Power Utilities & Grid
The backbone of national power infrastructure. ETS transformers are engineered for national utility fleet duty, type-tested to utility specifications and approved by leading regional utilities including DEWA, ADDC, SEWA and SEC.
ETS supplies directly in the UK ENATS-compliant 11 kV secondary substation transformers, 33 kV primary substation units and 132 kV grid transformers to UK Distribution Network Operators — UK DNOs — all BS EN 60076 type-tested with G99 grid-code interconnection support.
The Challenge
National utilities demand transformers that perform flawlessly for 30+ years under extreme conditions — sandstorms, 50°C+ ambient, voltage fluctuations — with zero tolerance for failure.
Our Solution
Our transformers are designed and type-tested to national utility specifications, with witnessed factory acceptance testing available on request. Approved by DEWA, ADDC, SEWA, SEC and other regional utilities.
Fleet-Standard. Utility-Approved. Grid-Ready.
Fleet-standard at 15+ national utilities across MENA
-witnessed short-circuit testing on every power transformer
50°C+ ambient temperature design as standard
Complete lifecycle support: maintenance, retrofit, monitoring
Grid-Expansion Transformers for National Utilities
Medium and large power transformers engineered for national utility grid-expansion programmes. Hermetically sealed 33/11 kV distribution units designed for 50°C+ ambient with witnessed type-testing available on request.
Where We Exceed the Standard
Our engineering team doesn't design to minimum specifications. Every parameter is pushed beyond industry norms — because your operations demand it.
Thermal Performance
Lower temperature rise extends insulation life by 2× and enables continuous overloading without derating — critical for Gulf ambient temperatures.
Short-Circuit Withstand
-witnessed dynamic and thermal short-circuit testing exceeds IEC 60076-5 requirements, ensuring survivability in the harshest fault conditions.
No-Load Losses
Amorphous and Hi-B laser-scribed core steel reduces no-load losses by up to 30%, delivering measurable TCO savings over the transformer's 35-year lifespan.
