The SG(B)series dry-type transformer adopts the NOMEX insulation system material from DuPont in the United States,with a temperature resistance level of H and higher fire resistance performance.The product has strong resistance to thermal shock,high overload capacity,flame retardancy,high fire resistance,and insensitivity to humidity and dust,which makes it widely adaptable and suitable for use in harsh environments with high fire protection requirements,large load fluctuations,and dirty and humid conditions

　　Product features:

　　1.Adopting NOMEX paper insulation system,it is flame retardant,explosion-proof,non polluting,and has a high fire rating.

　　2.Good heat dissipation effect,strong overload capacity,and can operate stably for a long time under 120%load.

　　3.Good insulation performance,high lightning resistance,and strong ability to withstand sudden short circuits.

　　4.Able to operate normally under harsh conditions(including climate and geographical environment).

　　5.After the end of its service life,it can be decomposed and recycled without polluting the environment
