LVQB-220

LVQB-220 is a professional SF6 gas-insulated outdoor high voltage current transformer applied to 220kV ultra-high voltage power systems. Complying with IEC and GB standards, it is widely used in UHV outdoor substations for current metering, real-time grid monitoring and relay protection.
Adopting high-quality magnetic core and precision winding process, the LVQB-220 features extremely low measurement error and high conversion accuracy. It maintains stable current transmission performance, providing precise and reliable data for electric energy metering and power grid operation analysis.
Equipped with advanced SF6 sealed gas insulation structure, the transformer has excellent dielectric strength and superior arc extinction capability. It avoids insulation aging and partial discharge problems, ensuring long-term safe and stable operation under high voltage conditions.
The fully enclosed integrated structure delivers outstanding waterproof, dustproof and anti-aging performance. It adapts to complex outdoor environments and extreme weather, supporting reliable all-weather continuous operation.
With compact structural layout and high mechanical stability, LVQB-220 is easy to install and requires low daily maintenance. It effectively reduces operation and maintenance costs for 220kV power grid construction and upgrading projects.
As core gas-insulated measuring and protection equipment for UHV power systems, LVQB-220 current transformer features high precision and strong environmental adaptability. We provide global customers with factory direct supply, complete certifications and professional one-stop after-sales service.
