Irkutsk Oil & Gas Project
Project Overview
In Irkutsk, Siberia, a new oil and gas processing facility required robust power distribution equipment capable of uninterrupted operation in extreme cold—where winter temperatures regularly drop below -40°C. The client needed compact, highly reliable transformers that could fit into constrained indoor or semi-indoor electrical rooms while supporting continuous 24/7 production. Given the accelerated project timeline, minimizing commissioning risks and ensuring rapid energization were critical to on-schedule plant startup.
Key project requirements included
Full operability at -40°C and below without insulation degradation or startup issues
Compact footprint with enhanced protection for semi-enclosed industrial environments
High reliability for critical process loads (compressors, pumps, control systems)
Streamlined deployment with full technical support to align with fast-track construction
TSTY Electric’s Customized Solution
TSTY supplied custom SCB14-type cast-resin dry-type transformers engineered specifically for Arctic industrial use. Using a low-temperature casting process, the resin system remains stable and crack-free down to -45°C. Units were housed in IP31+ enclosures, packaged in reinforced export crates for transcontinental shipping, and supported by remote installation supervision and commissioning guidance.
Core Technical Adaptations
Low-temperature cast-resin process ensures insulation integrity at -45°C
Compact design with IP31+ enclosure for indoor/semi-indoor installation
Reinforced wooden export packaging for safe long-haul transport
Full technical support from drawings to energization and operator training

Engineered for CIS Countries, Validated Globally
In continuous-process industries like oil and gas, power isn’t just infrastructure—it’s operational continuity. This project succeeded by aligning material science, compact engineering, and responsive support.
Engineered Resin Integrity for Arctic Conditions
The specialized low-temperature cast-resin formulation prevents embrittlement and micro-cracking in deep freeze, ensuring consistent dielectric strength and mechanical stability throughout the Siberian winter.
Space-Efficient, Yet Fully Protected
Despite tight room constraints, the IP31+ enclosures provide adequate dust and drip protection while allowing passive cooling—critical for dry-type units in enclosed areas.
Accelerated Commissioning, Reduced Field Risk
Factory pre-testing and remote technical guidance enabled quick, smooth energization—supporting the client’s fast-track schedule without compromising safety or performance.
A Proven Partner for Harsh-Environment Energy
By delivering cold-certified, compact, and fully supported transformers on schedule, TSTY enabled reliable power for one of Siberia’s most demanding industrial facilities—demonstrating deep competence in CIS energy markets.
