FAQ

Q1: How do I choose the appropriate thickness of kraft paper insulation?

A1: The thickness selection depends primarily on the operating voltage level and application scenario. Generally, low-voltage equipment uses a 0.08-0.13mm gauge, medium-voltage equipment uses a 0.15-0.25mm gauge, and high-voltage equipment requires a 0.3mm or larger gauge. Our technical team can provide professional selection advice.

Q2: What is the shelf life of kraft paper insulation?

A2: Under appropriate storage conditions (temperature 20-25°C, relative humidity 50-65%), the product shelf life is typically 24 months. It is recommended to avoid direct sunlight and humid environments.

Q3: Do you offer customized services?

A3: Yes, we can provide customized products with different thicknesses, widths, mechanical strengths, and dielectric properties according to customer requirements. We can also perform special impregnation treatments on our products.
