Construction
The JDZC6-10Q employs an outdoor-rated epoxy cast-resin insulation system, fully encapsulating the core and windings to ensure protection against moisture, pollution, and UV exposure. The primary and secondary windings are embedded within high-quality epoxy resin, providing excellent dielectric strength and mechanical stability. This solid-insulation construction eliminates the risk of leakage or fire associated with oil-filled designs and requires no maintenance during service life. The compact housing is designed for direct outdoor mounting on poles or structures in medium-voltage distribution networks.

Installation & Wiring
Installation Diagram
The JDZC6-10Q outdoor epoxy cast-resin voltage transformer must be installed in accordance with the approved outline drawing, wiring diagram, and outdoor installation layout. Mount the unit securely using the four M8 mounting holes on the metal base, ensuring proper alignment and structural support. Maintain adequate insulation clearance around the unit and verify correct terminal connections before energizing.
Selection & FAQs
Selection Guide
- Distinguish ratio from equipment class: select this model for a 10000V primary; 12kV describes the equipment class and insulation level, not a confirmed 12000V winding.
- Select metering accuracy: use the 100V 2a–2b winding at class 0.2/30VA or class 0.5/50VA after calculating instruments and lead voltage drop.
- Check auxiliary demand: keep the 220V 1a–1b load within 500VA and verify inrush, duty, power factor and voltage regulation for the connected device.
- Assess the outdoor site: obtain verified creepage, UV, pollution, condensation, altitude, ingress and low-temperature data because only −5°C to +40°C is published.
- Coordinate installation protection: approve the 12/40/75kV level, clearances, four-M8 support, surge protection, secondary fuses or MCBs, protective earth and terminal sealing.
