Product Description

20kv three phase double winding distribution transformer with off load tap
changer


Introduction:
It adopts advanced electromagnetic design software,and meets IEC60076,GB1094,GB/T6451,GB/T25289-2010 standards,without such 
device like conservator,air breather...,so it ensures that the transformer oil is not in contact with air,improving the anti-oxidation capacity of 
the transformer oil and delaying its aging. the core is made of high quality cold-rolled grain-oriented silicon steel sheet,with laminated 
structure miter joint,so as to reduce the no-load losses and no-load current. the tank is a corrugated type,the corrugated fins can swell and
shrink with the change of transformer oil,so that the pressure can be maintained inside the tank,increase its reliablility and anti-corrosion 
capacity.the coil of distribution transformer,wound by high intensity enameled wrapped conductors with good ampere-turn balance and 
reasonable insulation structure. has a strong short-circuit withstand capacity.the distribution transformer adopts the free-untanking structure.
with sealing material parts made of high quality acrylic rubber,it can effectively prevent againest ligh-aging and heat-aging.

Technical parameters:
Capacity: 30~2500kva 
Voltage :20± 5% or ± 2x2.5%  LV:0.4KV 
Vender group:Yyn0 or Dyn11
Impedance:5.5%, 6%
the loss value also apply to high voltage double voltage 20(10) three phase transformers.
