Product Introduction
Structural Features: S18-4000KVA/35KV oil-immersed transformer adopts three-phase fully sealed all-copper design, with excellent thermal stability and mechanical strength, can maintain electrical performance in high temperature environment, and has excellent mechanical strength, can withstand most loads and transient loads. In addition, its fully sealed design reduces electronic oscillation sound and mechanical vibration sound, and prolongs service life.
Three-phase fully sealed all-copper transformer is an efficient and reliable power equipment, and its structural design is designed to achieve high insulation, low loss and long life.

| Model: | S18-4000KVA/35KV |
| Cooling method: | AN/ON |
| Voltage regulation method: | No voltage regulating tap changer |
| Connection group number: | YD11 |
| Short-circuit impedance: | 7% |
| Adopt corrugated oil tank: | low temperature rise, small footprint, beautiful appearance. |
| High and low voltage coils are directly wound on the core: | the two coils have good concentricity and strong short-circuit resistance. |
| The core is silicon steel strip: | it has good magnetic permeability and low hysteresis loss. |
| New insulation structure: | improves short-circuit resistance. |
| High-quality cold-rolled silicon steel sheet: | core material, improves the efficiency and stability of the transformer. |
| Oxygen-free copper wire: | high-voltage winding material, multi-layer cylindrical structure, reduces loss |
The rated capacities of S18 oil-immersed transformers are as follows:
200KVA: This capacity of S18 oil-immersed transformer is suitable for small electrical equipment and household electricity
315KVA: Suitable for small and medium-sized industrial and commercial applications, able to meet certain power needs
1250KVA: Suitable for large industrial and commercial facilities, able to provide stable power supply

Outlet device
The high and low voltage outlet terminals adopt a fully sealed structure, usually equipped with porcelain bushings or epoxy resin bushings to ensure insulation and moisture resistance.
Accessories
Oil level gauge: monitors oil level changes.
Desiccant (breather): used in non-fully sealed parts to prevent moisture from entering.
The three-phase fully sealed all-copper transformer has a compact structure and reliable operation. It is suitable for occasions with high requirements for safety and efficiency, such as urban power grids, industrial and mining enterprises, and high-rise buildings.
