Flexible Cable Splice for Angled Overhead Power Line Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigid splices struggle to make angled transitions between conductors during the installation of overhead power transmission lines, limiting their flexibility and usability in stringing processes.
Innovation Solution
A flexible housing with moveable casings and a connecting member that allows for relative movement between the casings, providing both physical and electrical connections between conductors, and is capable of making angled transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid splicing connectors are used to join conductors, then structural strength and stability are improved, but flexibility and ability to make angled transitions deteriorate
Solution Approach 1:
The splicing connector transitions from a rigid structure to a flexible structure that can dynamically adapt to different installation angles and positions. The flexible housing allows the connector to bend and flex during the stringing process, enabling angled transitions between conductors while maintaining structural integrity through the connecting member.
Solution Approach 2:
The splicing connector employs a flexible housing that replaces rigid enclosures. This flexible shell allows the connector to bend and flex to accommodate various installation angles and positions, while the connecting member within maintains the structural strength needed for reliable electrical connection.
2Stability of the object's composition
If rigid splicing connectors are used during cable stringing, then connection stability is improved, but ease of installation and accommodation of offset angles deteriorate
Solution Approach 1:
The connector is designed to be flexible during installation, allowing it to adapt to offset angles and positions as cables are stringed along poles. Once installed, the connecting member provides stable electrical connection, maintaining connection stability while enabling easier installation at various angles.
Solution Approach 2:
The connector changes its physical state from flexible during installation to stable after installation. The flexible housing enables easy operation during stringing, while the connecting member ensures connection stability is maintained once the splice is complete.
3Adaptability or versatility
If flexible housing with moveable casings is used, then flexibility and ease of angled transitions are improved, but structural rigidity and manufacturing complexity increase
Solution Approach 1:
The splicing connector is divided into separate components: a flexible housing and a connecting member. This segmentation allows the housing to be flexible for ease of installation while the connecting member provides the necessary structural integrity, managing overall device complexity through modular design.
Solution Approach 2:
The flexible housing and connecting member are combined into a single integrated splicing connector assembly. This merging allows the flexible housing to accommodate angled transitions while the integrated connecting member maintains structural rigidity, achieving both flexibility and strength without excessive complexity.
