SG(B)Non-sealed H grade Dry-type power transformer series

Product introduction

Non-sealed  H  grade  three  phase  dry  power  transformer   is  characterized  by  a  safe,reliable,energy saving,fire,explosion,does not produce harmful gases,no pollution,easy maintenance with advanced design,reasonable structure and good appearance and so on.The main performance indicators are better than national standards,have maintained throughout the lifetime of excellent electrical performance and mechanical properties.ldeal for high fire  safety  requirements,load  fluctuations,and  dirty  wet  environment,such  as  high-rise  buildings,airports,railway  stations,docks,subways,hospitals,powerplants,metallurgical industry,shopping centers,densely populated areas and  the petrochemical industry,nuclear power plants,nuclear submarines and other places.

Product features

High and low voltage winding insulation materials is used Nomex®and many times by VPl vacuum pressure  impregnation equipment,advanced agent-free varnish,external high-intensity H-class insulation sealand high tem- perature curing,operating conditions to ensure that no local discharges.

Transformer winding mechanical strength,thermal conditions are good (high and low voltage coils are used above 200℃ in long-term use of Nomex烟insulation)of the continuous structure,to avoid the multi-layer cylindrical coil voltage  is  high,poor  heat  dissipation,easy  to  thermal  breakdown  and  the  shortcomings  of  low  mechanical strength,thereby improving product reliability.
