Description

 

Model JDZ(J)W-12 potential transformer is single-phase multi-winding whole sealing epoxy pouring product. It is used both indoor for measurement of voltage and electric energy as well as relay protection in the electric system of rated frequency 50/60Hz and rated voltage 12kV or below.

 

Model

Voltage-Transformer-JDZ(J)W-12-2

This series of potential transformer is of epoxy pouring whole sealing insulation strcture. Encircled by rolled silicon steel strap and through annealing process, the iron core, together with primary winding and secondary winding, is formed by pouring epoxy. This transformer owns excellent dirt-proof and moisture resistant performances. Secondary connecting terminal is equipped with connecting protective terminal box, which has 3 different outlet directions. It is convenient in wiring, dirt-proof and thief-proof.
