IEC Bushing MV Voltage Transformer Proof Wound Safety And Isolating Energy
12/24/36kV Medium Voltage Transformer IEC Bushing Metallic Coating Touch Proof Wound Safety And Isolating Energy
1. Product Introduction:
Voltage transformer adopts fully enclosed casting insulation structure, which encloses the primary and secondary winding and the toroldal core In the epoxy resin casting body to Improve the filterability and moisture resistance. The product plug part Is designed to conform to the B type Inner cone (EN 50181). The overall structure is designed to be fully shielded surface. It is used indoor for measuring voltage, electric energy and protective relaying In single-phase or three-phase AC circuit with the frequency 50Hz or
60Hz and highest voltage for equipment 36kV.
Main technical parameter
1. Installation site: Indoor
2. Rated frequency: 50/60Hz
3. Load power factor: cos'=0.8 (lagging)
4. Technical standard accords with: I E C 60044-2
