Bringing Remote Control to Legacy Grid Switchgear

Partnered with a client to modernize the UK’s aging electrical infrastructure by designing the mechanical systems that enable their remote actuators to be retrofitted onto 1960s-era switchgear, drastically reducing outage times.

Infrastructure Era Original Design (1960s): Predates CAD, remote operation, and digital records.
On-Site Process Reverse-engineered from scratch
Core Fix Epicyclic gearbox redesigned
Deployment Adaptable to multiple units

// The problem & the solution

// Technical Highlights

Focus	Engineering Action	Result
Legacy Integration	Reverse-engineered 1960s switchgear on-site	Created a digital foundation for retrofit
Universal Mounting	Designed adaptable brackets & tooling	One actuator fits nationwide
Core Mechanism Fix	Redesigned gearbox and validated with 3D prints.	Resolved key durability issues
Low-Volume Production	Managed prototype to fabricated parts	Delivered functional, installable hardware

// Value Delivered & Results

Enabled the remote monitoring and control of old switchgear, slashing outage times from hours to potentially minutes.

Fixed gearbox, added universal brackets, delivered production-ready system.

Bridged a 70-year technology gap with practical mechanical design.

Client Feedback:

"Core Mech were an excellent addition to my project. They leveraged considerable knowledge to make valuable recommendations and guide the design process effectively. They were flexible with multiple revisions, regularly available to discuss problems we were working through, and stuck to schedule. Most importantly, I got a high quality design at the end of the project. I highly recommend CMD if you are looking for a quality mechanical engineer/CAD expert for your next project."
