JDZX18-10R 電壓互感器

JDZX18-12R voltage transformer, epoxy resin casting and full enclosed construction, is used indoor switch cabinet to measure the current, electric energy and protective relaying in single phase or three phase AC circuit with the frequency 50Hz or 60Hz and highest voltage for equipment 17.5/24 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.
