LZZBJ9-35 Current Transformer
- The LZZBJ-type epoxy resin-cast pillar current transformer is a fully enclosed pillar-type current transformer with cast epoxy resin insulation.
Pillar-Type Current Transformer Series
The LZZBJ-type epoxy resin-cast pillar current transformer is a fully enclosed pillar-type current transformer with cast epoxy resin insulation. It is suitable for AC power systems with rated frequency of 50Hz or 60Hz and rated voltage of 10kV, 20kV, 35kV and below, serving purposes of current measurement, energy metering, and relay protection.
Depending on current ratio, accuracy class, and rated burden, this series of current transformers is divided into several types. Specific parameters can be found in the corresponding parameter tables for each model (Note: Customized current transformer series with different specifications and parameters can be manufactured according to user requirements).
This type of transformer is an epoxy resin-cast fully enclosed pillar-type current transformer, suitable for AC power systems with a rated frequency of 50 or 60Hz and rated voltage up to 35kV. It is used for current measurement, energy metering, and relay protection. The product features excellent insulation performance and moisture resistance, with a higher safety operation coefficient, and has been widely implemented in various 35kV switchgears.
