JDCF-220W1
Featuring professional cascade insulation structure and high-purity insulating oil, the 220kV voltage transformer delivers superior ultra-high voltage insulation and heat dissipation performance. Adopting low-loss silicon steel core, JDCF-220W1 maintains stable transformation ratio and high measurement accuracy, effectively resisting voltage fluctuation and electromagnetic interference in complex grid working environments.
Built with a fully sealed integrated structure and top metal expander, the JDCF-220W1 voltage transformer effectively prevents oil leakage, moisture and dust ingress. The high-strength anti-fouling porcelain sleeve with multi-layer anti-corrosion treatment meets high pollution resistance standards, ensuring stable all-weather operation in high altitude, low temperature, coastal salt fog and industrial polluted areas.
Optimized with balanced insulation and reasonable winding layout, the JDCF-220W1 outdoor transformer has strong overload capacity, low operating noise and stable excitation performance. It features long service life and maintenance-free operation, greatly reducing operation and maintenance costs for 220kV large-scale power grid projects.
Serving as essential equipment for 220kV high voltage grid construction and upgrading, the JDCF-220W1 oil immersed voltage transformer boasts high precision and strong environmental adaptability. We provide global clients factory direct supply, customized solutions, complete certifications and reliable after-sales service for all power engineering projects.
