Build To specification
Distribution and power apparatus - from amorphous-core sets for the renewable estate to medium-power units between transmission and industry.
Engineering
The work is in the detail.
Designed to spec
Application-specific magnetic and dielectric design. Not a catalogue swap - every coil and core sized to the duty.
A transformer is a forty-year asset. We design, build, and test every unit to remove specification risk before steel is cut.
Witness-tested
Routine, type and special tests to IEC 60076. Clients welcomed at factory acceptance.
Loss optimised
Amorphous core and grain-oriented options. Loss capitalisation modelled across the asset life.
Delivered and commissioned
Heavy-lift haulage, site installation, oil-fill, and energisation - under one project number.
Services
Beyond the nameplate.
Manufacture is the start of the relationship. We move, install, commission, and maintain apparatus across Great Britain.
Site
Commissioning & Installation
Site-acceptance testing, oil-fill, vacuum processing, energisation and handover - delivered by our own engineering teams.
Logistics
Delivery & Transport
Abnormal-load haulage nationwide. Route surveys, lift planning, and offload coordinated end-to-end.
Lifetime
Maintenance & Repair
Preventive maintenance, oil sampling and DGA, tap changer service, and emergency response - for the full service life of every unit.
Designed and tested to
IEC 60076 EN 50588 EU Ecodesign Tier 2 BS 7821 ISO 9001
