S Series 10kv/20kv Oil-immersed Transformer
S Series 10kV/20kV Three‑Phase Oil‑Immersed Distribution Transformer
Our S‑series (S11/S13/S20/S22) oil‑immersed transformers are designed for 10kV or 20kV, 50Hz AC power systems. They serve as distribution transformers for industrial plants (petroleum, metallurgy, chemical, textile) and sites with heavy dust.
110kv Oil-immersed Transformer
110kV three-phase oil-immersed power transformer is a high-voltage power transmission and transformation equipment, designed for regional power grids, industrial power stations and large-scale power distribution projects.
S9 series oil-immersed distribution transformers are classic and reliable power distribution equipment widely used in global power grid systems. Featuring stable performance, low noise, reasonable loss rate and strong overload capacity, this conventional oil-filled transformer adopts mature manufacturing technology and off-circuit tap regulation design. Cost-effective and fully compliant with IEC international standards, it is ideal for urban and rural power grids, industrial plants, residential areas and general power distribution projects.
S11 series fully sealed oil-immersed distribution transformers are high-efficiency, low-loss power distribution equipment designed for 6kV, 10kV, 20kV and 35kV power systems. Featuring ultra-low no-load loss, low noise, maintenance-free operation and strong short-circuit resistance, this energy-saving transformer is widely used for residential, commercial, industrial and new energy power distribution projects, fully compliant with IEC international standards.
S13 series fully sealed oil-immersed distribution transformers are mainstream high-efficiency energy-saving power distribution equipment. Adopting advanced step-lap core technology and high-purity copper windings, it features ultra-low no-load loss, low noise, strong short-circuit resistance and maintenance-free operation. With higher cost performance than S11 and S9 series, this IEC-standard transformer is widely used for urban & rural power grids, industrial parks, commercial buildings and new energy distribution projects worldwide.
S20 series fully sealed oil-immersed distribution transformers are new-generation second-level energy-saving power distribution equipment. Adopting advanced amorphous alloy core technology and optimized electromagnetic design, it features ultra-low no-load loss, lower noise, higher efficiency and stronger short-circuit resistance compared with S11 and S13 series. Fully maintenance-free, widely used for urban & rural power grids, industrial parks, commercial and new energy power distribution projects, compliant with IEC 60076 international standards.
