J---Voltage Transformer D---Single-phase Z---Pouring insulation X---With the remaining winding 8---Design numbez F---Measurement and monitoring of separate -35---Voltage kV G---Improved Design Structure Description This series of voltage transformer casting resin completely closed structure, core and winding pouring into one, the bottom mounting plate. JDZ (F) 8-35 for the single-phase, relative phase connection, JDZF8-35 has two secondary windings, the energy measurement and voltage monitoring separately; JDZX (F) 8-35 for the single-phase, relative to connectivity, the first A termination phase line, N grounded, JDZXF8-35 has three secondary windings, the energy measurement, voltage monitoring and relay separately. JDZX (F) 8-35G for the whole insulation structure, an A-phase line termination, N grounded, JDZXF8-35G has three secondary windings, the energy measurement, voltage monitoring and relay separately.
