Who we are
A parts supplier built around keeping plant running
Red Power Parts Limited supplies high and low voltage spares for transformers, switchgear and industrial power systems. Our customers are the people responsible for keeping substations, plant rooms and production lines live — maintenance engineers, electrical contractors, switchgear manufacturers and facilities teams.
Most of what we sell is the part that stops everything: a cable box, a gasket, a rating plate, a replacement throat. We hold stock, we source what has been discontinued, and where nothing exists any more, we manufacture it ourselves to drawing or sample.
Our mission
To make the awkward part easy — the right component, at a fair price, delivered when we said it would be, with someone on the end of the phone who understands what it does.
- Genuine and refurbished parts, checked before they leave us
- Obsolete and hard-to-find items sourced through our supplier network
- Honest lead times — we tell you when something has to be made
- One team for supply, fabrication and after-sales questions
Made in Yorkshire
Bespoke components fabricated in-house at our Wombwell workshop.
