1. Market Background
As a key hub along the "Belt and Road," Uzbekistan has significantly increased investment in electrical infrastructure. With the launch of numerous substation constructions and grid upgrades, the demand for high-purity aluminum strips-a core material for oil-immersed transformers-has surged. The geographical location makes railway transport the primary logistics choice, but the vibrations and temperature fluctuations during long-haul transit pose significant challenges for product packaging and reinforcement.
2. Client & Application Scenario
- Client Background: A leading electrical equipment manufacturer in Tashkent, Uzbekistan, specializing in distribution transformers.
- Application Scenario: The aluminum strips are used for low-voltage windings in oil-immersed transformers. The material requires not only high conductivity to reduce energy loss but also extreme edge smoothness to prevent discharge or breakdown in oil-immersed environments.
- Technical Challenge: The client previously faced issues with micro-burrs damaging the insulation layer. Furthermore, due to the long railway transit, previous supplies often suffered from core deformation caused by improper reinforcement, severely affecting the efficiency of automatic winding machines.
3. Our Solution
For the dual requirements of electrical performance and physical stability, we supplied 25 tons of 1050-O transformer aluminum strips and customized a specialized logistics reinforcement plan.
Key Technical Parameters:
- Grade & Conductivity： 1050-O state, with an aluminum content of ≥99.5%, ensuring excellent electrical conductivity and effectively reducing the operating load of transformers.
- Edge Quality：Precise edge trimming ensures completely burr-free edges, protecting the insulation paper of the transformer from damage.
- Thickness Tolerance：Strictly controlled within the range of ±0.02mm to ensure the tightness between winding layers and the uniformity of electromagnetic field distribution.
- Standardized Loading & Reinforcement: To counteract the lateral impact during railway transportation, we adopt a "cross-shaped" wooden frame support combined with steel band reinforcement, and apply anti-shake filling for 20-foot containers to ensure that the aluminum coils do not shift or shrink in diameter after long-distance transportation.
4. Feedback & Summary
- Client Feedback: The 25 tons of aluminum strips arrived in Tashkent safely via rail. Upon inspection, the client highly praised the rounded edge finish. Subsequent trial production on the winding machines was seamless, and the finished transformers fully passed the high-voltage resistance tests.
- Summary: This collaboration demonstrates our end-to-end control capability in the transformer aluminum sector. From burr-free edge processing to standardized railway container reinforcement, we provide not only premium substrates but also stability across the entire supply chain, supporting Uzbekistan's power infrastructure development.
