Product Overview
The 4000kVA power transformer is a large capacity core power distribution device in the 10kV/35kV power grid system. It is mainly used for voltage transformation, power transmission and distribution in the power system. With its advantages of large capacity, high efficiency and stable operation, it is widely used in large industrial and mining enterprises, new energy power plants (photovoltaic, wind power and energy storage), urban core power distribution hubs, large commercial complexes, data centers and key infrastructure projects. It is a key device to ensure the stable power supply in large scale power consumption scenarios, adapts to a variety of complex power consumption conditions and meets high load power demand.
The 4000kVA power transformer uses high permeability grain oriented silicon steel sheets, processed with a fully oblique joint and stepped stacking process, effectively reducing no load losses. The windings are made of high purity oxygen free copper, which has high conductivity and low losses. Combined with an optimized winding structure design, this further improves the power conversion efficiency. Long term operation can significantly save on electricity costs, which is in line with the trend of green and energy saving development.
