With a tight project schedule, the manufacturer delivered on time, and on-site technical personnel provided guidance throughout the entire installation and commissioning process; the collaboration was highly efficient and hassle-free.
S13 type distribution transformer
1. Low loss, fully sealed, non-excitation voltage regulation (5 levels), 24-hour uninterrupted power supply, long annual operating time.
2. Cooling method: ONAN oil-immersed self-cooling.
3. High-permeability cold-rolled grain-oriented silicon steel sheets (0.23mm grade), fully oblique joints, no punching, low noise, low loss.
4. Fully sealed corrugated oil tank: no oil conservator, corrugated plate automatically compensates for oil volume changes; completely isolated from the atmosphere, maintenance-free, prevents oil aging, and extends lifespan.
5. Windings: high-purity oxygen-free copper wire; cylindrical/continuous type, uniform oil channels, strong short-circuit resistance.
6. Standard application scenarios: urban residential communities, commercial complexes, office buildings; industrial parks, factories, enterprise power distribution, municipal public facilities; rural power grids, urban public transformer area renovation, etc.
7. Standardized design, special requirements can be customized.
Product Description
S13 Type Distribution Transformer - Advanced Power Solution for Your Facility
Our S13 type distribution transformer delivers enterprise-grade performance with impressive energy efficiency. Manufactured by Lijie Electric Power Technology Group across 500,000 square meters of advanced production facilities, this transformer features no-load loss reduction of up to 30% compared to previous models. With capacity ranging from 30-3150kVA and a fully sealed corrugated oil tank design, you get maintenance-free operation for years. Our team of 160+ engineers ensures every unit meets stringent quality standards, backed by annual sales exceeding 5 billion RMB and certifications including ISO 9001:2015, CE, and IEC compliance.
What Makes This Transformer Different?
Energy-Efficient Core Technology
You'll appreciate the shrewd building behind our control conveyance hardware. The center employs high-permeability cold-rolled grain-oriented silicon steel sheets at fair 0.23mm thickness. This isn't fair specialized jargon—it implies vital lowerity bills for you.
The completely angled joint plan dispenses with punching gaps. This diminishes operational commotion essentially. Your office remains calmer whereas devouring less power.
Fully Sealed Design Means Zero Maintenance
Here's where our item truly sparkles. The folded oil tank consequently compensates for oil volume changes. No oil conservator needed.
What does this cruel for you? The oil never contacts the air. It won't age or fall apart. You won't require standard support checks. Essentially introduce it and disregard around it.
This fixed framework expands the transformer's life expectancy significantly. You spare time and cash on upkeep.
Built to Last with Premium Materials
We utilize as it were high-purity oxygen-free copper wire for all windings. The round and hollow plan makes uniform oil channels all through. Warm disseminates productively. Short-circuit resistance remains solid indeed beneath requesting conditions.
The Dyn11 association bunch gives steady voltage control over five positions. You can alter from 19.5kV to 20.5kV without excitation.
