1. Product Description-20250123-2634.webp

 

Our 11kV oil-immersed distribution transformers are a go-to for medium-voltage power distribution-we've supplied them for power utilities and industrial use for years, and they've always held up great in real-world use. We use tried-and-true oil-immersed insulation tech, so they run steady, disperse heat well, and last a long time, even when they're working in hot, tough conditions. We have capacities from 50 kVA all the way up to 60,000 kVA, and we can tweak the setup however you need to match your load requirements. The core is built for low loss, which cuts down on energy use when it's running, and the tough build means it keeps urban and rural power grids supplied safely and nonstop.

  •  
  • Works reliably in harsh environments
  • The 11kV oil-immersed distribution transformers system cools the unit really well, so the transformer stays stable even in hot, dusty areas or remote locations where conditions aren't ideal.
  • Low loss and high efficiency
  • We use an optimized core and top-grade cold-rolled grain-oriented silicon steel, so our transformers have low no-load and load losses. That means our customers save a lot on running costs over time.
  • Fully customizable
  • We can make adjustments to capacity, voltage ratio, tap range, loss levels, and all types of accessories. Just tell us your local grid standards or send over your project drawings, and we'll build it to match.
  • Easy maintenance and long service life
  • It's a simple design with mature technology, and spare parts are easy to get hold of-so even in remote areas, maintenance is never a hassle. With proper use and basic regular upkeep, these transformers can last 30 to 50 years.

 

 

 

3. Applications

  • Urban and rural power distribution networks
  • Public power substations
  • Industrial plants and factories
  • Mining and construction projects
  • Solar and hybrid energy systems
  • Infrastructure projects (hospitals, schools, commercial centers and more)

 

FAQ
 

Q1: What are the most commonly used capacities?

100kVA, 200kVA, 315kVA, 500kVA and 1000kVA are the most popular options. It just comes down to what your actual load demand is.

Q2: Can you customize the voltage ratio?

Absolutely. We'll design the primary and secondary voltages to fit the local grid standards you provide.

Q3: Which international standards do you follow?

We can manufacture to IEC 60076, ANSI or BS standards-whichever your project requires.

Q4: How long is the 11kV oil-immersed distribution transformers typical service life?

With correct installation and basic regular maintenance, our 11kV oil-immersed distribution transformers will easily last more than 30 years.
