JDZX16-12R 12kV Indoor Single-Phase Transformer MV Voltage Transformer Potential transformer
1.Product Introduction:
Epoxy resin casting and full enclosed construction, is used indoor switch cabinet to measure the voltage, electric energy and protective relaying in single phase or three phase AC circuit with the frequency 50Hz or 60Hz and highest voltage for equipment 12 kV.
The iron core adopts advanced cold-rolled silicon steel sheet. High voltage outgoing line of primary winding was fetched out from top of the product; outgoing line of secondary winding was fetched out
from transverse side of the product.
The primary cone accords with IEEE 386-2006 figure 7.
