LZZBJ-35 current transformer is a fully enclosed epoxy cast insulation product used for current and energy measurement and relay protection in outdoor vacuum circuit breakers with a rated frequency of 50Hz and a rated voltage of 35kV and below.

The core of LZZBJ-35 current transformer is made of high-quality rolled silicon steel sheets, which have good magnetic conductivity. The primary and secondary coils are positioned by molds and cast with epoxy resin. The primary coil leads out at the top and is fixed and installed by the upper flange. Due to strengthened insulation, it can operate normally under humid, condensed, and Class III pollution conditions.
