S13 type oil-immersed 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. Applicable scenarios: urban residential areas, commercial complexes, industrial park power distribution rooms; supporting facilities for box-type substations, ring main units, and pole-mounted substations; locations with high requirements for energy saving, maintenance-free operation, and low noise.
7. Standardized design, special requirements can be customized.

Why Choose Our Oil-Immersed Transformers?
Advanced Energy Efficiency
You'll decrease working costs essentially with our S13 demonstrate. The transformer accomplishes lower no-load and stack misfortunes compared to S11 forerunners. High-permeability cold-rolled grain-oriented silicon steel sheets (0.23mm review) minimize vitality squander. Your office benefits from 24-hour continuous control supply with amplified yearly working time.
Maintenance-Free Design
The completely fixed layered oil tank kills your support cerebral pains. No oil conservator implies the folded plate consequently compensates for oil volume changes. Your transformer remains totally disconnected from climatic defilement. This anticipates oil maturing and amplifies benefit life substantially.
Superior Construction Quality
We utilize as it were high-purity oxygen-free copper wire for windings. The round and hollow continuous-type plan guarantees uniform oil channels all through. You get solid short-circuit resistance and dependable execution. Completely diagonal joints with no punching diminish both commotion and misfortune.
Flexible Customization
Your specific requirements matter to us. Standard configurations include:
- Capacity range: 30-3150kVA
- Frequency: 50Hz or 60Hz options
- Phases: Single-phase or three-phase
- Tap range: ±5%, ±2×2.5%
Production cycles run 6-30 days depending on your specifications.
