LB5-66(W)
Adopting mature oil insulation structure and high-purity insulating oil, the LB5-66(W) boasts reliable high-voltage insulation and stable heat dissipation performance. Equipped with a high-quality magnetic core, it maintains accurate current transformation ratio and low measurement error, effectively resisting electromagnetic interference in complex power grid operating environments.
Featured with a fully sealed integrated structure, this 66kV current transformer thoroughly prevents oil leakage, moisture and dust intrusion. The high-strength anti-fouling porcelain sleeve with multi-layer anti-corrosion treatment supports stable all-weather operation in harsh environments, including high altitude, low temperature and coastal salt fog polluted areas.
Optimized with scientific winding layout and balanced structural design, the LB5-66(W) has strong overload resistance and low operating noise. It features long service life and low daily maintenance, greatly reducing operational and maintenance costs for 66kV power grid construction and renovation projects.
As essential core supporting equipment for 66kV power engineering, the LB5-66(W) outdoor oil immersed current transformer delivers high measurement precision and superior operational stability. We provide global customers with factory direct supply, complete certification documents and professional one-stop after-sales service.
