>> Product Uses

Here are four specific application scenarios of Power Transformer:

1. Utility Substations & Grid Infrastructure

The SZ-13000-115/10.5 power transformer is ideal for 110kV/35kV substations, enabling efficient voltage conversion between transmission and distribution networks. With ONAN/ONAF cooling and >99.2% efficiency, it minimizes energy loss in grid operations. Its 8% short-circuit impedance ensures stability during peak loads, making it a reliable choice for national power grids and urban infrastructure projects.

2. Renewable Energy Integration (Solar/Wind Farms)

Designed for step-up applications in renewable plants, this transformer connects 35kV wind turbines or solar arrays to 115kV grids. The 120% overload capacity handles intermittent renewable generation, while UL/cUL certification meets global green energy standards. Over 50 units are deployed in Asian and North American wind farms.

3. Heavy Industrial Facilities (Mining/Metallurgy)

In mining and steel plants, the transformer’s reinforced tank (C5-M anti-corrosion coating) withstands harsh environments. The <65dB noise level complies with OSHA standards, and DGA monitoring prevents oil degradation from heavy loads. Custom ±8×1.25%/±9×1.78% taps adapt to volatile industrial demand.
