Product introduction
S11, S13 series of fully sealed oil-immersed transformers are suitable for AC 50Hz, the original working voltage 20kV and below the power system, as petroleum, metallurgy, chemical, textile, light industry and other enterprises and large dust places of the distribution transformer.
Coil core fully sealed distribution transformer, is a new generation of low-noise, low-loss transformer developed in recent years, its core without joints, a large reduction in no-load loss and no-load current, so that no-load current reduced by 60%~80%, high and low voltage coil on the core pillar continuous winding, winding tight, good concentricity, more enhanced product anti-theft performance. Noise reduction of more than 10 decibels. Lower temperature rise 16-20K. Due to the continuous winding of the iron core (pure circular cross section), the orientation of the silicon steel sheet is fully utilized, and the no-load loss is reduced by 20% to 30%.

Application scenarios
S11 series 10-3150KVA/ 10KV series distribution transformers have remarkable energy-saving effects, and its main feature is the use of new core materials. The magnetic circuit is evenly distributed, which greatly reduces the no-load excitation current and no-load loss. Improve the power factor, improve the quality of power supply, because the core is the all-inclined three-joint structure, so reliable operation, small size, light weight, low noise, good process, good heat dissipation, low temperature rise, no hanging core structure, no pollution, no maintenance, high efficiency. S11-10 ~ 31500KVA three-phase oil-immersed fully sealed power transformer is suitable for 10KV, 50Hz transmission and distribution system, for residential areas, commercial streets, industrial and mining enterprises and rural power and lighting.
