2, stable, reliable, a long life time
3, good for heat dissipation
4, 110kv voltage transformer
JDC6(F)-110 Outdoor oil-immersed 110KV voltagetransformer
Feature
1, It is cascade structure, which the primary winding hasfour grade windings surrounded on each limbs of one single phasetwo-limb core. The insulation consists of high voltage cable paper,phone paper and cardboard etc, which will be immersed withtransformer oil after desiccating under vacuum. It has advantage ofstable and reliable performance of insulation, rich successfulexperience, a long life time and convenient maintenance
2, Perfect fluidity performance of transformer oilis good for heat dissipation, italso has self recover ability for the failure of partial dischargecaused by air bubble and dust.
It has two or three secondarywindings, which has individual measuring and meteringwinding.
3, Hermetically sealed stainlesssteel metallic bellows is installed on the top, which protects thetransformer oil from moisture and extend the life time, also thereis a oil level gauge on the bellows for observing the changing ofoil volume
4, There is a multifunction oildrain valve on the base, which makes it more convenient forsampling and draining
5, The secondary terminal boardis made of epoxy casting, the seal performance is morereliable.
