LVB-220W2

LVB-220W2 is a high-performance single-phase oil-immersed current transformer designed for 220kV ultra-high voltage power systems. Complying with IEC and GB international standards, this outdoor current transformer is widely applied in 220kV main substations, backbone power grids and large new energy projects for precise current monitoring, energy metering and reliable system relay protection.
Adopting advanced capacitive graded oil-paper insulation structure and high-purity insulating oil, the LVB-220W2 ensures uniform electric field distribution, low dielectric loss and stable heat dissipation performance. Equipped with a high-quality low-loss magnetic core, it maintains accurate current transformation ratio and ultra-low measurement error, effectively resisting strong electromagnetic interference in complex UHV power grid environments.
Built with a fully sealed integrated structure and dedicated metal expander, this 220kV current transformer completely avoids oil leakage, moisture and dust intrusion. The high-strength anti-fouling porcelain sleeve with multi-layer anti-corrosion treatment enables reliable all-weather operation in harsh working conditions, including high altitude, low temperature and coastal salt fog polluted areas.
Optimized with scientific winding layout and balanced structural design, the LVB-220W2 features strong overload resistance and low operating noise. It supports multiple precision grade options, boasts long service life and low daily maintenance, effectively cutting operational and maintenance costs for 220kV power grid construction and upgrading projects.
As indispensable core equipment for 220kV ultra-high voltage power engineering, the LVB-220W2 outdoor oil immersed current transformer delivers superior measurement precision and stable operational performance. We provide global clients with factory direct supply, complete certification documents and professional one-stop after-sales service.
