SILIGAINE 15C5 – direct replacement for OsKs cable sleeves

Comparison of SILIGAINE 15C5 and SILICONE INSULATING SLEEVES (OSKS): Which is best for your applications?

Nowadays, choosing the right insulating material is crucial in many areas of the electrical industry. For customers who need reliable wire insulation, two popular options, SILIGAINE 15C5 and SILICONE INSULATING SLEEVES (OSKS), offer many advantages. In this article, we'll take a closer look at these two products, comparing their features, uses, and benefits to help you choose the right option.



  • Continuous operation temperature: -60°C to +250°C
  • Good resistance to moisture, ozone and UV rays
  • Good resistance to chemical environments
  • Dielectric strength: >7 kV
  • Halogen-free design

SILIGAINE 15C5 is distinguished by a wide range of operating temperatures, which makes it an excellent choice for applications in extreme conditions. Resistance to moisture, ozone and UV rays make it durable in difficult weather conditions. Furthermore, dielectric strength above 7 kV is excellent for applications requiring electrical insulation.

Applications and industries where it is popular:

  • Engines
  • Transformers
  • Alternators
  • Class H and C generators
  • Devices operating at high temperatures up to 250°C

Benefits of using SILIGAINE 15C5:

  • Exceptional flexibility
  • Fire safety confirmed by the VW-1 test in accordance with the UL 1441 standard
  • Can be used with most class H impregnation varnishes

Examples of applications in practice:

  • Insulation of wires in transformers
  • Cable protection in generators


OSKS Product Specifications:

  • Continuous operation temperature: -70°C to +180°C
  • Resistance to external factors
  • Dielectric strength: ≥ 4.3 kV
  • Halogen-free design

SILICONE INSULATING SHIRTS (OSKS) they also offer a wide operating temperature range, although slightly lower than SILIGAINE 15C5. However, they are still an excellent option for many applications, especially in terms of their resistance to external factors and dielectric strength.

Applications and industries where it is popular:

  • Electric motors
  • Welding machines
  • Transformers
  • Lighting
  • Household appliances (household appliances)

Benefits of using OSKS:

  • Great flexibility
  • Mechanical resistance
  • Resistance to soldering heat
  • Resistance to transformer oils

Examples of applications in practice:

  • Insulation of wires in engines
  • Cable protection in welding machines

III. Comparison: SILIGAINE 15C5 vs. OSKS

To help you choose between SILIGAINE 15C5 and OSKS, let's analyze the key aspects of both products:

Operating temperature: SILIGAINE 15C5 offers a wider operating temperature range from -60°C to +250°C, while OSKS operates in the range from -70°C to +180° C If you need insulation at very low or very high temperatures,SILIGAINE 15C5may be a better choice.

Resistance to external factors: Both SILIGAINE 15C5 and OSKS are resistant to external factors, but SILIGAINE 15C5 offers additional protection against UV rays, which may be important in some applications.

Dielectric strength: SILIGAINE 15C5 has a higher dielectric strength (>7 kV), which is important in applications requiring electrical insulation. OSKS offers a dielectric strength of ≥ 4.3 kV.

Halogen-free design: BothSILIGAINE 15C5andOSKSare halogen-free, which is advantageous from an environmental and safety perspective.

Applications: SILIGAINE 15C5 is often used in equipment operating at very high temperatures, such as Class H and C generators. OSKS is popular in electric motors and welding machines.

IV. Which Product Should You Choose?

Ultimately, the choice betweenSILIGAINE 15C5andOSKSwill depend on individual needs and applications. If you work in extreme temperature conditions or need higher dielectric strength,SILIGAINE 15C5may be a better choice. However, if you need flexible insulation for electric motors or welding machines,OSKSmay be more suitable.

It is always recommended to consult with an expert or supplier to determine exactly which product best meets your specific needs. Ultimately, both products offer excellent wire insulation and will help maintain safety and efficiency in your electrical applications.

V. Summary

Both products, SILIGAINE 15C5 andOSKS, have their unique advantages and applications. The choice depends on specific requirements and operating conditions. Therefore, it is worth carefully understanding your needs and consulting with an expert to make the best decision regarding wire insulation for your electrical projects.
