JDCF Series 66-230kv Oil-Immersed Cascade Inductive Voltage Transformer

It is an outdoor, single-phase and oil-immersed cascade inductive voltage transformer. This type of transformer is specifically designed to meet the requirements of the 66~230kV, 50 or 60Hz system. It plays a crucial role in the power grid as it is used for both metering and relay protection.

For metering, it accurately measures the voltage of the system, providing essential data for power consumption calculation and billing. In terms of relay protection, it can quickly detect any abnormal voltage changes within the specified voltage range and frequency, and then send out signals to trigger the corresponding protective actions to ensure the safe and stable operation of the power system. The oil immersion helps in effective insulation and heat dissipation, making it suitable for outdoor installation and continuous operation under different environmental conditions.

Customer Case 
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.
