Product Description

Oil-immersed Power Transformer

These oil-immersed transformers are widely used in residential communities, commercial complexes, industrial and mining enterprises, power stations, public facilities, and urban/rural power grid upgrading projects. They are suitable for 10kV / 20kV / 35kV distribution and transmission systems with stable performance in various load fluctuation conditions and harsh environments.

Power Transformer Overview
🚀 Product Advantages
  • High-quality silicon-steel core: Low no-load loss and low noise using high-grade silicon steel sheets with 45° multi-seam lamination.
  • Fully-sealed corrugated tank: Maintenance-free design keeps oil isolated from air, preventing oxidation and moisture.
  • Strong short-circuit withstand: Reinforced structure ensures excellent short-circuit tolerance and consistent quality.
  • High overload performance: Supports 1.5× rated capacity for 6 hours and up to 2.0× for 1 hour, ideal for peak seasons.
  • Compact & Appealing: Small footprint and clean design suitable for various installation environments.

Frequently Asked Questions
What is the typical lead time for orders?
Standard models typically ship within 15–30 days, while customized units require approximately 30–45 days depending on complexity.
Do you offer customization for specific voltage requirements?
Yes, we provide full OEM/ODM services. We can customize voltage levels (6kV to 35kV), capacity (up to 25000kVA), and frequency (50Hz/60Hz).
What standards do your transformers comply with?
All our transformers are manufactured according to the IEC60076 international standard and have passed ISO9001, ISO14001, and CE certifications.
What are the advantages of a fully-sealed corrugated tank?
The sealed design prevents transformer oil from contacting air, which eliminates oxidation and moisture ingress. This makes the unit maintenance-free and significantly extends its service life.
Can I choose between copper and aluminum windings?
Yes. While copper is our standard for high conductivity and durability, we offer aluminum windings as a cost-effective alternative for specific project needs.
What documents are provided for international shipping?
We provide a full export documentation package, including the Commercial Invoice, Packing List, Bill of Lading, and Certificate of Conformity (COC).
