What is an insulating cartogen

Cartogens are made up of highly compacted cellulose fibers. During production, the fibers are treated with thermosetting resins which give the material mechanical strength, chemical resistance and dimensional stability.

Insulating cartogens are characterized by the following features:

  • Excellent dielectric properties
  • Very low hygroscopicity
  • Good mechanical strength
  • Ease of machining
  • Low costs

Thanks to these properties, cartogens are widely used as electrical insulators in transformers, switches, electrical equipment and many other fields.

Uses of insulating cartogens

Cartogens are used to create a wide range of products for electrical insulation:

  • Corrugated tubes and sleeves for insulating electrical cables
  • Barriers and separators for electrical machinery and equipment
  • Bushings for the passage of conductors through metal walls
  • Supports and bases for windings of electrical machines
  • High temperature insulators up to 155°C in class F

Thanks to their versatility, cartogens provide an efficient and economical solution for a wide variety of industrial applications.

Benefits of insulating cartogens

The use of cartogens as electrical insulators offers several benefits:

  • Excellent dielectric properties: cartogens have very good dielectric strength, volume resistivity and dissipation factor. This allows reliable and durable insulation.
  • Very low hygroscopicity: moisture absorption is very limited thanks to hydrophobic resin treatments. This prevents degradation of insulating properties.
  • Good mechanical strength: cartogens have decent tensile, compressive and flexural strength. They are therefore suitable for withstanding stresses.
  • Ease of machining: cartogens lend themselves well to cutting, drilling, embossing, bending. They can be shaped in various forms.
  • Low costs: compared to other insulating materials, cartogens have significantly lower costs while providing adequate performance.

Thanks to these advantages, insulating cartogens are often the ideal choice for medium/low voltage electrical and electromechanical applications.

Conclusions on insulating cartogens

Cartogens are versatile and economical dielectric materials obtained from paper processing and impregnated with thermosetting resins.

Their excellent insulating and mechanical properties make them the ideal choice for manufacturing tubes, barriers, supports and other components for electrical insulation of machinery and equipment.

Thanks to easy machining, low costs and high performance, insulating cartogens are often the most advantageous solution for industrial, electrical and civil applications at medium and low voltages.
