Cable Component Non-Flammable Fiberglass Separator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication cables face issues with crosstalk interference due to electromagnetic coupling and require flame retardant materials that are often toxic and expensive, such as halogenated fluoropolymers, which also pose risks during burns.
Innovation Solution
Incorporating non-flammable materials like flexible fiberglass portions into cable separators to reduce the fuel load and replace toxic halogenated materials, maintaining flexibility and improving burn performance while meeting industry standards for flame resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flame retardant materials like fluoropolymers are used in cable separators, then burn resistance is improved, but toxic halogen emissions and melting/dripping occur during combustion
Solution Approach 1:
The patent combines non-flammable fiberglass material with flame retardant polymer material to create a composite separator. The fiberglass provides structural integrity and non-flammability, while the polymer matrix provides flame retardancy. This composite approach eliminates toxic halogen emissions by replacing halogenated fluoropolymers with halogen-free polymer matrices filled with fiberglass reinforcement.
2Reliability
If halogenated fluoropolymers are used for flame retardancy, then burn test requirements are met, but material cost increases due to high demand
Solution Approach 1:
The patent substitutes expensive halogenated fluoropolymers with more economical halogen-free polymer matrices combined with fiberglass reinforcement. This replacement reduces material costs while maintaining compliance with burn test requirements through the synergistic flame retardant properties of the composite structure.
3Reliability
If more insulation material is used in separators, then flame retardancy is improved, but fuel load increases worsening burn performance
Solution Approach 1:
The patent incorporates fiberglass reinforcement within the polymer matrix, creating a composite structure with reduced overall material volume. The fiberglass provides structural support and flame resistance, allowing reduction of the polymer insulation material volume while maintaining or improving flame retardancy performance and reducing fuel load.

AI summary
A cable component that comprises a main body where at least a part of the main body is formed of an insulation material, and at least one non-flammable portion is disposed in the insulation material of the main body. The non-flammable portion forms at least about 25% by volume of the cable component, is flexible, and reduces the amount of the insulation material of the main body, thereby reducing the fuel load in the cable component.
