CURRENT TRANSFORMER
□ 12kV 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 12kV
