Product Description

It is outdoor,single phase and oil immersed cascade inductive voltage transformer,
which is used for metering and relay protection of 66~230kV,50 or 60Hz system.

Standards:
IEC 61869-1;IEC 61869-3
GB 20840.1; GB 20840.3

Product Features

1.It is cascade structure,which the primary winding has two (220/230kV is four) grades,winding surrounded on core column of one (220/230kV is two)single phase two-limb  core.It  will be immersed in transformer oil after desiccating under vacuu. It has advantages of stable and reliable performance of insulation, rich operated experience, long service life and convenient maintenance.
2.Perfect fuidity performance of transformer oil is good for heat dissipation,it also has self restoring capacity for the failure of partial discharge caused by air bubble and dust.
3.It has three secondary winding,whose measuring and protective winding are separate.
4.Hermetically sealed stainless steel metallic bellows is installed on the top,which can protect the transformer oil and insulation paper from 
moisture and extend the life time,also there is a oil level gauge on the bellows for observing the change of oil volume.
5.There  is  a  multi  function  oil  drain  valve  on  the  base,which  makes  it  more convenient for oil sampling,draining and refilling.
6. All adopted insulation parts are environmental protection materials.
7.Secondary terminal board is made of epoxy casting,the seal performance is more reliable.
8.The base uses spray painting or hot galvanizing,which gives a high degree of corrosion  resistance.
9.Fasteners and nameplate are stainless steel.
