Engineering Excellence, From Simulation to Site.
Ten precision manufacturing stages. One accredited testing lab. Complete traceability — from raw material to energisation.
Engineered Before It's Built
Every transformer is digitally modelled, simulated, and optimised before a single lamination is cut. CAD, FEA, thermal, and impulse analysis ensure first-time-right manufacturing.
Finite Element Analysis
3D electromagnetic and structural simulation to optimise core and winding geometry before manufacturing.
Thermal Modelling
CFD-based thermal analysis for hotspot prediction under all loading conditions, including 50°C+ ambient.
Impulse Simulation
Lightning and switching impulse voltage distribution analysis across all winding sections.
Loss Evaluation
Guaranteed no-load and load losses optimised to meet utility loss-evaluation criteria at tender stage.
Where Precision Meets Power.
Design
Electrical, mechanical, thermal, and insulation design; GTP & drawings.

Choosing the Right Dielectric for the Application
Insulating fluid choice drives fire safety, environmental footprint and life-cycle cost. ETS supplies transformers across the full modern range of dielectrics, each matched to the application and certified to the relevant IEC standard.
| Fluid / Type | Standard | Typical Use | Notes |
|---|---|---|---|
| Mineral Oil | IEC 60296 | General DNO / utility | Proven, cost-effective, widely available. |
| Natural Ester (Midel 1204) | IEC 62770 | BESS / renewable / urban | Fire safety, readily biodegradable, extended overload capability. |
| Synthetic Ester (Midel 7131) | IEC 61099 | Data centres / sensitive sites | High fire point (K-class), biodegradable, low pour point for cold climates. |
| Dry-Type Cast Resin | IEC 60076-11 | Indoor / data centre / EV | No fluid risk, IP-protected enclosures, low maintenance. |

Footprint & Transport Optimisation
Transformer design for the GB market must navigate constrained substation sites, strict road-transport envelopes, and proximity to residential areas. ETS engineering incorporates these constraints from the first design iteration.
Compact Footprint
Optimised tank and conservator geometry for constrained urban and semi-urban substation locations where site area is limited.
Transport-Envelope Compliance
Design-to-transport validation against UK road transport regulations covering width, height, and weight limits for abnormal loads.
Bund & Containment
Integrated bund and containment designs meeting UK oil-containment regulations (PPG2 / Environment Agency guidance) for pollution prevention.
Noise-Emission Optimisation
Core and tank design choices to minimise sound levels for residential-proximity applications and quiet-zone compliance.
Full Lifecycle Traceability
From incoming material inspection to final test reports and beyond — every component, every test, every decision is documented and traceable.
Material Review Board
Every incoming material is inspected and approved by MRB before entering production. Full traceability from supplier to final test report.
In-Process Inspection
Stage-gate quality checks at each manufacturing phase. Non-conformances are logged, resolved, and documented.
Final Documentation
Complete documentation package: type test reports, routine test results, material certificates, and commissioning guides.
Lifecycle Traceability
Every transformer has a unique serial number linked to its full manufacturing and test history — accessible for the entire asset life.
