Offset Cable Hanger Locking Structure for Wind Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable hangers for supporting cables in solar power plants face challenges such as high costs, vulnerability to harsh environmental conditions, and instability in high-wind environments, which can lead to displacement and reduced contact surface area with support structures.
Innovation Solution
The proposed cable hanger system includes a support member with offset saddles and a hanging mechanism that provides a positive locking mechanism to secure the cable hanger to a support wire, ensuring stability and balance even when loaded with cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable hangers are used to support cables in solar power plants, then cable support function is achieved, but high cost is incurred
Solution Approach 1:
The cable hanger is divided into separate components: a support member with multiple saddles and a hanging mechanism. This segmentation allows for standardized mass production of individual parts, reducing manufacturing costs while maintaining the overall cable support function.
Solution Approach 2:
The support member is designed to accommodate multiple cables through multiple saddles, making it a multi-functional component that can support various cable configurations. This universality reduces the need for different types of hangers for different cable arrangements, thereby reducing overall system cost.
2Reliability
If cable hangers are exposed to harsh environmental conditions, then cable support is provided, but vulnerability to environmental damage occurs
Solution Approach 1:
The cable hanger components are made from materials with composite properties that provide both mechanical strength for cable support and resistance to environmental factors such as UV radiation and corrosion. This allows the hanger to maintain its support function while being protected against environmental damage.
3Reliability
If cable hangers are used in high-wind environments, then cable support is maintained, but instability and displacement occur
Solution Approach 1:
The hanging mechanism incorporates a positive locking feature that acts as a counterbalancing force against wind-induced displacement. This locking mechanism engages with the support structure to prevent the hanger from being moved by high winds, thereby maintaining cable support stability.
Solution Approach 2:
The positive locking mechanism in the hanging mechanism automatically engages and secures the hanger to the support structure without requiring additional active components. This self-securing feature ensures the hanger remains stable in high-wind conditions while maintaining its cable support function.
4Reliability
If cable hangers are loaded with cables, then cable support capacity is increased, but rotation and displacement occur
Solution Approach 1:
The positive locking mechanism in the hanging mechanism provides a counterbalancing force that prevents rotation and displacement of the hanger when loaded with cables. This locking feature ensures the hanger remains securely positioned while supporting the increased weight and load from multiple cables.

AI summary
Systems are provided for a cable hangers. A system for cable hangers can include a cable hanger having a support member including a proximal end and a distal end. A plurality of saddles are attached to and extend from the support member, with each saddle of the plurality of saddles being configured to support at least one cable on a cable supporting surface. A hanging mechanism is arranged at the proximal end of the support member, where the hanging mechanism is offset on the support member.
