Description
Description
Introduce

JDC6-110 type voltage transformer has single-phase three-winding cascade insulating structure,it is applicable to neutral point effective earthing systems of rated frequency 50Hz and 110kV ,used for voltage ,electric energy measurment and relaying protection.

The product has good excitation characteristic and strong antiresonance capability ,has reliable running,is convenient for maintenance,the top is installed with stainless steel metal corrugated expander featured with full-sealed structure.

LB6-110 is suitable for 8 teas of altitude up to 1000m

LB6-110GY is suitable for areas of altitude up to 3000m.

Features
This type of transformer insulation from epoxy resin core with high-quailty magnetic materials.Primary and secondary windings and core are cast in epoxy resin.
With excellent insulation properties and moisture resistance,and easy to do surface cleaning.
Qualifying time at the top of casting body,the outlet side marked as P1,P2,a secondary winding(measurment level)outlet side of 1S1,1S2,the second secondary winding(P) outlet side 2S1,2S2,mutual inductance is less class levels.
The base has four mounting holes for installation.
