Cable Separator Beam Assembly for Short-Circuit Phase Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for restraining cables during short circuit events are labor-intensive and inefficient, as they require manual lashing of ropes around cables to secure like phases and maintain spacing between opposing phases.
Innovation Solution
A cable support system utilizing cable separator beams with half-cylindrically-shaped sleeves and end-caps, secured by elongated flexible fasteners, to organize and securely separate cables, preventing contact during short circuit events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cable lashing is used to secure cables during short circuit events, then cable restraint and spacing are achieved, but installation time and labor intensity increase significantly
Solution Approach 1:
The cable support system is divided into modular components including individual support elements, end caps, and fasteners that can be independently manufactured and assembled. Each support element can be pre-assembled and tested separately, then quickly installed as a complete module, reducing on-site installation time while maintaining restraint reliability.
Solution Approach 2:
Cable support elements and end caps are pre-assembled into complete support assemblies before installation. The fasteners are pre-positioned and configured, allowing the entire cable restraint system to be installed as a pre-configured unit rather than assembled during installation, significantly reducing installation time and labor intensity.
2Reliability
If traditional cable lashing methods are used, then cables are secured together, but the complexity of installation and maintenance increases
Solution Approach 1:
Multiple cable support functions are merged into a single integrated support element that simultaneously provides spacing, restraint, and alignment for multiple cables. The end caps and fasteners work together as a unified assembly, simplifying the installation process by reducing the number of separate components and steps required.
Solution Approach 2:
The cable support elements are designed with universal applicability to accommodate different cable sizes and configurations. The same basic support element design can be used for various cable types by adjusting the number of elements or end cap configurations, reducing the variety of components needed and simplifying installation procedures.
3Reliability
If manual lashing is performed to maintain cable phase spacing, then cable separation is achieved, but labor costs and installation effort increase
Solution Approach 1:
The cable support system is designed to self-align and self-secure during installation. The support elements automatically position themselves to maintain proper cable spacing, and the fasteners self-lock into place without requiring precise manual alignment or complex adjustment procedures, making installation straightforward and easy to perform.
Solution Approach 2:
The end caps serve as intermediary components that facilitate the connection between cable support elements and fasteners. These end caps provide a standardized interface that simplifies the assembly process, allowing workers to easily connect components without complex alignment procedures, thereby improving ease of operation while maintaining reliable cable spacing.

AI summary
A support for a plurality of cables includes one or more cable separator beams, each with a half-cylindrically-shaped sleeve formed on each end of each beam. A sleeve on one end of each beam is configured to align with a half-cylindrically-shaped end-cap to form an enclosed cylindrical space for passage of one of the plurality of cables. The second half-cylindrically-shaped sleeve on the other end of each beam is configured to align with the corresponding second half-cylindrically-shaped sleeve on the other of the two beams to form another enclosed cylindrical space for passage of another one of the plurality of cables. An elongated flexible fastener has a locking portion on one end thereof that fastens to a tail portion on the other end thereof, configured to surround and fasten the end caps to the beams, and the beams to each other, to secure and support the plurality of cables.
