Adjustable Busway Joint Coupling for Offset Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical busway systems require custom-length joints, which are costly and time-consuming to manufacture, as fixed-length sections often do not match specific installation requirements, necessitating the need for adjustable length busway joints that can replace individual sections without removing adjacent sections.
Innovation Solution
A busway joint system with adjustable assemblies that allow for longitudinal movement between busway sections, using conductive busbars, splice plates, and insulation laminations, along with a compressive force mechanism to maintain electrical connection and prevent short circuits, enabling flexible length adjustment and secure installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed-length busway sections are used, then manufacturing and distribution is simplified, but custom-length joints are required for specific installations, increasing cost and installation time
Solution Approach 1:
The busway joint incorporates an adjustable length mechanism that allows the joint to be dynamically reconfigured to different lengths during installation. This dynamic adjustment capability eliminates the need for custom-manufactured joints for different installation distances, as the same standardized joint can be adjusted on-site to match any required length within its adjustment range.
Solution Approach 2:
The joint's length parameter is made variable through an adjustment mechanism that allows changing the effective length of the joint after manufacturing. This parameter change capability enables a single standardized joint design to serve multiple installation scenarios with different distance requirements, eliminating the need for custom-length manufacturing.
2Adaptability or versatility
If custom-length busway joints are manufactured, then specific installation requirements are met, but manufacturing cost and delivery time increase significantly
Solution Approach 1:
The busway joint is designed as a universal component with adjustable length capability, allowing a single standardized joint design to fulfill multiple installation requirements across different distances. This multi-functionality eliminates the need for separate custom-manufactured joints for each specific installation scenario, enabling immediate availability from standard inventory.
Solution Approach 2:
The joint is pre-manufactured with an adjustable mechanism built-in, preparing it for various length configurations before installation. This preliminary preparation of the adjustment capability allows the joint to be quickly configured on-site to match any required length without waiting for custom manufacturing and delivery.
3Reliability
If conventional fixed busway joints are used, then electrical connection is maintained, but replacement of a single section requires removal of adjacent sections
Solution Approach 1:
The busway joint is designed as an independent, self-contained module with adjustable length capability. This segmentation allows the joint to function as a standalone replaceable unit that can be removed and replaced without affecting adjacent busway sections, facilitating easy maintenance and repair while maintaining electrical continuity throughout the system.

AI summary
A busway system is provided. The busway system includes a first electrical busway section, a second electrical busway section, and a busway joint. The first and second electrical busway sections are disposed longitudinally offset from each other. The busway joint couples the first and second busway sections. The busway joint includes a plurality of busbars, a plurality of splice plates electrically coupled to the busbars, a first assembly coupled to the first electrical busway section, a second assembly coupled to the second electrical busway section, and an adjustment assembly coupled to the first and second assemblies. The splice plates and the busbars electrically couple the first and second electrical busway sections together. The adjustment assembly selectively moves the first and the second assemblies between a contracted position and an expanded position relative to each other.
