.
Structural characteristics:
This type of voltage transformer is a fully enclosed product. The primary and secondary windings and iron core are cast in epoxy resin, which has excellent insulation properties and is resistant to moisture. In addition to JDZX9-10Q for semi-insulated structure, the rest are fully insulated structure.
The first and second windings and core are cast in epoxy resin.
General
This type of voltage transformer adopts epoxy-resin vacuum casting and a fully closed single-phase structure for indoor use, is applicable for power systems of rated frequency 50Hz or 60Hz and rated voltage up to and including 10kV, used for electric energy metering and voltage measurement.
It complies with the standards GB 20840.1-2010 Instrument transformers-Part1:General requirements, GB 20840.3-2013 Instrument transformers-Part3:Additional requirements for inductive voltage transformers, and JJG314-2010 Instrument Voltage Transformers.
