Model JDZ Voltage Transformer

JDZ(X)(F)9-36 Voltage Transformer

Summary 

This model of voltage instrument transformers includes four versions: JDZ9-36,JDZF9-36, JDZX9-36 and JDZXF9-36. The units are cast in epoxy resin and fully enclosed. The units are suitable for electric systems of rated frequency of 50/60Hz and rated voltage of 36kV and below. They are used in indoor service conditions. The products are designed in accordance with Standards IEC60044-2 and GB1207-2006.
Structure feature
1. The units are cast in epoxy resin and fully enclosed.
2. Excellent in withstanding overload and electric arc / UV ray resistance.
3. Long life expectancy, long creepage distance, low in partial discharge.
4. Core and windings are cast together. A base plate is equipped at the bottom of transformer.
5. The version JDZ9-36 and JDZF9-36 are single-phase and connected in phase to phase.
6. JDZF9-36 units have two secondary windings, one electric energy metering and the other for voltage monitoring.
7. The version JDZX (F) 9 (including JDZX9-36 and JDZXF9-36) units are single-phase and connected in phase to earth.

The primary terminal A is connected to phase wire. JDZXF9-36 version has three secondary windings. These windings are respectively used for voltage monitoring, electric energy metering or relay protection.
