Description
The S11-10kV oil-immersed transformer is a high-efficiency power transformer designed for medium-voltage electrical distribution systems. It plays a critical role in converting electrical energy from higher to lower voltage levels, ensuring safe and stable power supply across industrial facilities, manufacturing plants, commercial buildings, and substations.
Part of the well-known S11 series, this model uses mineral insulating oil and high-quality silicon steel cores to deliver improved performance, reduced no-load losses, and superior heat dissipation—making it ideal for continuous operation in demanding industrial environments.
lron core:
the iron core is made by crystal grain-oriented silicon-steel sheet; cross cut shear is adopted to cut the silicon-steel sheet with a 45*joint seam; fold the sheet into a multistage roll cross-section to reduce the noise and power consumption.
Coil:
cylinder type for high voltage; cylinder type or foil type for low voltage; this can increase the ability to resist short circuit and strike; and the distribution of magnetic path is more rational.
Oil tank:
the oil tank is made by fine cold-rolled steel sheets; corrugation oil tank production-line is adopted; to meet environmental needs, then, antiseptic coating material is applied on the surface, which can meet the requirements for petroleum and chemical industry (much oil stain and many chemical substances). In addition, the corrugations not any possess heat radiation function, but also meet the requirement for oil expansion and oil contraction trader normal performance. The isolation from air guarantees a low aging speed of oil and a long life expectancy of transformer.
Insulation structure:
oil-immersed distribution transformer adopts A-level insulation structure; high voltage coil and low voltage coil are concentric; the space between coils is cardboard sleeve small oil clearance oil partition structure.
