JDCF-220W1

JDCF-220W1 is a professional single-phase cascade oil-immersed voltage transformer designed for 220kV ultra-high voltage power systems. Complying with IEC and GB international standards, this outdoor potential transformer is widely used in large substations, backbone power grids and new energy projects for accurate voltage monitoring, energy metering and system relay protection.
Adopting advanced cascade insulation structure and high-purity insulating oil, the JDCF-220W1 features excellent ultra-high voltage insulation and stable heat dissipation performance. Equipped with low-loss silicon steel core, it maintains precise transformation ratio and high measuring accuracy, effectively resisting complex electromagnetic interference in high-voltage grid environments.
Built with a fully sealed structure and top metal expander, this 220kV voltage transformer effectively prevents oil leakage, moisture and dust intrusion. The high-strength anti-fouling porcelain sleeve with multi-layer anti-corrosion treatment ensures reliable all-weather operation in harsh environments such as high altitude, low temperature and coastal salt fog areas.
Optimized with balanced insulation and reasonable winding layout, the JDCF-220W1 has strong overload capacity and low operating noise. With long service life and low daily maintenance, it greatly reduces operation costs for 220kV power grid construction and upgrading projects.
As core supporting equipment for 220kV high voltage power engineering, JDCF-220W1 delivers high precision and superior operational stability. We provide factory direct supply, complete certification documents and professional after-sales service for global power engineering projects.
