Design and Structural Development of Substation Isolator Switch
Project Overview
This project focuses on the design and structural development of a Substation Isolator Switch tailored specifically to meet client-defined technical and operational requirements. Using SOLIDWORKS, a high-precision 3D CAD and simulation tool, the isolator switch structure was designed, modeled, and validated to ensure mechanical reliability, operational accuracy, and compliance with international qualitystandards. The outcome is a fully engineered and simulation-verified model that ensures safe operation, ease of manufacturing, and compatibility with high-voltage substation environments.
Design Requirements
- To design a mechanically robust and electrically reliable isolator switch model.
- To ensure compliance with IEEE C37.30.1-2022 standard for high-voltage switches.
- To ensure design accuracy tolerance for critical mating components.
- To provide customers with fully detailed 2D manufacturing drawings and 3D assemblies for review andproduction.
- Design review: Internal peer-review confirmed conformity with IEEE C37.30.1-2022 and client specifications.
- BOM accuracy: Verified with standard hardware and material availability for local manufacturing.
