Power Utilities & Grid
The backbone of national power infrastructure. Our transformers are fleet-standard at 15+ utility companies — not trial units, but the units they deploy by the thousands.
ETS supplies IEC 60076 distribution transformers, package substations and power transformers up to 500 MVA / 400 kV to DEWA, ADDC, SEWA, FEWA and Saudi grid operators — supporting primary and secondary substation programmes across the UAE, KSA, Oman, Qatar, Kuwait and Bahrain.
DEWA Hassyan 400 kV grid transformer programme
ADDC Abu Dhabi distribution transformer fleet
SEWA Sharjah 132 kV primary substation supply
FEWA Northern Emirates secondary substations
Saudi Electricity Company 380 kV grid transformers
OETC Oman & QatarEnergy distribution programmes
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
We don't just meet utility specifications — we helped write them. Our transformers are type-tested, KEMA-witnessed, and approved by DEWA, ADDC, KAHRAMAA, SEWA, SEC, and 10+ more.
Fleet-Standard. Utility-Approved. Grid-Ready.
Fleet-standard at 15+ national utilities across MENA
KEMA-witnessed short-circuit testing on every power transformer
50°C+ ambient temperature design as standard
Complete lifecycle support: maintenance, retrofit, monitoring
Powering Dubai's Grid Expansion — 45 Units for DEWA
A fleet order of 45 hermetically sealed 33/11 kV distribution transformers deployed across Dubai's rapidly expanding network. Each unit designed for 50°C+ ambient with KEMA-witnessed type testing — delivered in 12 weeks, 100% first-pass acceptance.
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
KEMA-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.
