Radiastar successfully exported a high-performance 60MVA transformer oil tank assembly to a railway transportation energy project in Russia. The equipment is used in the local electrified railway power supply system upgrade, playing a critical role in supporting and stabilizing the internal insulation oil circulation system of the transformer. This places extremely high requirements on structural strength, sealing performance, and long-distance transportation reliability.

Project Specifications

The delivered equipment features the following key parameters:

• Product: Traction Transformer Oil Tank Assembly
• Rated Capacity: 60MVA application
• Total Weight: Approximately 95 tons
• Shipment Type: Single-piece transportation
• Overall Dimensions: 8100 × 4320 × 4850 mm
• Destination: Russia
• Application: Railway electrification power system

Due to its ultra-large and heavy-duty structure, the transformer tank required advanced engineering design and strict manufacturing control.

Engineering Design Optimization

During the design stage, Radiastar carried out comprehensive structural optimization to ensure performance under demanding operating conditions.

Key improvements include:

• Reinforced stiffener layout for enhanced structural rigidity
• Optimized load-bearing tank design for 95T transportation requirements
• High-strength steel materials applied for improved mechanical performance
• Multi-layer anti-corrosion coating system for extended service life

These enhancements ensure reliable operation in extreme cold climates and long-term continuous service environments.

Transportation & Export Solution

For this project, a specialized heavy cargo transportation solution was implemented.

The production process included:

• Complete factory pre-assembly
• Pressure and sealing tests before shipment
• Strict quality inspection and structural verification

The equipment was then transported via a professional heavy-duty logistics route to the project site in Russia. This ensured structural integrity and sealing stability throughout long-distance international transportation.

Project Significance

The successful delivery of this project further demonstrates Radiastar’s strong capability in the design, manufacturing, and export of large-scale transformer oil tanks.

It particularly highlights the company’s expertise in:

• High-capacity traction transformer supporting equipment (60MVA and above)
• Large-scale heavy structural component engineering
• International export project execution and logistics coordination

Radiastar continues to provide reliable and high-performance transformer tank solutions for global power transmission and railway electrification projects.
