Had Fab Case Study

Detailed design, manufacture and installation of a Circuit Breaker Access Platform for Walham Substation.
Client: National Grid

Had Fab provides National Grid with detailed design, manufacture and installation of a circuit breaker access platform for the Walham Substation. Without Had Fab’s turnkey approach, this project could not have been completed on time. When an accelerated schedule of 4 months was requested following an outage, Had Fab’s design, fabrication and installation teams worked together to execute the project from start to finish.
