Hybrid Ceramic-Polymer Insulator for Thermal and Mechanical Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional insulators face mechanical stress, thermal loading, and material fatigue due to environmental factors, particularly in harsh climates or high seismic activity, leading to performance degradation and structural failure.
Innovation Solution
A hybrid insulator design combining a ceramic core with a polymer shell, where the core provides increased mechanical rigidity and thermal resistance, while the shell offers improved flexibility and electrical insulation, with a threaded engagement for secure pin fixation and a concave saddle for line support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If ceramic insulators are used, then thermal resistance and mechanical rigidity are improved, but susceptibility to mechanical damage increases
Solution Approach 1:
The insulator combines a ceramic core with a polymer shell to create a composite structure that integrates the thermal resistance of ceramic materials with the mechanical flexibility and damage resistance of polymer materials, resolving the contradiction between thermal performance and mechanical durability
2Strength
If polymer insulators are used, then mechanical flexibility and electrical insulation are improved, but susceptibility to thermal damage increases
Solution Approach 1:
The hybrid insulator structure places the polymer material as an outer shell surrounding a ceramic core, allowing the polymer to provide mechanical flexibility and electrical insulation while the ceramic core provides thermal resistance, thus resolving the contradiction between mechanical flexibility and thermal damage resistance
3Ease of manufacture
If traditional single-material insulators are used, then manufacturing simplicity is maintained, but performance under combined environmental stresses deteriorates
Solution Approach 1:
The patent employs a composite structure with a ceramic core and polymer shell that can be manufactured through established processes such as overmolding, achieving complex performance requirements without excessive manufacturing complexity
Solution Approach 2:
The insulator is divided into two functional segments: a ceramic core for thermal and mechanical stability, and a polymer shell for flexibility and electrical insulation. This segmentation allows each material to perform its optimal function while maintaining manufacturability through standardized assembly processes

AI summary
An insulator that supports a line from a pin includes a core that defines an opening configured to receive the pin, and includes a shell formed from a polymer disposed over an outer surface of the core. The insulator also includes a head formed from the core or the shell, and configured to support the line spaced from the pin.
