The S13 series 10kV three-phase oil immersed distribution transformer is a new generation of energy-saving distribution products with higher safety and reliability. The iron core adopts high magnetic conductivity and low loss cold-rolled oriented silicon steel strip, and the magnetic flux density is far away from the magnetic saturation point, reducing the distortion of magnetic flux density and significantly reducing no-load loss and current.
This product meets the requirements of national standards: GB1094.1-1996 “General Principles for Power Transformers”, GB1094.2-1996 “Temperature Rise of Power Transformers”, GB1094.3-2003 “Insulation Level and Insulation Test of Power Transformers”, and GB1094.5-2008 “Short Circuit Capacity of Power Transformers”.
The S13-M-30~2500KVA three-phase oil immersed fully sealed distribution transformer is different from ordinary oil immersed transformers. It eliminates the oil storage tank and uses the corrugated plate heat dissipation fins of the oil box for heat dissipation and cooling. Its elastic expansion and contraction compensate for the increase or decrease in oil volume. All series of products are suitable for 10KV, 20KV, and 35KV transmission and distribution systems, and can be used for power and lighting in residential areas, commercial streets, industrial and mining enterprises, and rural areas.
Usage conditions
The S13 series power transformers are mainly suitable for factories, communities, schools, high-rise buildings, commercial centers, airports, etc., and can be used for power transmission and distribution in urban power grids.
