LRGBJ-35/66/110/220
Adopting mature oil-paper insulation structure and high-purity insulating oil, the LRGBJ series features uniform electric field distribution, low dielectric loss and excellent heat dissipation performance. Equipped with high-quality low-loss magnetic cores, the transformers maintain stable current transformation ratio and ultra-low measurement error, effectively resisting strong electromagnetic interference in complex power grid operating environments.
Designed with a fully sealed integrated structure and professional pressure protection structure, the LRGBJ series completely avoids oil leakage, moisture and dust intrusion. The high-strength anti-fouling and multi-layer anti-corrosion porcelain sleeve enables stable all-weather operation in harsh scenarios, including high altitude, low temperature, desert and coastal salt fog polluted areas.
Optimized with scientific winding layout and balanced structural design, LRGBJ-35/66/110/220 current transformers feature strong overload resistance and low operating noise. With multiple precision grade options and reliable structural stability, the series boasts long service life and low daily maintenance, effectively reducing operational and maintenance costs for power grid construction and renovation projects.
As versatile core equipment for medium and ultra-high voltage power engineering, the LRGBJ series outdoor oil immersed current transformers deliver outstanding measurement precision and operational stability. We provide global customers with factory direct supply, complete certification documents and professional one-stop after-sales service for various power project demands.
