10 kV Oil Immersed Distribution Transformer
The product is the implementation of the national standard GB/T1094 “power transformer" ,GB/76451 “three—phase oil—immersed power transformer parameters and technical requirements’ and GB20050—2020 “power transformer limited value of energy efficiency and energy efficiency grade”
three-phase oil-immersed distribution transformers.Core material selection 30QG120,30QG100, 23RK085,18R060 and other cold-rolled silicon steel sheet,the actual core material used in the production of not less than design requirements.
The product is fully sealed structure of corrugated tank,transformer oil and the surrounding air does not contact the outside world so the transformer oil will not absorb moisture,so as not to reduce the insulation strength;addition of oxygen can not enter the tank,thus avoiding the aging of insulating materials,improved the life of the product,but also improve the social benefits.

Sealed Amorphous Alloy Core Distribution Transformer
The product isn full—filled sealed,sealed with the principle of power transformers.Based amorphous alloy elements are iron,nickeI,cobaIt,siIicon,boron,carbon and other components,is a soft isotronpic materials,magnetic power is small,there is no domain wall movement impede structural defects,the thickness of very thin,only 0.027mm,the corresponding filling factor smaller,only 0.75 to 0.8,resistivity is high,is the silicon steel plates 3 to 6 times,5times the hardness of the silicon steel,amorphous alloys are particularly sensitive to stress.
S(B)H—M series load loss products no—load loss in GB/76451 based on the standard set of I values decreased by 70%.Implementation of standard JB/T10318 ’oil—imm—ersed distribution transformer amorphous alloy core technical parameters’ and GB20050—2020 "power transformer limited value of energy efficiency and energy efficiency level".
