Two Sets SFFZ-40000KVA 110/10/10kV Aluminum Winding Transformers Delivered Within 3 Months for New Chemical Plant Project in Kazakhstan

 

Supported by our integrated industry & trade production system, we have finished customized manufacturing, full factory testing and full set shipment of two sets SFFZ-40000KVA 110/10/10kV three-phase oil-immersed on-load tap-changing power transformers with aluminum windings. These units serve a large new chemical plant in Kazakhstan, supplying stable core power distribution equipment for high-voltage power supply of chemical zones and ensuring uninterrupted power for continuous chemical production.

I. Project Background & Client Core Challenges

Kazakhstan is expanding its local chemical industry rapidly. This new comprehensive chemical plant includes reaction workshops, raw material warehouses, water circulation systems and auxiliary facilities with complicated power loads running 24/7. Strict requirements are raised on power supply continuity, impact resistance, dust and corrosion resistance. Local power grid follows IEC international standards and Kazakhstan GOST access regulations. Imported high-voltage equipment must be equipped with complete compliance documents for customs clearance and operation. Main pain points of the client are listed below:

 

1.The plant requires two independent 10kV power distribution circuits, so dual 10kV low voltage output transformers are needed to supply main production workshop and auxiliary sections separately for load partition control.

 

2.Chemical site has heavy dust and slightly corrosive gas with wide temperature difference all year round. The minimum temperature in winter drops to -30℃. Ordinary transformers easily suffer corrosion, condensation and startup failure.

 

3.The overall construction schedule is tight. The whole process from drawing confirmation, production to packaging & shipment must be finished within 3 months, while local manufacturers usually need over 4 months.

 

4.The project has clear budget optimization demand. Aluminum winding is specified to balance equipment investment cost and stable operation, with two units delivered at one time.

Based on Kazakhstan’s cold, dry, dusty environment, heavy chemical load and tight schedule, our technical team optimized structure and anti-corrosion solutions, and customized dedicated power transformer solutions for chemical plants with dual low voltage output.

II. Special Customized Advantages of SFFZ-40000kVA Transformer

The two SFFZ-40000KVA 110/10/10kV aluminum winding transformers are upgraded for harsh chemical working conditions and central Asia frigid climate:

1.Dual independent 10kV low voltage output for multi-zone chemical loads With 110kV high voltage input and two separate 10kV winding outputs, the transformer connects two busbars of the plant separately. Maintenance on one circuit will not cut power of another area, supporting non-stop chemical production.

2.Optimized aluminum winding design with cost performance High-purity aluminum conductor windings with widened heat dissipation channels balance procurement cost and heat dissipation performance. Low-loss grain-oriented silicon steel core controls no-load loss for year-round continuous operation.

3.Anti-corrosion & low-temperature protection for Central Asia Thickened steel plates for oil tank and radiator with special low-temperature & chemical resistant coating. Low-temperature resistant rubber seals and antifreeze insulating oil enable stable operation from -30℃ to +42℃. Dust & rain shield prevents erosion from dust and salt air to reduce breakdown risk.

 

4.On-load voltage regulation for severe grid fluctuation High-quality on-load tap changer adjusts voltage under load to offset wide grid voltage variation in remote industrial zones of Kazakhstan, stabilizing 10kV output and protecting chemical motors & precision control systems.

5.Full intelligent monitoring for centralized chemical plant management Built-in online sensors for winding temperature, oil temperature, oil level and partial discharge with reserved remote communication interfaces, connecting plant DCS system for real-time status monitoring and early fault warning.

6.Designed and manufactured strictly in accordance with IEC 60076 and Kazakhstan GOST standards, full test reports meet local customs and power authority acceptance.

III. Integrated Industry & Trade Support: Delivery within 3 Months

1.Imported industrial equipment in Kazakhstan requires complete GOST certificates and bilingual test reports. Supported by our full self-owned production lines, we provide one-stop service including design, manufacturing, testing, certification and export packaging:

Full routine tests before delivery: DC resistance, voltage ratio, insulation withstand, loss, temperature rise, short-circuit resistance etc. English & Russian bilingual technical documents guarantee smooth customs clearance.

2.Self-contained whole production chain without outsourcing: Core processing, winding, vacuum drying and assembly are completed in our own workshop. Two transformers are produced in parallel to shorten lead time.

3.Export-grade shockproof & moisture-proof packaging: Reinforced steel base, multi-layer rust & waterproof film, separate wooden cases for fragile components to endure long ocean shipping and overland transportation across Central Asia.

4.Strict cycle control for 3-month on-time delivery: The full period from drawing confirmation to finished packaging is controlled within 3 months, matching civil and electrical construction progress of the chemical plant.

IV. Project Value & Central Asia Market Layout

After commissioning, the two SFFZ-40000kVA dual-low-voltage transformers will supply all production and auxiliary loads of the new chemical plant. Partition power supply greatly improves power reliability, while low-temperature anti-corrosion design adapts to local extreme climate and cuts long-term maintenance cost. This successful delivery highlights our core integrated industry-trade advantage: flexible aluminum/copper winding customization based on client budget, targeted optimization for chemical, mining and power station working conditions, and full lifecycle service covering drawing design, production, export certification, cross-border logistics and remote technical guidance. In the future, we will further develop chemical, energy and mining power distribution markets in Kazakhstan and other Central Asian countries, launching cost-effective transformers adapted to frigid, dusty and corrosive environments, and supplying high-quality Chinese power equipment for central Asia industrial infrastructure construction.
