JDCF / JDC5-220kV Series Voltage Transformer
Looking for a 220kV voltage transformer that meets both IEC and GB standards without long delivery times? Our single-phase porcelain-insulated CVTs are built for reliable metering and relay protection.
- Certified Compliance: Meets GB1207 and IEC 60044-2 standards. Certificates provided for grid approval.
- High Pollution Resistance: Up to 7560mm creepage distance, designed for severe pollution environments.
- Lower Operating Costs: Low magnetic flux density ensures strong anti-ferroresonance and low partial discharge.
- Project-Ready: Five-coil products available upon request to match your specific protection scheme.
Before You Send An Inquiry
Standard vs. Custom: Standard models ship quickly. For special high-altitude or heavy-pollution environments, send your project specs for a fast feasibility check.
Documentation: Full type test reports, routine test reports, and compliance certificates (GB/IEC) are available before shipment.
Lead Time: Confirmed in writing at quotation. We understand project deadlines and can discuss expedited shipping for urgent substation needs.
Packaging & Shipping: Heavy-duty export wooden cases with shockproof and moisture-proof protection for long-distance sea freight.

Core Advantages
Superior Sealing Life: Limited-position sealing design keeps all sealing components away from the atmosphere. This prevents oil leakage and extends maintenance intervals.
Mechanical Strength: Cast-on-flange porcelain bushing delivers high mechanical strength, reducing the risk of damage during transport and installation.
Stable Operation: Low partial discharge and low dielectric loss ensure stable metering and protection accuracy over decades.
Anti-Ferroresonance: Low magnetic flux density protects your system from ferroresonance issues and ensures a wide load range.
