The JDZX9-36 and JDZX9-36J are 36kV indoor single-phase voltage transformers featuring epoxy resin casting and single-pole insulation. They are designed for use in isolated neutral systems, providing measurement of voltage, electric energy, and protective relaying in electrical systems operating at 50Hz or 60Hz, with a maximum equipment voltage rating of 36kV (up to 40.5kV).
Manufactured in accordance with IEC 60044-2:2003 and IEC 61869-1 & 3 standards, these transformers offer reliable and accurate performance. They support a load power factor of cosΦ=0.8 (lagging) and are suitable for indoor switchgear applications requiring stable, maintenance-free operation.
