6.6kv 11kv 33kv/0.4kv Power Transformer
The S13 fully-sealed oil-immersed power transformer from Qingdao Hengfengyou Electric Engineering Co., Ltd. is designed for primary and secondary voltage ratings of 6.6kV, 11kV, 33kV to 0.4kV. It uses a fully oil-filled sealed structure with a corrugated sheet box, eliminating the need for an oil conservator. The transformer’s volume adjusts to temperature and load changes via the corrugated oil tank, ensuring stability and reducing maintenance needs.
Core construction employs 30P series high-permeability oriented silicon steel sheets with a thickness of 0.27-0.30 mm and a unit iron loss of 1 W/kg, compared to standard S9 types using 0.30-0.35 mm sheets with 1.20-1.55 W/kg losses. Foil-wound coils and new insulating materials enhance resistance to high temperatures and impacts. The integral fuel tank, featuring a corrugated fin radiator, undergoes phosphating and multi-layer anti-rust spraying for durability and weather resistance.
These transformers are suited for power distribution networks where energy efficiency and reliability are critical. Buyers typically include utilities, industrial plants, and infrastructure projects requiring stable voltage transformation. The S13 model’s lower no-load loss and strong short-circuit resistance make it a preferred choice for modern distribution systems.
