Dielectric Hot Stick Clamp for Energized Flange Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for installing dielectric protectors on electrical power transmission systems require system downtime for de-energization, which is costly and often not feasible, and existing fastening methods complicate remote installation on energized equipment.
Innovation Solution
A tool comprising a first and second jaw that pivot relative to each other, with a tooth for fitting into a flange hole, and a hot stick made of dielectric material, allowing remote installation and secure positioning of dielectric protectors using an actuator from a safe distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing tools are used to install dielectric protectors, then the protectors can be secured in place, but system downtime is required for de-energization which is costly and often not feasible
Solution Approach 1:
A dielectric hot stick serves as an intermediary tool between the operator and the energized equipment. The hot stick allows the operator to remotely manipulate the clamp adapter and dielectric protector assembly without direct contact with energized components, enabling installation while the system remains energized and avoiding downtime.
Solution Approach 2:
The installation system is segmented into distinct components: the hot stick (operated from safe distance), the clamp adapter (provides gripping function), and the dielectric protector (provides insulation). This segmentation allows each component to perform its specific function independently, enabling remote installation on energized equipment.
2Ease of operation
If existing fastening methods are used, then protectors can be secured, but remote installation on energized equipment is complicated
Solution Approach 1:
The clamp adapter merges multiple functions into a single device: it provides mechanical gripping of the flange, electrical insulation between the operator and energized equipment, and a mounting interface for the dielectric protector. This consolidation simplifies the remote installation process while maintaining safety and functionality.
Solution Approach 2:
The clamp adapter acts as an intermediary mechanism that translates the operator's remote actions (applied through the hot stick) into secure fastening of the dielectric protector. It mediates between the remote operating requirement and the fastening requirement, enabling simple remote installation.

AI summary
A tool and method for handling a part within an electrical power transmission system is disclosed, the part having a flange with a hole through the flange. A first jaw and a second jaw are connected to pivot relative to one another and have respective ends that converge upon closure, for example to hold the flange between the respective ends. The first jaw may have a tooth extended at the respective end of the first jaw for fitting within the hole in the flange to hold the flange between the respective ends when the tool is in a closed position. The tool may be a hot stick adapter, or may include a hot stick made at least in part of dielectric material. An actuator may be connected to operate one or both of the first jaw and the second jaw from a user end of the hot stick.
