JDZ9-20 / JDZ(X)F9-20G Voltage Transformer

The JDZ9-20 and JDZ(X)F9-20G are resin-cast voltage transformers designed for 20kV power systems. They offer high accuracy measurement (0.2/0.5 class) and reliable protection (6P class), with versatile configurations including single-phase, dual-winding, and residual voltage options. Featuring robust insulation (24/65/125kV) and compact design, these transformers are ideal for metering, protection, and control applications in switchgear and distribution systems.
