Product Description
Oil-immersed Distribution Transformers
Product Introduction:
Oil-immersed Medium Voltage Transformer is totally closed ,without oil
storage cabinet ,which is lower than the transformers of the same kind.
Applied vacuum impregnating process, which removed the humidity of oil
tank completely; Oil and air don't contact each other, there's no
need to do oil sample test regularly.Leads of high voltage and low
voltage,body of transformers and other fastening parts are with screw nut;
we adopted no hanging core structure, transformer body and oil
tank are cooperated closely , which help transformers to bear the vibrationand
turbulence caused by transportation.The transformers adopted the ripple style ,
which has breath function ,and theelasticity of ripple style can compensate the
oil volume changes caused
by temperature changes;
Application:
High-rise buildings, commercial centers, city squares, hospitals, schools,
airports, railway stations, port terminals, subway, power plants, oil field,
chemicals, tunnels and other places.
Features:
Tow winding ,non-exciting regulation ,fully sealed;
With good insulation performance, reliable; It can be run under harsh environment;
Small size, light weight, easy installation and good economic performance;
Good overload capacity, low loss, low temperature, low noise;
High level of resistance to lightning impulse;
