Production description
This product conforms to the national standard GB1094.1-2013(IEC 60076) power transformer and GB / T6451-2015 three phase oil immersed power transformer technical parameters and requirements. The three-phase oil -immersed distribution transformer applies new type insulating structure. The iron core is made of high-quality cold-rolled silicon-steel plate. High-voltage winding group is made up of high-quality oxygen-free copper lines and it adopts multi-layer drum type structure. All fasteners have been processed with special treatment to prevent them from loosening.
As high-tech product that promoted by the country, the product has many advantages such as high efficiency, low loss. Its social benefits are remarkable that it will save much of electricity consumption and operating cost.
Compared with the original SZ11, the average of SZ13no-load loss reduced by 20% or more, the no-load current is reduced by 25% or more, operating costs dropped by an average of more than 15%
    Relative to the conventional S11 type/S13 series three-phase double-winding and excitation surge of transformer power after manual voltage regulator, SZ11 SZ13 type series transformer can realize the load, through the controller on the ground remote power transformer to adjust the voltage, which can realize free power voltage regulator, reducing frequency of climbing and risk, greatly convenient for power operation personnel on site.
