Resin Encapsulated Dry-Type Transformers: Thermal & Dielectric Mastery in Kazakhstan
Kazakhstan presents one of the most demanding operational environments in the world for electrical distribution infrastructure. Spanning from the Caspian Basin in Atyrau to the continental steppes of Astana and Karaganda, power infrastructure must endure extreme seasonal temperature swings ranging from sub-zero winter blasts below -45°C to blistering summer heat exceeding +40°C. Traditional liquid-immersed transformers frequently encounter oil oxidation, seal degradation, and fire hazards in enclosed urban substations or underground mining facilities.
As a leading exporter and specialized manufacturer, our factory manufactures Cast Resin Dry-Type Transformers (CRT) engineered with advanced epoxy vacuum casting technology. By utilizing a high-fill mixture of quartz powder and epoxy resin formulated for ultra-low thermal expansion coefficients (CTE), our coils prevent structural micro-cracking during abrupt ambient thermal shocks. This ensures zero moisture penetration during humid spring thaws and long-term dielectric integrity across Central Asia's harsh climate zones.
Advanced Epoxy Resin Vacuum Casting Process
The core advantage of our resin transformers lies in the precision of our automated thin-film vacuum casting process. Primary and secondary coils are wound using high-purity electrolytic copper or electrical-grade aluminum foil conductors. Foil winding minimizes inter-turn voltage stress, eliminating axial short-circuit forces during grid surges. The assembled coils are placed inside hermetically sealed vacuum chambers where epoxy resin is injected under pressures lower than 1 mbar.
This process guarantees complete impregnation, leaving no micro-voids or air pockets. Consequently, our dry-type resin transformers achieve a partial discharge level of less than 5 pico-Coulombs (<5 pC)—significantly surpassing international IEC 60076-11 and GOST standards. Low partial discharge directly translates to extended operational lifespans exceeding 30 years with minimal maintenance required.
Key Technical Classifications for Kazakhstan Projects:
- Environmental Class C2: Rated for outdoor installation, transportation, and cold storage down to -45°C without insulation breakdown.
- Climatic Class E2: Engineered to withstand severe industrial pollution, high humidity condensation, and heavy chemical airborne dust present in metallurgical processing zones.
- Fire Behavior Class F1: Self-extinguishing materials certified to produce zero toxic smoke or corrosive fumes, ensuring safety in indoor commercial buildings and underground mines.
Industrial & Infrastructure Application Scenarios in Kazakhstan
Our resin transformers and specialized power distribution equipment are deployed across critical Kazakh sectors driving national industrialization and regional connectivity.
Railway Electrification & KTZ Corridors
Kazakhstan serves as the primary land bridge between East Asia and Europe under the Trans-Caspian International Transport Route (TITR). Our CE Certified 55kV 2x27.5kV 10MVA Traction Auto Transformers provide stable voltage step-down and phase balancing across long-distance electrified railway lines, supporting heavy locomotive freight throughput under severe frost.
Heavy Mining & Metallurgy in Karaganda & Pavlodar
The vast copper, iron ore, and aluminum extraction sites in East Kazakhstan require transformers capable of absorbing extreme harmonic distortions generated by high-power VFD drives and electric arc furnaces. Our dry-type isolation transformers and VFD fan auxiliary power units deliver vibration-resistant, flame-retardant performance inside mine shafts and smelting plants.
Oil & Gas Extraction Facilities in Atyrau & Aktau
In the Caspian coastal region, saline moisture, sulfur compounds, and volatile gas environments present high corrosion and fire risks. Our pre-assembled YBW Modular Compact Substations with IP54 cast resin enclosures isolate internal electrical components from atmospheric corrosion while delivering explosion-safe power to extraction pumps.
Urban Substation & Data Center Expansion in Astana & Almaty
Rapid urban growth and high-density commercial real estate development in Astana and Almaty demand space-saving, low-noise transformers. Dry-type cast resin units can be installed directly inside multi-story commercial basements, hospital power wings, and data centers without requiring expensive oil-containment pits or fire-suppression walls.

Strategic Energy & Grid Trends Shaping Kazakhstan
1. Modernization of Aging Grid Infrastructure
A significant portion of Kazakhstan's regional distribution substations—originally installed during the Soviet era—are reaching operational end-of-life. The Ministry of Energy is driving grid modernization initiatives to reduce distribution losses from over 15% to below 6%. Upgrading to low-loss, high-efficiency cast resin transformers is a key strategic priority for utility operators such as KEGOC.
2. Renewable Energy Acceleration (2060 Neutrality Goal)
Kazakhstan has committed to achieving carbon neutrality by 2060, expanding solar PV plants in Zhambyl and wind farms in Badamsha. Renewable energy generation requires multi-winding step-up inverter duty transformers capable of handling pulsating DC-to-AC power conversion and high harmonic vibration. Our dry-type and oil-immersed solar transformers meet these exact parameters.
3. EAEU Harmonization & EAEU TR Compliance
As a member of the Eurasian Economic Union (EAEU), electrical machinery imported into Kazakhstan must conform strictly to Technical Regulations CU TR 004/2011 (Low Voltage Equipment Safety) and CU TR 020/2011 (Electromagnetic Compatibility). Our factory offers fully certified documentation and test reports aligned with GOST and IEC benchmarks to streamline border customs clearance.
