We Build What Others Can't Supply
From one-off gaskets to full fabricated cable boxes — Red Power manufactures bespoke transformer components to your exact requirements. Fast turnaround, UK-made, built to last.
What We Fabricate
Every item is made to order — no minimum quantity, no standard sizes required.
Fabricated Boxes
Custom-fabricated enclosures and housings built to your exact specifications. We manufacture transformer boxes, junction boxes, and protective enclosures in a range of materials and finishes.
Custom Size Throats
Bespoke transformer throats manufactured to non-standard dimensions. Whether you need an unusual aperture, special flange pattern, or unique material, we can produce it to drawing.
HV & LV Cable Boxes
High and low voltage cable boxes fabricated to order. We produce single and multi-way configurations, with custom bushing arrangements and cable entry layouts.
Extension Boxes
Extension boxes designed to retrofit or expand existing transformer installations. Made to match your equipment footprint and rating requirements.
Radiator Elbows
Precision-fabricated radiator elbows and cooling pipe connections. Produced to match your transformer's cooling circuit geometry and pressure requirements.
Gaskets
Custom-cut gaskets in a variety of materials including cork, nitrile, EPDM, and silicone. We cut to any profile — transformer lids, flanges, cable box faces, and more.
Stickers & Labels
Replacement rating plate stickers, warning labels, and identification tags. Produced to BS/IEC standards or custom artwork. Suitable for indoor and outdoor use.
