material in capacitors, transformers, and other electrical devices.

The choice of insulation paper depends on the specific requirements of the electrical application, including voltage levels, operating temperatures, and mechanical stresses. Proper selection and application of insulation paper are crucial for ensuring the reliable and safe operation of electrical equipment.
