Explore our top-tier range of CPRI type-tested, IEC & CE compliant transformers engineered for optimal stepped-down efficiency, heavy-duty thermal endurance, and seamless grid integration across Central Asia.
As Uzbekistan undergoes rapid economic transformation under its comprehensive National Energy Strategy 2030, the country is witnessing an unprecedented overhaul of its electrical distribution infrastructure. Transitioning from antiquated Soviet-era GOST electrical grids to modern, low-loss, CE-certified high-voltage step-down systems, Uzbek industrial buyers and municipal authorities are seeking electrical power supplies that combine rigorous safety compliance with robust thermal performance.
Manufacturing facilities, mining complexes, agricultural pumping stations, and urban infrastructure developments across Tashkent, Samarkand, Bukhara, and Navoiy demand transformers engineered to perform flawlessly under rigorous environmental conditions. Operating in Central Asia's harsh continental climate—where ambient summer temperatures regularly surge past +50°C in desert zones while winter temperatures drop significantly below sub-zero levels—requires transformers with enhanced insulation classes, precision-engineered cooling mechanisms, and strict voltage step-down stability.
Key Engineering Standard: CE marking on electrical power transformers guarantees full compliance with EU Low Voltage Directive (LVD 2014/35/EU) and Electromagnetic Compatibility Directive (EMC 2014/30/EU), alongside adherence to international IEC 60076 standards for power transformers.
With over three decades of core manufacturing expertise established since 1994, our manufacturing infrastructure is built upon precision engineering, ISO 9001:2015 quality management systems, and stringent testing methodologies. Every oil-cooled and dry-type transformer manufactured within our facilities undergoes rigorous routine, type, and special testing in full accordance with IS 2026, IS 1180, IS 11171, and IEC 60076 specifications.
Our power transformers are independently type-tested at the renowned Central Power Research Institute (CPRI), ensuring ultimate mechanical withstand capability during short-circuit conditions, low dielectric loss, and extended thermal longevity under continuous peak load operations.
Utilizing high-permeability, cold-rolled grain-oriented (CRGO) silicon steel cores (M3/M4 grades) to drastically reduce no-load hysteresis loss and acoustic noise levels.
High-conductivity electrolytic copper and aluminium conductors insulated with thermally upgraded Kraft paper or Class H VPI resin matrices for superior dielectric strength.
ONAN, ONAF, and dry-type AN/AF cooling configurations equipped with high-efficiency corrugated radiator fins to manage severe thermal dissipation requirements.
Integrated On-Load Tap Changers (OLTC) with Remote Tap Changer Cubicles (RTCC) and Automatic Voltage Relays (AVR) for active load regulation on fluctuating regional lines.
Uzbekistan’s diverse industrial landscape requires specialized transformer configurations tailored to specific operational challenges, grid voltages, and site conditions. Our CE-certified power supply solutions are customized to address regional infrastructure demands:
Heavy duty 10kV to 33kV step-down transformers designed to withstand harmonic distortions, severe dust exposure, and high peak loads in open-pit gold, copper, and mineral refining operations.
Pole-mounted single-phase and compact three-phase distribution transformers providing stable low-voltage step-down for high-capacity water pumping stations along the Syr Darya river network.
VPI Cast Resin Dry-Type Transformers up to 11kV installed in commercial skyscrapers, data centers, and underground sub-stations where zero fire hazard and low noise pollution are strictly required.
Step-up inverter transformers (0.4kV / 0.8kV to 35kV) engineered specifically for photovoltaic solar stations, handling bi-directional power flows and solar inverter pulse-width modulation harmonics.
The Uzbek power sector is under going a major transition driven by state-led privatization, energy diversification, and rigorous efficiency mandates set forth by the Ministry of Energy of Uzbekistan and Joint Stock Company "National Electric Grids of Uzbekistan" (NESU). Key industry trends include:
Uzbekistan is aggressively replacing outdated 6kV distribution lines with standardized 10kV, 20kV, and 35kV distribution networks to drastically lower line-loss transmission ratios across rural districts.
Industrial buyers in Tashkent Free Economic Zone and Angren SEZ are mandating international CE and IEC standards over regional GOST-R specs to ensure compatibility with European industrial machinery.
The rapid installation of utility-scale solar farms across southern provinces requires specialized step-up transformers capable of enduring high ambient thermal stress and continuous daily cycles.
Detailed technical answers to common procurement, import, thermal derating, and compliance inquiries from engineering leads and procurement managers in Uzbekistan.
Yes. While CE certification covers European safety, dielectric, and electromagnetic standards, our engineering team custom-configures the primary and secondary voltage ratios (such as 10kV/0.4kV, 35kV/10kV, or 6.3kV/0.22kV) and vector groups (Dyn11, Yyn0) to seamlessly harmonize with the grid parameters of National Electric Grids of Uzbekistan (NESU).
For high-ambient regions in Uzbekistan (Navoiy, Bukhara, Karakalpakstan), we calculate thermal derating according to IEC 60076-2 standards. We utilize oversized radiator cooling banks (ONAF option), premium Class H synthetic insulation, and top-grade mineral or ester transformer oil with high flash points to prevent dielectric breakdown under continuous +50°C ambient loads.
Hermetically sealed oil-immersed transformers (such as our S11-M series) completely isolate the insulating oil from atmospheric oxygen and moisture. This eliminates oil oxidation and sludging, drastically reducing routine maintenance cycles and extending total transformer operating lifespan—making them ideal for remote Uzbek industrial zones.
Yes. For installations in elevated terrains such as the Chatkal mountain slopes or Tian Shan foothills (>1000m above sea level), we design custom bushing insulation clearances and adjust dielectric withstand voltages to compensate for reduced air density and lower thermal dissipation capacities at high altitudes.
Every shipment is accompanied by complete commercial and engineering documentation, including CE Declaration of Conformity, CPRI Type Test Certificates, ISO 9001 quality audit reports, Factory Acceptance Test (FAT) datasheets, Certificate of Origin (COO), and detailed O&M manuals in English/Russian.
We supply transformers equipped with Off-Circuit Tap Changers (OCTC ±2x2.5%) or On-Load Tap Changers (OLTC) integrated with Remote Tap Changer Cubicles (RTCC) and Automatic Voltage Relays (AVR) to maintain a rock-steady secondary output of 400V/230V despite wide primary voltage swings.
When issuing a Request for Quotation (RFQ) or Tender Specification for power distribution transformers in Uzbekistan, local procurement committees should verify the following core parameters:
