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
