LZZBJ9-12A1 、LZZBJ9-12A2
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 50- 60Hz and
highest voltage for equipment 12 kV
1、Rated insulation level: 12/28/75kV
2、Rated frequency: 50/60Hz
3、Installation site: Indoor
4、Technical standard: IEC 60044-1
(IEC 61869-1&2)
