Step-up transformer
1. High efficiency and energy saving
Significantly reduce equipment operating losses, minimize energy losses, and simultaneously balance long-term economic efficiency and environmental protection.
2. Low noise and high reliability
High-quality cold-rolled sheet steel with a silica structure and seamless connections across all stages ensures low noise levels and stable operation. A fully sealed design prevents oil leakage and ensures maintenance-free operation.
3. Excellent short circuit resistance.
Equipped with oxygen-free copper windings and a rigid construction, it provides high resistance to short circuits and grid impacts.
4. Long service life
A slight increase in temperature slows down the aging of the insulation, extending its service life and reducing overall operating and maintenance costs.

1. Core Performance Parameters (Customizable)
Energy Efficiency Level: Core iron core uses low-loss silicon steel sheets or amorphous alloy.
Heat Dissipation: Optimized oil-immersed/dry-type cooling structure. Oil-immersed type equipped with corrugated oil tank; dry-type can optionally feature intelligent temperature control fans. Overload temperature rise is strictly controlled.
Pressure regulation method: Supports loaded tap changer (OLTC) and unloaded tap changer. The range of the tap changer can be customized according to requirements.
Connection Group: Dyn11, Yyn0
Core: Three-dimensional winding (without seams, low loss) or stepped laminated iron core, selectable as per requirement.
Winding: Oxygen-free copper conductors, multi-layer segmented winding, with complete insulation protection.
Tank: Oil-immersed fully sealed corrugated oil tank (leak-proof, easy heat dissipation); dry-type with flame-retardant cold-rolled steel shell (dust-proof, moisture-proof).
Cooling: Oil-immersed default to natural cooling, can be upgraded to forced cooling; dry-type natural air cooling, optional forced air cooling.
Accessories: Standard features include temperature control, oil level indicator, etc. Optional intelligent monitoring and remote control modules.
2. Core Product Advantages
Strong overload capacity, ensuring continuous power supply, capable of handling seasonal peaks and equipment startup surges.
No need to configure based on peak load, reducing initial investment and expansion costs, high cost-effectiveness.
Oil-immersed/dry-type options available, voltage range 6300KVA - 125000KVA.
3. Typical Application Scenarios
Rural power grids: Address short-term high loads during festivals and farming seasons, reducing power grid renovation costs.
Industrial sector: Can withstand the startup load of electric furnaces and motor groups, anti-harmonic, ensuring production.
Urban distribution grids: Balance peak and off-peak loads, increase equipment utilization rate, suitable for residential areas and commercial areas.
New energy/infrastructure: Adapt to fluctuations in photovoltaic/wind power grid connection, ensuring stable power supply for data centers and rail transit.
