What Is Electrical Insulation Kraft Paper?

Electrical insulation kraft paper is a specially processed cellulose insulation paper designed for electrical applications requiring dielectric strength, mechanical flexibility and long-term stability.

Compared with ordinary packaging kraft paper, electrical insulation kraft paper is manufactured with higher purity and stricter quality control to ensure suitability for electrical insulation systems.

Material: 100% purity sulfate insulating wood pulp

Forms: Available in various thicknesses (e.g., 50-200 um) and customized widths

Technical Advantages:

• Flexibility & Conformability: Wraps smoothly and securely around conductors of various shapes, creating a uniform insulating layer without gaps.

• Superior Dielectric Strength: Delivers excellent electrical insulation, effectively isolating conductors and preventing short circuits, even under high-voltage stress.

• High Thermal Stability: Formulated to withstand the sustained heat generated within operating cables and during load cycles, ensuring long-term reliability.

• Optimal Porosity & Absorption: Its controlled density allows for thorough and rapid impregnation with insulating oils, compounds, or resins, filling the paper’s structure to eliminate air pockets and form a homogeneous, void-free insulation system.

• Low Conductivity & Non-Corrosive: Chemically pure and free from conductive impurities or corrosive elements, it protects copper and aluminum conductors from degradation.

  
  

Applications of Electrical Insulation Kraft Cable Paper:

1. Oil-Impregnated Paper-Insulated (PILC) Power Cables: For medium and high-voltage underground and submarine power transmission and distribution.

2. Mass-Impregnated Non-Draining (MIND) Cables.

3. Pipe-Type Cables.

4. Insulation for pilot wires, control cables, and specialty instrumentation cables.
