High Voltage Banding With Insulative Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banding solutions are inadequate for high voltage environments as they can cause arcing and failure in such settings, posing risks to components and systems.
Innovation Solution
The development of banding with an inner core and an outer insulative layer, where the inner core has non-piercing edges and sufficient strength to secure components, and the outer insulative layer has a phase-to-ground rating greater than 15 kV, ensuring safe and secure attachment in high voltage environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional banding is used to secure components, then the banding provides sufficient mechanical strength to hold components together, but the banding causes arcing and failure in high voltage environments
Solution Approach 1:
The banding is divided into two distinct segments: an inner core that provides mechanical strength and an outer insulative layer that provides electrical insulation. This segmentation allows each layer to perform its specific function without compromising the other, resolving the contradiction between mechanical strength and high voltage reliability.
Solution Approach 2:
The banding uses a composite structure combining a metallic or non-metallic inner core with an outer insulative layer made of materials such as cross-linked polyethylene, silicone rubber, or ethylene propylene. This composite material approach enables the banding to simultaneously achieve mechanical strength from the inner core and electrical insulation from the outer layer, eliminating arcing in high voltage environments.
2Reliability
If an outer insulative layer is added to provide high voltage protection, then arcing is prevented, but the device complexity increases
Solution Approach 1:
The inner core and outer insulative layer are merged into a single integrated banding unit that functions as one component. The layers are bonded together through extrusion or other bonding methods, creating a unified structure that provides both mechanical strength and electrical insulation without requiring separate assembly steps or complex fastening mechanisms, thus minimizing device complexity.

AI summary
Banding and clamp for use to in high voltage environments of over 15 kV. The banding includes and inner core and an outer insulative layer. The inner core has non-piercing edges. The inner core is configured to have strength to prevent movement of components to which the banding is attached. The outer insulative layer surrounds at least a portion of the inner core. The outer insulative has a phase-to-ground rating of greater than 15 kV.
