Product Introduction

Our factory’s H Grade Non-encapsulated insulation three-phase dry type transformer is manufactured with NOMEX insulation material which approbated by UL, and has many advantages of safe, reliable, energy-saving, fire-proof, explosion-proof, easy to maintain. Its design is advanced, structure is reasonable, appearance is pretty. Meanwhile, its main performance are superior to domestic standards, such as partial discharging level, no-load loss, with-load loss, low noise and can work under conditions with high damp, etc. It can be installed in areas with large load, be suitable for high-rise buildings, airports, railway stations, docks, subways, hospitals, electricity factories and so on.


Characteristics of H Grade Non-encapsulated dry type transformer:

1,The elaborate designed coil structure and vacuum immersed treatment enable    SG(B)10 transformer’s partial discharging volume be very small, less than or equal to 5pc. No crack performance will be found during the whole service life, and its insulation   level will be kept as good as beginning .


2.The high voltage part adopts continuous wire winding. LV foil winding, vacuum immersed, curing processed and high strength ceramics supporting, with fine withstand  capability to paroxysmal short-circuit current

 

3.Flame resisting, flameproof, nontoxic, self-extinguishing, fireproof.

 

4. When burn in high temperature and open fire, almost no fume will be produced


5. Insulation level of the transformer is H grade 

 

6.The insulation layer is very thin, with strong shorttime over load capability, needlessof forced cooling, can be overloaded for 120% for long term and 140% for 3 hours.


As this kind of insulation material has elasticity and will not be aged, it can be full     loaded at once under suitable conditions.
