          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

          1、Rated insulation level: 24/50/125kV

          2、Rated frequency: 50/60Hz

          3、Installation site:  Indoor

          4、Technical standard: IEC 60044-1 & (IEC61869-1&2)
