LZZBJ9-24-180b/2 、 LZZBJ9-24-180b/4
CURRENT TRANSFORMER
□ 24kV Indoor Single-Phase Epoxy Resin Type
Epoxy resin casting insulation and fully enclosed support construction,
encloses primary & secondary windings and annular core in the epoxy resin
casting body. The product has the feature of light weight, omnidirectional
installation, withstanding nastiness and dampness. It is widely used for
measuring current, electric energy and protective relaying in the electrical
system with the rated frequency 50Hz or 60Hz and highest voltage for
equipment 17.5(24) kV
Technical Data
