Deformable Cable Support Isolates Power Lines from Trench Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing channels for protecting power cables in civil engineering installations fail to adequately insulate cables from humidity and environmental pressures, as they often come into contact with the trench walls and base, leading to potential damage.
Innovation Solution
A channel with a deformable support system that suspends and isolates cables from the trench walls and base, using angled sections and uprights with screws or rivets for fixation, ensuring the cables are not in direct contact with the infrastructure, and are covered by a flexible rubber sheath.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are laid directly on the trench base and walls, then installation is simple, but cables are exposed to humidity and environmental pressures causing damage
Solution Approach 1:
The patent introduces a deformable support as an intermediary element between the cables and the trench infrastructure. This support suspends the cables at a distance from the walls and base, preventing direct contact with harmful environmental factors while maintaining structural simplicity. The deformable nature of the support allows it to adapt to trench variations without requiring complex rigid support structures.
Solution Approach 2:
The patent employs a deformable support that can flex and adapt to the trench geometry. This flexible component provides adequate cable suspension and protection without requiring complex rigid structures, thereby resolving the contradiction between reliability and device complexity.
2Reliability
If cables are suspended away from trench walls and base, then insulation from humidity and pressures is improved, but installation and fixation complexity increases
Solution Approach 1:
The patent utilizes the deformable property of the support as a key parameter change. By making the support deformable rather than rigid, the system can adapt to various trench configurations and fixation points, simplifying the assembly process while maintaining effective cable suspension and environmental isolation.
3Reliability
If rigid support structures are used to suspend cables, then cable isolation is effective, but adaptability to different trench configurations is reduced
Solution Approach 1:
The patent employs a deformable support that can dynamically adapt its shape and position according to the trench configuration. This dynamic characteristic allows the support to maintain effective cable isolation across various trench geometries and conditions, resolving the contradiction between isolation effectiveness and adaptability.

AI summary
A conduit for the protection and insulation of electrical power cables, structured in a trench open along its longitudinal axis in civil engineering (CV) installations and with two zones (12a), (12b) of different heights (h1), (h2), where two cables (C) to be protected and angle profiles (1), (2) with a rubber sheath (5) covering the entire assembly are respectively placed. It has a deformable support (6) in which the cables (C) are placed, supported and suspended without direct contact with the civil engineering (CV) installation; two uprights (8a) and (8b) associated with the deformable support (6) and respectively placed on the angle profiles (1) (2) housed in the zone (12b) of lower height (h2); means for supporting the deformable support (6) in the uprights (8a) and (8b) and for fixing this assembly to the angle profiles (1), (2) forming with them a block concealed under the rubber sheath (5).
