Spool Applicator for Energized Cable Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying conductor covers to energized cables require power downs, which are costly and often result in significant delays due to scheduling challenges and increased risk of power outages caused by wildlife contact.
Innovation Solution
A conductor cover applicator with a spool system that allows for the pre-application of tubular, split conductor covers around a spool, which can be easily rotated and locked in place using a hot stick, enabling safe and efficient application to energized cables without the need for power downs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power down is performed to apply conductor cover, then safety is improved, but productivity deteriorates due to scheduling delays and power outages
Solution Approach 1:
The conductor cover is pre-assembled onto the applicator device before approaching the energized conductor. The cover is positioned and secured in advance, allowing rapid deployment when the applicator is brought into position, eliminating the need for time-consuming on-site assembly during power outages
Solution Approach 2:
The invention enables skipping the power down step entirely by using an insulated applicator that can safely approach and apply the conductor cover to energized conductors. The process rushes through the application in a single controlled motion without interruption for system shutdown
2Reliability
If power down is performed to apply conductor cover, then safety is improved, but loss of time worsens due to scheduling challenges and outage delays
Solution Approach 1:
The conductor cover and applicator are prepared together in advance, with the cover pre-positioned on the applicator. This preliminary assembly eliminates time-consuming on-site preparation and scheduling coordination, allowing immediate deployment when needed
Solution Approach 2:
The method skips the time-consuming power down and system shutdown procedures by enabling direct application to energized conductors. The entire application process is rushed through in a single controlled operation, minimizing loss of time
3Ease of operation
If spool system is used to store and apply conductor cover, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The applicator device is segmented into distinct functional components: a spool for storing the conductor cover, a mechanism for unwinding the cover, and an application head. This segmentation allows each component to be optimized independently and simplifies the overall operation by separating storage from application functions
Solution Approach 2:
The spool acts as an intermediary between the stored conductor cover material and the application process. It provides a controlled interface for unwinding and feeding the cover onto the applicator, simplifying the operation by mediating the transition from storage to application state

AI summary
Applicators and methods for applying a conductor cover to a cable, the conductor cover being tubular and split longitudinally to define a first longitudinal edge and a second longitudinal edge. The applicator comprises: a structural element; a spool connected to rotate relative to the structural element, the spool being sized to store the conductor cover in a pre-application state where the conductor cover is wrapped one or more times around the spool with the first longitudinal edge and the second longitudinal edge of the conductor cover spread open and perpendicular to a spool axis; and a lock for holding the conductor cover in the pre-application state.
