Vulcanized Paper Insulation Red Steel Paper Gasket

Red steel paper gasket combines the good insulation properties of wood pulp insulating paper and the good dielectric, mechanical toughness, flexibility and resilience of polyester film, and has better thermal stability. Widely applicable to electrical equipment, suitable for slot-to-slot insulation, turn-to-turn insulation and liner insulation of Class B motors.

Red steel paper gasket insulation material is a kind of soft composite material, which is a two-layer insulating paper made of polyester film coated with adhesive and wood pulp insulating paper on one side.

Features of red steel paper gasket insulating paper

The red steel paper gasket insulation material has the function of insulation and anti-interference, high electrical insulation, mechanical strength, softness and elasticity; the red fast paper is especially resistant to acid and alkali corrosion, tear resistance and wear resistance. Moisture insensitive, non-toxic and flame-resistant.

Performance Impact Factors

1. Insulation resistance and resistivity: The smaller the conductivity of the material, the greater its resistance, and the two are in a reciprocal relationship. For the red fast paper insulation material, it is always hoped that the resistivity is as high as possible.

2. Combustion resistance: refers to the ability of the red fast paper insulation material to resist burning when it comes into contact with the flame or prevent it from continuing to burn when it leaves the flame. With the increasing application of red fast paper insulation materials, the requirements for its combustion resistance are more important. People use various means to improve and enhance the burning resistance of red fast paper insulation materials. The higher the burning resistance, the better its safety.

3. Relative permittivity and dielectric loss tangent.

4. Arc resistance: Under the specified test conditions, the ability of the red fast paper insulation material to withstand the arc action along its surface. During the test, AC high voltage and small current are used, and the arc effect generated between the two electrodes by high voltage makes the red The time required to form a conductive layer on the surface of the fast paper insulating material is used to judge the arc resistance of the insulating material; the larger the time value, the better the arc resistance

5. Breakdown voltage and electric strength: Under a certain strong electric field, the red fast paper insulation material is destroyed, and it loses its insulation performance and becomes conductive, which is called breakdown. The voltage at the time of breakdown is called the breakdown voltage (dielectric strength). Electric strength is the quotient of the voltage when a breakdown occurs under specified conditions and the distance between the two electrodes that bear the applied voltage, that is, the breakdown voltage per unit thickness. For red fast paper insulation materials, generally the higher the breakdown voltage and electric strength, the better.

6. Tensile strength: In the tensile test, the maximum tensile stress that the sample bears, it is the most widely used and most representative test for the mechanical performance test of red fast paper insulation materials.
